ProxyTool Documentation

Complete reference for configuring proxies, chains, routing rules, DNS settings, and monitoring. Everything you need to get the most out of ProxyTool.

Core Features

Getting Started

ProxyTool is a Windows desktop application that routes your internet traffic through proxy servers at the kernel level. It intercepts connections using a WFP (Windows Filtering Platform) driver, giving you full control over which applications use which proxy — without modifying individual app settings.

Quick Setup (3 Steps)

  • Add a proxy — Enter your proxy server details (host, port, protocol) or paste a proxy string
  • Create a routing rule — Choose which applications or traffic should use the proxy
  • Activate — Traffic is immediately routed through the proxy

Account & Sign-In

ProxyTool uses a unified account for the web dashboard and desktop client. Sign in at /auth/login with email and password. If two-factor authentication is enabled, complete the TOTP or email OTP step before access is granted.

Desktop Sign-In The desktop client opens your browser for login using a secure PKCE flow. After you authenticate, the client receives a one-time token and creates a session — no password is stored locally.
Device Consent Each desktop installation registers as a device on your account. You must confirm adding a new device when your subscription's device limit allows it.
License Slots Your subscription includes a fixed number of device slots (shown in Settings → Subscription and on the web dashboard Devices page). Removing a device frees a slot for another installation.
Web Dashboard Administrators manage fleet devices, policies, and restrictions at /dashboard. See the Web Dashboard section for management documentation.

Dashboard at a Glance

The Dashboard is your central hub — it shows everything happening on your network in real time. Here's what each section does:

Stat Cards Five key metrics at the top: Active Connections, Proxies (online / total), Rules (enabled / total), Data Transfer (sent / received with a progress bar), and Uptime since last start.
Proxies Shows all configured proxies with their protocol badge (SOCKS5, HTTPS, etc.), server address, country flag, latency, and connection status. Click + Add to configure a new one.
Routing Rules Quick view of your active rules — which apps route through which proxy. Toggle rules on/off directly from the dashboard. The Default rule handles all unmatched traffic.
Chains Proxy chains with their type: Simple (sequential), Redundancy (failover), or Load Balancing (round-robin). Shows which proxies are chained together.
Bandwidth Real-time traffic chart showing inbound, outbound, and average throughput over the last 60 seconds. Adjustable refresh interval (1s–10s).
Live Connections Table of all active connections with process name (chrome.exe, msedge.exe, etc.), target domain, connection time, matched rule, proxy used, and bytes sent/received. Use Freeze to pause the live feed.
Live Log Stream Detailed event log with verbosity filters (Normal, Verbose, Debug, Error) and source filters (All, Backend, Connections). Shows TCP open/close events, proxy handshakes, DNS resolutions, and error details. Toggle Follow: On to auto-scroll.

Customize Your Dashboard

Click Customize in the top-right corner to enter edit mode. A toolbar appears at the top of the dashboard where you can control every section individually.

Stat Cards

Toggle each metric card on or off — disabled cards are hidden from the dashboard entirely.

Layout Options

  • Connections Height — Choose between 280px, 400px, 520px, 640px, or 760px to control how many connection rows are visible without scrolling
  • Reorder — Drag the arrow handles between stat cards to rearrange their order
  • Fine-tuning — Drag the grip under the Connections panel to adjust its height precisely

Click Done to save your layout. Use Reset All to restore the default arrangement, or Clear to remove all customizations and start fresh.

ProxyTool requires Windows 10+ (64-bit) and administrator privileges for the kernel driver. The driver is EV code-signed — Windows SmartScreen will not show an unknown publisher warning.

Adding a Proxy

Click Add Proxy on the Proxies page to open the configuration dialog. You can either fill in fields manually or paste a proxy string for instant setup.

Server Details

These fields are identical for every proxy type. Enter address details manually or use Quick Add: paste a proxy string (e.g. socks5://host:port:user:pass) or a curl -x command and all fields auto-fill instantly.

Proxy Name Display name or Quick Add string. Supports formats from providers like Evomi, Thordata, and others.
Host Address IP address or hostname of the proxy server.
Port Port number (1–65535). 8080
Proxy Type Protocol selector — HTTP, HTTPS, SOCKS4, or SOCKS5. The options panel below changes based on this selection.

Options by Protocol

The options shown below the protocol selector differ depending on the type you choose. Use the carousel tabs above to compare each protocol side by side.

Options Panel at a Glance
Option HTTP / HTTPS SOCKS4 SOCKS5
Requires Authentication Username + Password + Method selector (Basic / NTLM / Negotiate) N/A — replaced by User Identification Username + Password (auto-negotiated)
User Identification N/A User ID string (ident-based access, no password) N/A
SOCKS4a Extension N/A Toggle — enables remote DNS via proxy N/A (remote DNS built-in)
Send User-Agent Toggle — sends browser User-Agent header in CONNECT requests N/A N/A
Cost per GB Yes Yes Yes
Advanced Options Yes Yes Yes

Authentication Details

Toggle Requires Authentication (or User Identification for SOCKS4) to reveal credential fields. The layout changes per protocol:

Authentication by Protocol
Feature HTTP / HTTPS SOCKS4 SOCKS5
Credential fields Username + Password User ID only (no password) Username + Password
Auth method Basic, NTLM, or Negotiate (Kerberos) — dropdown selector N/A — ident string sent with CONNECT N/A — method auto-negotiated (RFC 1929)
Use Current User Login Yes (NTLM/Negotiate — uses Windows SSPI credentials) N/A N/A

Send User-Agent (HTTP / HTTPS only)

When enabled, ProxyTool adds a User-Agent header to the HTTP CONNECT handshake. Some proxies require this to allow the connection. A default Chrome 131 string is pre-filled, but you can set any custom value. This option does not appear for SOCKS4 or SOCKS5 because these protocols do not use HTTP headers.

