How to Check an Antidetect or Proxy Profile in 2027

This is not a ranking of browsers

An antidetect browser keeps a profile: cookies, a proxy, a time zone, a language. ProxyTool does not do that job. ProxyTool is the client that sends the applications you choose through a proxy, including the ones with no proxy setting of their own.

The check below is for the profile or the proxy you already configured. The year is 2027 because this is the pass to run now, not because a number in the title makes an old list new. There is no winner among antidetect browsers on this page.

One page, five checks that start themselves

Open the six checks. Five of them start when the page loads. The proxy list waits until you paste one. Read them from the top.

1. Address. IP lookup shows the address this page loaded from and the network that owns it. Country, not a city. If this is not the exit you bought, stop. The rest of the page is describing the wrong connection.

1. Fingerprint. Browser fingerprint leads with what disagrees: clock against country, language, platform, a public WebRTC address. A green hash is not the result. A privacy browser that coarsens values on purpose is named as one, not scored as broken.

1. Automation. Bot detection says normal browser, privacy browser, or a browser a program is driving. The signal is named. An open DevTools window is not one of the signals.

1. DNS. DNS leak test names the resolver and whether its network is the one the page loaded from. A public resolver such as Cloudflare is not a leak on its own. Secure DNS in the browser is the usual reason the IP and the DNS disagree. Twelve lookups run without a second button.

1. WebRTC. WebRTC leak test calls a leak only when a public address is not the page address. A private address, a carrier address, and a .local name are the tunnel or the LAN. They are listed so you can see them. They are not printed as the leak.

That order is the order on the page: nothing to type, then the list.

Then the proxy line, if you have one

The proxy checker does not run until you paste a proxy. One line is enough to see the exit address, the network, and whether a forwarding header added another public address. Elite, anonymous, and transparent are labels other checkers invented. The header is the fact. The password is used for the check and not stored.

Skip this block when you are only looking at the browser in front of you. Use it when the thing you are judging is the proxy line itself.

What a pass is

A pass is five sentences that agree:

• The page address is the exit you meant.
• The clock and the language do not argue with that country, or you know why they do.
• The browser is not reporting that a program is driving it, unless it is.
• DNS is on the same network, or it is a public resolver you turned on.
• WebRTC has no second public address.

A miss is any one of those going the other way. Fix that one. Do not collect a score and call the profile clean because four of five were quiet. A check that did not run is not a pass. The longer version of why other sites print a different word for the same screen is why leak tests disagree.

After the browser is consistent

The checks above are this browser, this moment. Another application on the computer can still leave through the home connection. A game, a messenger, a launcher with no proxy field: the profile you just checked does not cover them.

That is the proxy client's job. The 2027 comparison of proxy clients is the list for that, with the checks as one of the things a client should let you prove. The download, when the apps outside the browser are the actual problem, is ProxyTool.
