ANTIDETECT
An antidetect browser is for cases where you need to run several accounts from one computer and you’d rather the platform didn’t link them together. Affiliate networks, social media, ad accounts, marketplaces — anywhere multi-accounting earns you a ban.
The subject is buried in myths. Some people think it’s a magic «now you can’t see me» button. Others install one and still catch bans, because what gives them away is something else entirely. Let’s go through what it actually does and what it doesn’t.
An antidetect browser doesn’t hide you. It makes your profiles look like different people.
Why you’d need one at all
Any site sees far more about your browser than you think. Not just the IP and the user agent, but dozens of parameters that add up to a fingerprint. It comes out so detailed that two identical ones are almost unheard of.
From there the platform’s logic is simple: five accounts logging in from the same fingerprint means one person. Then comes the ban or the shadow restrictions. And often the ban doesn’t land immediately but a week or two later, once the system has gathered statistics. That’s why people never understand what they got hit for.
An antidetect browser solves exactly that: every profile gets its own identity — its own set of parameters, its own cookies, its own cache, its own proxy. To the platform these are different computers belonging to different people.
What a fingerprint is made of
To understand what you’re paying for, it helps to know what actually gets spoofed. Here are the main things you’re identified by:
A «strange» fingerprint is less dangerous than a contradictoryone. A profile with macOS in the user agent but Windows fonts and a Moscow time zone — that is what raises questions. The goal isn’t to hide everything, it’s to look like an ordinary but different person.
What an antidetect browser doesn’t do
This is the honest part, the one the ads for these browsers leave out.
- It doesn’t save you from behavioral analysis. If five «different people» log in within the same minute, perform identical actions and type at the same speed, fingerprints won’t help.
- It doesn’t fix bad proxies. A cheap datacenter IP gives itself away instantly, no matter how perfect the fingerprint sitting on top of it.
- It doesn’t cancel account-level links. The same phone number, the same email, the same payment details link profiles more reliably than any canvas hash.
- Most solutions don’t patch the browser engine itself. The spoofing runs as scripts on top of ordinary Chromium. Against analytics and trackers that’s enough; against serious anti-fraud systems it’s a matter of luck.
What to look for when choosing
- Physical isolation of profiles. Every profile should have its own folder with cookies and cache, not just a «clear everything» between sessions.
- A persistent fingerprint. A profile has to look the same on every launch. If it’s one graphics card today and another tomorrow, that’s worse than spoofing nothing at all.
- Consistency between parameters. Check it on any fingerprint-testing service: if the system reports macOS while the fonts and codecs are from Windows, the solution is half-baked.
- Proxy support out of the box. Including username and password authentication and a check of the real IP, not just «connection established».
- No traces of automation. Many solutions drive the browser through the debug protocol, and that alone is visible to the site. Checked in one line: navigator.webdriver has to be false.
How to check that it all works
Don’t trust the description on the developer’s site — check it by hand. The scheme is simple:
- Create two profiles with different settings and open a fingerprint-testing service in each. The values have to differ.
- Close the profile and open it again. The values have to stay exactly the same.
- Check that the IP is detected as the proxy address rather than your home one, and that the time zone matches the proxy’s country.
- Check for a WebRTC leak separately — it turns up even in paid solutions.
When we were building our own antidetect browser, the very first test showed something easy to miss: we spoofed the graphics card name and left the list of its capabilities from the real one. That produced a contradiction inside a single fingerprint — which is worse than spoofing nothing at all. Real detection scripts look for exactly those discrepancies.
What we use ourselves
We ended up writing our own antidetect browser — Mirage. Not because there are no ready-made ones, but because we wanted to understand what happens under the hood and stop paying monthly for something we use every day.
Inside: a separate profile folder for every account, fingerprint spoofing through an extension instead of the debug protocol (so the browser stays an ordinary browser), a deterministic identity derived from a permanent profile key, proxies with a real IP check, and mobile profiles with genuine phone screen resolutions.
And an honest boundary stated up front: this is a layer on top of Chromium, not a rewritten engine. It works against trackers and ordinary analytics; against the most serious anti-fraud systems nobody can give you guarantees — including the people charging money for it.
Common mistakes
- Buying an antidetect browser and routing every profile through one proxy. That defeats the whole point.
- Registering accounts in a batch in one evening. The platform looks at creation time no less than at fingerprints.
- Logging into a «clean» profile from your normal browser first and only then from the antidetect one. The link has already been made.
- Giving every profile the same «nice» settings — top-end graphics card, 32 cores, a 4K screen. A combination that rare stands out by itself.
- Forgetting the time zone and the language. A profile «from the USA» running on Moscow time is a ready-made reason for a review.
We built our own antidetect browser, so we know where all of them are thin.