SOCKS4a Extension (SOCKS4 only)

Standard SOCKS4 resolves hostnames locally before forwarding — which leaks DNS queries. With SOCKS4a enabled, the hostname is sent to the proxy for remote resolution, keeping your DNS private.

How SOCKS4a remote DNS works

ProxyTool sends a dummy IP (0.0.0.1) along with the target hostname. The proxy resolves the hostname on its end — your local DNS never sees the domain name.

ModeDNS ResolutionPrivacy
SOCKS4 (off)Client resolves locally to IPv4DNS visible to ISP
SOCKS4a (on)Proxy resolves remotelyDNS hidden from ISP

Cost per GB

Available for all protocol types. Enter your cost rate (e.g. $2.50 /GB) to enable real-time cost tracking in the Connection Monitor — especially useful for residential or metered proxies.

Advanced Proxy Settings

Expand the Advanced Options section in the Add Proxy dialog to access these settings. They apply to all proxy types unless noted.

Option Default What it does
Ask Credentials if Empty On Shows an interactive login prompt at connect time if no credentials are saved for this proxy
Ask Credentials if Auth Fails On Re-prompts for credentials when the proxy rejects authentication (HTTP 407, SOCKS rejection)
Use Authentication URL Off Authenticate via a URL instead of stored credentials. Used for enterprise proxies (e.g. Blue Coat) that use web-based auth portals
Authentication URL The URL to use for authentication. Supports embedded credentials: scheme://user:pass@host. Required when the toggle is enabled
Use Target Hostname Off Sends the original hostname (not resolved IP) in the proxy CONNECT request. Useful when the proxy needs to see domain names for routing or logging
When Use Authentication URL is enabled, the credential prompt options are automatically disabled and stored username/password are cleared — the URL handles all auth at runtime.

Inline Proxy Checker

Before saving, click Check to verify connectivity. The checker runs a multi-step test against a configurable target (default: google.com):

  • Proxy connection — TCP connect to the proxy server, measures latency
  • HTTPS handshake — Sends the CONNECT request to the proxy
  • Authentication — Handles proxy auth (407 response → sends credentials)
  • Credential check — Verifies credentials were accepted (HTTP 200)
  • Target connection — Reaches the target through the proxy end-to-end

All steps show a green checkmark on success with detailed status messages. The total latency is displayed at the top right (e.g. 99 ms), and a summary line confirms the result: PASSED — All tests OK.

Proxy Checker — 5 steps passed: Proxy connection, HTTPS handshake, Authentication, Credential check, Target connection (99ms) Inline Proxy Checker — all 5 tests passed (99 ms latency) with target google.com · Click to enlarge

Managing Proxies

The Proxies page displays all configured proxy servers in a sortable table with real-time status indicators.

Proxies page showing proxy table with status, latency, location, and action controls Proxies — Server list with protocol, address, location, latency, and quick actions · Click to enlarge

Table Columns

Column Shows
Name Display name you assigned
Type Protocol badge (HTTP, HTTPS, SOCKS4, SOCKS5)
Address host:port
Location Country flag + city (auto-detected via GeoIP lookup)
Status Active (green dot) or Inactive (gray dot)
Latency Response time in ms, color-coded (green/yellow/red)
Actions Toggle on/off, Edit, Delete, Test

Filters & Search

  • Search — Filter by name, address, or location
  • Type filter — All / HTTP / HTTPS / SOCKS4 / SOCKS5
  • Status filter — All / Active / Inactive

Actions

  • Toggle — Activates/deactivates the proxy (starts or stops the bridge)
  • Edit — Reopens the Add Proxy dialog in edit mode with all fields pre-filled
  • Delete — Stops the proxy if active, then removes it. Shows a warning if the proxy is used in chains or rules
  • Test — Runs the connectivity checker without opening the dialog
Newly added proxies start as inactive. They only route traffic when activated directly or referenced by an active routing rule.

Routing Rules

Rules determine which traffic goes through which proxy (or chain), goes direct, or gets blocked. They are evaluated top-to-bottom by priority — the first matching rule wins. Click + Add Rule to open the configuration dialog.

Rules Overview

The Rules page lists all configured routing rules with their priority number, action badge (Proxy / Direct / Block), on/off toggle, and summary tags showing matched apps, hosts, ports, and protocol. Use the up/down arrows on the right to reorder priorities — the first matching rule wins.

Rule Setup

The top half of the dialog defines what traffic this rule matches. All four criteria are optional — leave a field empty (or *) to match everything.

Field Format Examples
Rule Name Descriptive label Google Services, Dev Server
Application / Process Name, path, wildcards (*, ?), multiple separated by ;. Use Browse to pick an EXE. chrome.exe; msedge.exe, *bin*, pid=1234
Target Hosts Domain patterns, comma-separated. * = all hosts. *.google.com, api.example.org
Target Ports Numbers, comma-separated. * = all ports. 80,443,8080

Protocol

Select which transport protocol this rule applies to. The dropdown offers TCP, UDP, or BOTH. Note that UDP routing requires a SOCKS5 proxy — HTTP and SOCKS4 proxies only support TCP.

