How an antidetect browser works
Each profile keeps its own cookies, cache, local storage and login state. This separation prevents one profile’s saved site data from appearing in another.
The browser also controls values used in browser fingerprinting, including the user agent, language, time zone, screen dimensions, fonts and canvas output. Good profiles keep these signals consistent. A profile claiming to run on Windows, for example, shouldn’t expose platform details that indicate macOS.
Antidetect browser vs incognito mode
Incognito mode usually discards session history, cookies and site data after all private windows close. It doesn’t normally change the fingerprint exposed to websites, and it doesn’t delete downloaded files or bookmarks you created during the session.
| Feature | Antidetect browser | Incognito mode |
|---|---|---|
| Profile storage | Separate, reusable profiles | Private-session data usually discarded after all private windows close |
| Fingerprint | Controlled or modified | Usually unchanged |
| IP address | Unchanged without a proxy | Unchanged |
A regular browser can also maintain separate profiles, but it usually reports the device’s actual browser attributes rather than presenting a configured fingerprint.
How antidetect browsers work with proxies
An antidetect browser and a proxy server handle different identity signals. The browser controls profile storage and fingerprint data. The proxy changes the public IP address that the website sees.
When binding a proxy to a profile, keep its location consistent with the profile’s time zone and language. Reusing one stable IP for a returning account is often less disruptive than changing it during a session. You should also test for a WebRTC leak, DNS behavior and mismatched browser headers.
Neither tool makes activity invisible. Websites can compare IP history, request timing, account behavior and JavaScript signals alongside the browser fingerprint.
Responsible use
- Follow site rules. Respect terms, account limits and access controls.
- Keep approved accounts separate. Use one profile for each authorized account to prevent cookies and sessions from mixing.
- Test localized experiences. Pair a profile and proxy to check regional pages, ads or application behavior.
- Inspect the software. Antidetect browsers handle credentials and cookies, so use trusted software and restrict access to profile data.
Don’t use profile isolation to create unauthorized accounts, bypass bans or defeat security controls.
FAQ
Does an antidetect browser hide my IP address?
No. It changes or controls browser-level signals, but your connection still exposes its public IP. You need a proxy or VPN to change the IP that websites see.
Is an antidetect browser the same as incognito mode?
No. Incognito mode mainly limits which session data remains after all private windows close. An antidetect browser manages separate profiles and controls fingerprint attributes exposed to websites.
Can websites detect an antidetect browser?
Yes. Sites may detect inconsistent fingerprints, unusual behavior or known modifications. No browser profile guarantees that a site will treat it as a normal visitor.