Debugging UDP traffic: Enable Traffic Dump under Settings → General → Diagnostics to capture detailed .dmp logs of all proxied TCP and UDP connections. Useful for verifying that game, VoIP, or streaming traffic is actually routed through your proxy.

Actions

The Action dropdown defines how matched traffic is routed. Each action type shows different follow-up options:

Action Types at a Glance
Action What it does Follow-up options
Direct Bypass proxy — traffic goes straight to the destination Priority, Enable toggle
Proxy Route through a specific proxy server Proxy selector (shows all configured servers with protocol badge), Protocol (TCP/UDP/BOTH), Priority, Enable toggle, Advanced Options
Chain Route through a proxy chain Chain selector (shows all configured chains), Priority, Enable toggle, Advanced Options
Block Drop the connection — app receives connection refused Priority, Enable toggle

When selecting Proxy, the dropdown lists all configured servers with their protocol badge (HTTPS, SOCKS5). When selecting Chain, you choose from your configured chain setups (Load Balancing, Redundancy, Simple).

Priority & Enable

Every rule has a Priority level (1 = lowest, 10 = highest). Higher priority rules are evaluated first. The Enable this rule immediately toggle (on by default) activates the rule right after creation — disable it to save a rule for later use.

Advanced Routing Options

Expand Advanced Options at the bottom of the Add Rule dialog (available for Proxy and Chain actions) to access network interface control and IPv6 settings.

Option Default Description
Outgoing Interface Automatic Interface Force this rule's traffic through a specific network adapter (e.g. WiFi, Ethernet, VPN). Automatic lets the OS decide.
IPv6 through proxy Off Off: IPv6 connections are dropped and logged to the leak-prevention log. On: IPv6 traffic is forwarded through the rule's proxy or chain.
UDP/QUIC note: When using TCP-only proxies (HTTP or SOCKS4), UDP traffic from matched applications (including QUIC/HTTP3 and WebRTC) will be dropped if "Block unsafe UDP fallback" is enabled in DNS settings. Only SOCKS5 supports UDP relay.

Proxy Chains

Proxy chains combine multiple proxies into a single routing target. ProxyTool supports three chain types — Simple (sequential multi-hop), Redundancy (automatic failover), and Load Balancing (random distribution). Click + Add Chain to open the configuration dialog.

Chains Overview

The Chains page lists all configured chains with their type badge (Simple, Load Balancing, Redundancy), proxy count, and a route visualization showing the traffic path (e.g. Static Test Proxy → TestProxy1). Expand a chain to see per-proxy health status with test results and latency.

You need at least 2 proxies configured before you can create a chain. Chains are activated by assigning them to a routing rule — they don't have their own on/off toggle.

Chain Setup

Enter a Chain Name, then select one of the three chain types. Each type shows its own configuration options below the selector. The Available Proxies panel lists all configured proxy servers — click the + button next to a proxy to add it to the chain.

Chain Type Comparison
Aspect Simple Redundancy Load Balancing
How it works All proxies in sequence (multi-hop) One proxy at a time (failover) Random proxy per connection
Traffic flow Client → A → B → Target Client → first working proxy → Target Client → random proxy → Target
Use case Multi-hop anonymity High availability / backup proxies IP rotation / load distribution
On failure Whole chain fails Tries next proxy in order Excludes failed proxy from pool
Order matters? Yes — defines hop sequence Yes — defines failover priority No — random selection from pool

Simple Sequential Chain

Routes traffic through every proxy in order as a true multi-hop chain. Each proxy becomes a hop between your device and the destination. Adds latency but increases anonymity. The order you set in the Chain Order section determines the hop sequence.

HTTP/HTTPS proxies may only be the last hop in a Simple chain. Earlier hops must be SOCKS4 or SOCKS5 due to protocol limitations.

Redundancy Failover Chain

Uses one proxy at a time from the ordered list. Tries the first enabled proxy; if it fails validation within the timeout, automatically switches to the next.

Option Default Description
Connection Timeout 10s How long to wait before declaring a proxy failed. Adjustable with + / buttons (1–120 seconds).
Connect directly if all fail Off On: bypass proxies entirely when all fail. Off: block the connection.
Recheck failed proxies 300s Background timer re-tests failed proxies automatically. Set to 0 to disable.

Load Balancing Random Distribution

Distributes connections across multiple parallel proxies. Each new connection gets assigned a random proxy from the pool.

Option Default Description
Same proxy for same process (PID) Off Off: rotate proxy per connection (even within the same app). On: lock one proxy per process for session stickiness.
Use PID stickiness when an application needs a stable IP (e.g. logged-in sessions) but you still want different apps to use different proxies from the pool.

Creating a Chain

Steps

  • 1. Name your chain — Enter a descriptive name (e.g. "Secure Multi-Hop")
  • 2. Select chain type — Simple, Redundancy, or Load Balancing — each shows its own configuration options
  • 3. Add proxies — Click the + button next to a proxy in the "Available Proxies" panel. Proxies show their protocol badge (HTTPS, SOCKS5) and can only appear once per chain.
  • 4. Set order — In the Chain Order section, use the ▲ ▼ arrow buttons to move proxies up or down. Traffic flows top to bottom. Click to remove a proxy from the chain.
  • 5. Configure options — Set type-specific options (timeout for Redundancy, PID stickiness for Load Balancing)
  • 6. Save — Click Add Chain. Assign the chain to a routing rule to start using it.

Chain Order

The Chain Order section shows all added proxies as numbered cards. Each card displays the proxy name, address, and protocol badge. Use the (up) and (down) arrow buttons to reorder — traffic flows from position 1 downward. A visual arrow connects the hops to illustrate the routing path. The counter (e.g. 2 proxies) shows how many are in the chain, with a minimum of 2 required.

Chain List Features

  • Type badge — Color-coded: Simple, Load Balancing, Redundancy
  • Route visualization — Shows the proxy flow: Proxy A → Proxy B → ...
  • Per-proxy health — Expand a chain to see individual proxy test results with latency, e.g. PASSED — All tests OK (98 ms)
  • Edit / Delete — Edit reopens the dialog, Delete removes the chain. Shows a warning if the chain is used in routing rules.

DNS & Name Resolution

The DNS page controls how hostnames are resolved and provides leak-prevention features that keep your real IP address hidden. Three tabs at the top let you switch between detection modes, while the settings below fine-tune privacy behaviour.

Current DNS Mode

The status badge in the top-right corner (Local DNS or Via Proxy) shows the active resolution path at a glance. Three tabs below it control the detection mode:

Tab How it works Best for
Automatic Detection Monitors network conditions and switches to proxy DNS automatically when local DNS is unavailable General use — best balance of speed and privacy
Local Resolution Always uses the system's own DNS resolver Performance priority — fastest resolution
Exclude / Name List Fine-tune which domains bypass proxy DNS. Supports wildcards (*, ?) and constants like %ComputerName% Hybrid setups where some domains must resolve locally

Proxifier DNS Settings

Two toggles control the connection between auto-detection and proxy resolution:

  • Detect DNS settings automatically — monitors network conditions and switches DNS mode when local DNS becomes unavailable (on by default)
  • Resolve hostnames through proxy — sends all DNS queries through the proxy server instead of local DNS. When enabled, the badge changes to Via Proxy and the detection tab switches to Manual / Proxy
Privacy note: When using "Resolve via proxy", ProxyTool may still need to resolve your proxy endpoint hostname locally. This does not reveal the websites you visit, but your local DNS may see the proxy provider domain. To avoid this, configure the proxy using an IP address instead of a hostname.

IP Protection & Leak Prevention

IP Protection panel with UDP fallback, IPv6, and Strict DNS toggles

Scroll down on the DNS page to find the IP Protection panel. These settings prevent traffic from leaking outside the proxy when the operating system or applications attempt alternative network paths. You can enable everything at once or pick individual modules in custom mode.

Option Default What it prevents
Enable all IP protection Off Master toggle — activates all protection modules below and locks them on
Block unsafe UDP fallback Off Blocks direct UDP connections (incl. QUIC/HTTP3 and WebRTC) when a rule requires proxying but the route cannot carry UDP
Protect IPv6 UDP paths Off Blocks IPv6 UDP traffic that is not currently kept on a safe proxy relay path
Strict DNS over proxy Off If DNS should go through the proxy, blocks unsupported query types or missing safe paths instead of allowing direct fallback
Custom mode: When the master toggle is off, the info banner reads "Custom mode: you can enable only the protection modules you want." Toggle each option individually to match your privacy requirements.
Windows Smart Multi-Homed Name Resolution (SMHNR)

Windows may send DNS queries across all available network interfaces simultaneously (Smart Multi-Homed Name Resolution), which can bypass proxy DNS even when "Resolve via proxy" is enabled.

When IP Protection or Strict DNS is active, ProxyTool warns about this and provides registry commands to disable it:

DisableSmartNameResolution = 1 and DisableParallelAandAAAA = 1

Additionally, disable browser Secure DNS (DoH) to prevent browsers from resolving names independently.

Traffic Monitor

The Traffic Monitor page is your real-time command center for network visibility. Two tabs at the top — Analytics and Connections — let you switch between high-level insights and a detailed connection table. Use Freeze to pause all counters for analysis, or Clear to reset session data.

Summary Cards

Four cards at the top provide session-level metrics at a glance:

Active Connections Current number of open connections this session
Total Sent / Received Cumulative bytes with real-time upload/download speed indicators
Bandwidth Combined traffic total with upload and download speed

Analytics Tab

The Analytics tab organizes traffic data into several cards that scroll vertically:

Card What it shows
Traffic Monitor Per-app bandwidth bars (e.g. Chrome 1.9 MB, MS Edge 2.4 MB) with total and primary proxy name
Protection Overview Ring chart showing proxied vs. direct ratio (e.g. 100% Protected), geo-badges (DE, US), and a privacy assessment
Proxy Usage Stacked bar with traffic distribution across proxies (e.g. TestProxy1 76%, Static Test Proxy 24%, Direct 0%)
Security Shield Threats Blocked + Conn Errors counters. Click any event to expand Connection Flow details: process path, host, IP, proxy route, bytes sent/received, and a diagnosis (e.g. "Proxy handshake failed")
Proxy Health Per-proxy quality score ring (0–100), connection count, error rate, average duration, and traffic volume
Domain Intelligence DNS-based category ring (Google, Microsoft, Tracking, Streaming, Cloud, Other) with per-domain breakdown showing request count and traffic percentage
Protocol Insights TCP/UDP split, TLS encryption ratio, DNS virtualization percentage, DNS leaks blocked, IPv4/IPv6 balance, UDP relay status, and session history

Connections Tab

Connections table with process, target, time, rule/proxy, sent/received

The Connections tab shows a live table of every active and recent connection:

Column Shows
Process Application name + PID (e.g. chrome.exe PID: 800)
Target Hostname and resolved IP with port
Starts Connection start time
Time Connection duration (or "Closed" for finished connections)
Rule / Proxy Which rule matched and the full proxy route (e.g. "Static Test Proxy • isp-2.evomi.com:12345 HTTP")
Sent / Recv Bytes transferred in each direction

Connection Forensics

Scroll down in the Connections tab to find Connection Forensics. Two sub-tabs — Domains and By Proxy — provide deep analysis:

  • Domains — Shows all contacted domains with request count and traffic percentage. The overall block rate is displayed in the header
  • By Proxy — Expand each proxy to see success rate, block rate, wasted data, and blocked domains with frequency

Cost Overview

The Cost Overview card calculates real-time proxy expenses based on the per-GB rate you set on each proxy. The total cost badge (e.g. $0.2298 total) appears in the top-right corner. Four tabs let you slice the data differently:

  • Overview — Unified ranking of all proxies, processes, and domains sorted by traffic. Each entry shows a type badge (Proxy / Process / Domain), traffic volume, and cost
  • By Proxy — Traffic and cost per proxy endpoint with connection count breakdown
  • By Domain — Ranked list of domains by traffic, useful for identifying bandwidth-heavy sites
  • By Process — Per-application cost breakdown so you can see which processes generate the most proxy traffic

Cost Optimization

The Cost Optimization card identifies wasted proxy traffic — connections that were blocked or failed (RST) but still consumed bandwidth. The badge (e.g. $0.0002 wasted) highlights the total wasted cost. Click any entry to expand details:

  • Overview — Ranked list of domains with wasted bytes, associated proxy and process, and cost per entry
  • By Proxy — Click a proxy to see its top wasted domains and processes. Shows total block count, success rate, and block rate per proxy
  • By Domain — Wasted traffic grouped by domain name
  • By Process — Wasted traffic grouped by application (e.g. msedge.exe, chrome.exe)
RST classification: RST <500ms = IP blocked • FIN <300ms = soft-block/captcha • Normal RST after >2s = healthy TCP cleanup. This helps distinguish actual blocks from normal connection teardown.

TLS Fingerprint Detection

ProxyTool monitors TLS Client Hello packets and compares JA3 fingerprint hashes against a known database. When a connection's fingerprint indicates a potentially detectable automation tool, a warning card appears in the Analytics tab with fix suggestions.

TLS Fingerprint Warning — curl.exe detected as DETECTABLE with fix suggestion

In this example, curl.exe was flagged as DETECTABLE because its TLS fingerprint does not match any known browser. The warning card explains that anti-bot systems like Cloudflare, Akamai, and DataDome compare JA3 hashes against known browsers, and suggests using curl_cffi, Camoufox, or Playwright with stealth plugins instead.

TLS Risk Levels
Risk Fingerprint Source Badge Action
Low Chrome, Firefox, Safari, Edge (real browsers) No warning Normal browser-like traffic — no detection risk
Medium Playwright, Puppeteer, Selenium, curl_cffi, Camoufox DETECTABLE Destination may flag as automation — consider fingerprint masking
High Python requests, curl, Go net/http, Java HttpClient, wget, Scrapy BLOCKED Known bot fingerprint — likely blocked by anti-bot services

The warning panel shows: process name, number of flagged connections, affected domains (last 5), and process-specific suggestions for fixing the fingerprint.

ProxyTool does not modify your TLS fingerprint. The warning is purely informational — it tells you what a destination server could detect based on the client's TLS handshake pattern.

Cost Tracking

If you've configured a Cost per GB rate on your proxies, the Monitoring page calculates real-time spending based on actual traffic.

How Cost Is Calculated

cost = (bytes_transferred / 1,073,741,824) × cost_per_gb
  • Calculated per proxy based on the rate set in the proxy's configuration
  • Includes both upload and download bytes
  • Displayed with up to 6 decimal places for precision on small transfers
  • Visible in Security Shield events and the Cost Optimization card

Cost Optimization

When you have at least 5 proxied connections, the analytics tab shows a Cost Optimization card that breaks down wasted bandwidth by proxy, domain, and process — helping you identify where to reduce costs.

Application Settings

The Settings page provides centralized control over subscription management, appearance, system behavior, privacy, and diagnostics. A search bar at the top filters settings in real time — type any keyword to locate and navigate directly to the matching setting.

Settings Search

The search bar at the top of the Settings page provides instant filtering. Typing a keyword (e.g. "tray", "DNS", "encryption") highlights and scrolls to the matching setting, making it easy to locate options without browsing through tabs.

Subscription

Setting Description
Current Plan Displays the active subscription tier (Free, Pro, etc.) and expiration date
Device Management Shows the number of device slots used vs. available. Displays a warning when the device limit is reached
Sync Status Indicates whether profile and settings are synced with the cloud account
User Account Shows account name and email. Provides a Logout button to disconnect the device from the account

General

Setting Default Description
Theme System Light or Dark appearance
Language English English or Deutsch
System Tray Icon On Show ProxyTool icon in the notification area
Minimize to Tray On Close button minimizes to tray instead of quitting
Desktop Notifications On Show system notifications for connection events

Safety

Setting Default Description
Connection Loop Detection On Detects and blocks runaway proxy redirection loops
DNS Resolution Loop Detection On Detects DNS-over-proxy loops and auto-disables proxy DNS to prevent lockout

Diagnostics

Setting Default Description
Traffic Dump Off Save proxied TCP traffic as .dmp files for debugging. Warns when files exceed 1000 or 500 MB total

Profiles & Migration

Profiles save your complete configuration (proxies, chains, rules, DNS settings) as portable .ppx files. You can maintain multiple profiles and switch between them.

Active Profile

The current workspace is auto-saved continuously. To persist a configuration as a named profile, use Save As. The active profile name is displayed at the top of the Profiles tab. Additional controls include:

  • New Blank — Reset to a clean empty configuration
  • Save As — Save current workspace as a named profile
  • Import — Load a .ppx file from disk (or a Proxifier .ppx/.xml)
  • Export — Save the current configuration to a file for sharing or backup

Saved Profiles

All saved profiles appear in a list below the active profile. Each entry shows the profile name and provides Load and Delete actions. The currently active profile is highlighted. Loading a profile replaces the entire active workspace configuration.

Profile Auto Update

Profiles can be fetched automatically from a remote server. This is useful for team deployments or managed environments where configuration changes need to propagate to all devices.

Setting Description
Auto Update Toggle Enable or disable automatic profile fetching at startup
URL Remote URL pointing to a .ppx file or a folder containing multiple profiles
Update Mode Dropdown to select update behavior (e.g. replace entire profile, merge additions only)
Keep Credentials When enabled, existing proxy passwords are preserved during the update
Update Now / Stop Manually trigger an immediate update or cancel an in-progress fetch
If the auto-update URL uses HTTP (not HTTPS), passwords in the downloaded profile travel in clear text over the network. The UI displays a yellow security warning when an insecure URL is configured.

Password Encryption

Profile files can encrypt stored proxy passwords using one of four modes. The encryption mode selector is a radio button group in the Profiles tab.

Mode Security Level Notes
Disabled None Passwords stored as plain text in profile
Basic Medium Encrypted with ProxyTool static key (portable between devices)
Current User Account High Encrypted with Windows DPAPI — locked to the current user account on this device
Master Password Highest AES-256 encryption with a user-chosen master password. Portable between devices; password is required each time the profile is loaded

Profile Files

Profiles are stored as XML .ppx files. The Profiles tab shows the user profile directory path with a copy button for quick access in file explorer.

  • User profile directory — Default location where named profiles are saved
  • Default.ppx — Place this file in the application directory or C:\ProgramData\ProxyTool\ to auto-load a profile for all users on the machine
  • CLI loading — Run ProxyTool.exe profile.ppx [silent-load] to load a specific profile at launch. The silent-load flag suppresses the load confirmation dialog
Editing an existing proxy reopens the same Add Proxy dialog with all fields pre-filled, so you can adjust any setting without re-entering everything from scratch.

Migrate from Proxifier

ProxyTool can import your existing Proxifier configuration (.ppx / .xml) including proxy servers, chains, rules, DNS settings, and leak-protection options. The import wizard detects all components and guides you through any manual steps required.

What It Imports

  • Proxy servers — Host, port, protocol, and authentication credentials
  • Proxification rules — Application-based routing rules (process name → proxy assignment)
  • Proxy chains — Multi-hop configurations and failover setups
  • DNS settings — Name resolution preferences from the Proxifier profile
  • Leak-protection options — UDP blocking and related privacy settings

Encryption Handling

Proxifier profiles may store proxy passwords using different encryption methods. ProxyTool detects the encryption mode and handles decryption automatically when possible:

Encryption Mode Auto-Decrypt Details
Basic (Static Key) Not yet Proxifier uses a built-in static key. Auto-decryption support is planned; use Password Manager for now
Current User Account (DPAPI) Yes* Automatically decrypted if importing on the same Windows user account that created the Proxifier profile. Fails on a different PC or user — use Password Manager
Master Password Not yet Requires the original master password. Auto-decryption support is planned; use Password Manager for now
When DPAPI decryption fails (different PC or user account), the import wizard displays a DPAPI warning and opens the Password Manager so you can manually enter the passwords.

Password Manager Workflow

The Password Manager appears inside the import modal when automatic decryption is not available. It provides a bulk interface for entering proxy passwords:

  • Proxy selection — Select individual proxies via checkboxes, or use the header checkbox to select all
  • "All same" bulk-apply — Enter one password and apply it to all selected proxies at once
  • Per-proxy fields — Individual password input fields for each proxy that needs credentials
  • Apply button — Commits the entered passwords to the import configuration

After Import

Imported items are added to the current active configuration. Proxies, chains, rules, and settings merge into the workspace immediately. To persist the imported configuration as a named profile, use Save As in the Profiles tab.

The final review screen lists all detected proxies, rules, and settings before committing. Use the Cancel button to abort without changes, or Import to apply everything to the current workspace.

Web Dashboard Overview

The web dashboard at /dashboard is where administrators manage organizations, deploy proxy configurations to managed devices, and control what end users can do in the desktop client. It is separate from the desktop app's own Dashboard page — this section documents the web admin portal.

Deployment Flow

Managed configurations reach devices through groups — not by assigning directly to individual devices:

  1. Create a Policy — define proxies, chains, rules, DNS, and app settings in the Policy Editor
  2. Create a Restriction (Team Premium) — optionally limit what users can change in the desktop client
  3. Create a Device Group — add the target devices as members
  4. Assign Policy & Restriction to the group — from the Policy or Restriction editor (Summary / Assignments tab)
  5. Push — configurations are delivered to all devices in the group via MQTT
  6. Verify in Fleet — check device status, applied policy version, and active configuration
One policy + one restriction per group. Each device group can have at most one assigned policy and one assigned restriction. Assigning a new one to a group that already has one triggers an override confirmation dialog.
Policies vs Restrictions
  • Policy = what configuration devices use (proxies, rules, chains, DNS, app settings)
  • Restriction = what users are allowed to see and change in the desktop client

Device Groups

Device groups organize managed devices for bulk policy and restriction deployment. Navigate to Management → Groups in the web dashboard.

Creating a Group

NameDisplay name for the group (e.g. "Engineering Devices")
DescriptionOptional notes about the group's purpose
TypeAlways Device Group — groups contain managed fleet devices

Managing Members

  • + Add Devices — select one or more fleet devices from a multi-select panel and add them to the group
  • Remove — remove individual devices from the expanded group view
  • Device count and member previews are shown in the collapsed group row

Assigned Policy & Restriction

When a group has an assigned policy or restriction, they are shown in the group detail panel. To change assignments, use the Policy Editor (Summary tab) or Restriction Editor (Assignments tab).

Assign policies and restrictions from the Policy/Restriction pages, not from the Groups page.

Policy Profiles

Policy profiles are managed configurations (proxies, chains, rules, DNS, app settings) that can be pushed to device groups. Navigate to Management → Policies.

Policy List

+ Create PolicyOpens the Policy Editor to build a new profile from scratch or import a .ppx file
AI AssistantChat-based helper to modify policy configuration using natural language
EditOpen the Policy Editor for an existing profile
Push & ReleaseDeploy the current policy version to all devices in assigned groups via MQTT
Download .ppxExport the policy as a Proxifier/ProxyTool profile file
Delete PolicyPermanently remove the policy profile

Apply Mode

AdditiveMerges the pushed policy with any existing local configuration on the device. Local settings not covered by the policy are preserved.
OverrideReplaces the device's entire configuration with the policy. Local settings are overwritten.

Group Assignment

From the expanded policy row or the Policy Editor Summary tab:

  • Select a group from the dropdown and click Assign to Group
  • If the group already has a different policy, a confirmation dialog asks whether to override
  • Assigned groups show device counts and online status; outdated devices (running an older policy version) are highlighted
  • Unassign removes the policy from a group without deleting the policy itself

Policy Editor

The Policy Editor has six tabs. Use Import .ppx to load an existing Proxifier or ProxyTool profile, or build from scratch. Save with Save or deploy immediately with Save & Push.

Tab: Proxies

Define proxy servers included in this policy. Toolbar: + Add Proxy, Expand All, Collapse All.

Tab: Summary

Shows policy statistics (proxy, chain, rule counts) and the Group Assignments section — assign or unassign groups directly from the editor before pushing.

Device Restrictions

Device restrictions control what end users can see and do in the desktop client. Available on Team Premium plans. Navigate to Management → Restrictions.

Restriction List

  • + New Restriction Profile — create with name and description
  • Each profile shows active restriction count and assigned group count
  • Edit opens the Restriction Editor
  • Delete removes the profile (also unassigns from groups)

Templates

Lock Policy (Full)Preset that disables proxy/rule/chain editing, locks DNS/leak protection, and locks most profile operations — maximum lockdown
Reset to DefaultRestore all toggles to permissive defaults (everything allowed, nothing hidden)

Save & Push

Save stores the restriction profile. Save & Push saves and immediately applies restrictions to all devices in assigned groups via MQTT.

Hide vs Allow vs Lock:
Hide (UI Visibility) — removes a page or section from the desktop UI entirely.
Allow (Permissions) — when OFF, the user cannot perform that action (e.g. add a proxy).
Lock (Permissions) — when ON, the user cannot change that setting even if they can see it.

Restriction Editor

Three tabs: UI Visibility, Permissions & Locks, and Assignments.

Frequently Asked Questions

What's the difference between SOCKS4, SOCKS4a, and SOCKS5?

SOCKS4 supports TCP only and requires the client to resolve DNS locally (your ISP sees the domain lookup). SOCKS4a is an extension that lets the proxy resolve DNS instead — better for privacy. SOCKS5 supports both TCP and UDP, has built-in username/password authentication, and always resolves DNS remotely by default. For most use cases, SOCKS5 is recommended.

Which chain type should I use?

Simple if you need multi-hop anonymity (traffic passes through all proxies). Redundancy if you need high availability and want automatic failover to a backup proxy. Load Balancing if you want to distribute connections across multiple proxies (useful for scraping or rate-limit avoidance). Enable "Same proxy per PID" in Load Balancing if an application needs a stable IP across its session.

When will I see a TLS fingerprint warning?

Warnings appear when an application produces a TLS fingerprint (JA3 hash) that matches known automation tools or bot-like clients. For example: Python's requests library, plain curl, Go's net/http, or Selenium/Puppeteer produce recognizable fingerprints that anti-bot services can detect. Real browsers (Chrome, Firefox, Edge) produce normal fingerprints and don't trigger warnings.

How do I prevent DNS leaks?

Enable "Resolve hostnames through proxy" in DNS settings. For maximum protection, also enable "IP Protection" which blocks unsafe UDP fallback, IPv6 leaks, and forces strict DNS-over-proxy. Additionally, consider disabling Windows Smart Multi-Homed Name Resolution (registry setting) and your browser's Secure DNS (DoH) feature, as these can bypass proxy DNS.

What happens if all proxies in a chain fail?

For Redundancy chains: if "Connect directly if all fail" is enabled, traffic bypasses proxies and goes direct. If disabled (default), the connection is blocked entirely. Failed proxies are automatically rechecked at the configured interval (default: every 5 minutes). For Load Balancing chains: there's no automatic recheck — use the "Reset Fail Status" button or manually re-test proxies. For Simple chains: the entire chain fails if any single hop fails.

Can I use HTTP proxies for UDP traffic (QUIC/WebRTC)?

No. HTTP and SOCKS4 proxies only support TCP. UDP traffic (including QUIC/HTTP3, WebRTC, mDNS) cannot be routed through them. If "Block unsafe UDP fallback" is enabled in DNS settings, UDP from matched applications will be dropped rather than sent direct. Use SOCKS5 if you need UDP relay support — it's the only protocol that handles UDP natively.

How is bandwidth calculated for billing?

Bandwidth = total bytes (upload + download) through proxy connections. Traffic that bypasses the proxy (via Direct rules or split tunneling) is never counted. Protocol overhead (proxy headers) is included but typically negligible (<1%). The "Cost per GB" rate set on each proxy is used for cost calculation in the Monitoring page — this is separate from your ProxyTool subscription.

What does "Use Authentication URL" do?

Some enterprise proxies (like Blue Coat/Symantec) require web-based authentication instead of inline credentials. When enabled, ProxyTool authenticates by accessing the specified URL rather than sending username/password in the proxy protocol handshake. The URL can contain embedded credentials (scheme://user:pass@host) or trigger a browser-based auth flow. This automatically disables the regular credential prompts.

Can I migrate from Proxifier?

Yes. Go to Settings → Profiles → "Migrate from Proxifier". Import your .ppx or .xml file — ProxyTool will import your proxy servers, chains, routing rules, DNS settings, and leak protection options. Passwords encrypted with DPAPI require the same Windows user account. After import, review the configuration in ProxyTool's UI before activating.

Does ProxyTool work with all applications?

Yes. ProxyTool operates at the kernel level using a WFP (Windows Filtering Platform) driver, intercepting traffic from any application — including games, desktop apps, CLI tools, and background services. Applications don't need built-in proxy settings. The only excluded processes are ProxyTool itself (to avoid loops) and system-critical Windows services (for stability).

What is the difference between a Policy and a Restriction?

A Policy defines the configuration deployed to devices — proxies, chains, rules, DNS, and app settings. A Restriction controls what end users can see and change in the desktop client (UI visibility and permission locks). Both are assigned to device groups and pushed via MQTT.

Can I assign multiple policies to one group?

No. Each device group can have exactly one policy and one restriction. Assigning a new policy to a group that already has one triggers an override confirmation. To use a different policy, assign it from the Policy Editor or Policies list — the previous assignment is replaced.

What does Additive vs Override apply mode do?

Additive merges the pushed policy with existing local configuration — settings not covered by the policy remain on the device. Override replaces the entire device configuration with the policy content. Use Override for strict managed deployments; use Additive when devices may have local additions.

What happens when I hide Proxies vs lock Add Proxy?

Hide Proxies (UI Visibility) removes the Proxies page from the sidebar entirely — the user cannot see or access it. Allow Add Proxy (Permissions) keeps the page visible but blocks creating new proxies when turned OFF. You can combine both: hide the page for a clean UI, or show it but lock editing.

Standard vs Team Premium — what management features do I get?

Standard includes Fleet, Groups, Policies, and Automations. Team Premium adds Users & Roles, Device Restrictions, Permissions & Roles, and organization-level AI credit pool management. Upgrade from Account → Billing in the web dashboard.

How does policy push reach devices?

When you click Push & Release or Save & Push, the server sends the policy (or restriction) to all online devices in assigned groups via MQTT. Devices apply the configuration and report back via heartbeat. Check Fleet for applied policy version and "Update pending" status if a device hasn't synced yet.

What is the difference between Fleet devices and License slots?

License slots (Devices page) track how many desktop installations your subscription allows — personal activations tied to your account. Fleet devices (Management → Fleet) are organization-managed endpoints enrolled for remote policy deployment, status monitoring, and restrictions. A device can be both a licensed installation and a fleet-managed device.

Where do I assign a policy to a group?

Assign from the Policy Editor → Summary tab or from the expanded policy row on the Policies list page. The Groups page shows assigned policy/restriction as read-only links — it does not perform assignments. The same applies to restrictions via the Restriction Editor → Assignments tab.
