Antidetect browsers: what they are, how they work and how to choose
Published · 2 min read
An antidetect browser lets you run many separate browsers on one computer, each with its own digital identity. On its own it's not enough, though: without a proxy every profile exits from the same IP.
What an antidetect browser is
It's a browser, usually based on Chromium or Firefox, that creates isolated profiles. Each profile has its own cookies, history, local storage and above all its own fingerprint: the set of traits websites use to recognise a device even without cookies.
To a website, two profiles from the same antidetect tool look like two different computers. That's why agencies, marketing teams and e-commerce businesses use them to manage multiple accounts while keeping them apart.
What makes up a browser fingerprint
- Declared user agent and operating system.
- Screen: resolution, colour depth, pixel density.
- Canvas and WebGL: tiny differences in how the graphics card draws images.
- Installed fonts and audio (AudioContext).
- Browser language, timezone and location.
- Hardware: number of cores, memory, media devices.
- WebRTC: can reveal local or real IP addresses if not handled.
A good antidetect tool doesn't generate random values but realistic combinations: an odd-looking fingerprint is as suspicious as a repeated one.
Why you also need a proxy
The antidetect tool separates devices, but the connection is still yours. If every profile exits from the same IP, websites can link them anyway. That's why each profile has a proxy field: enter the host, port, username and password of a proxy dedicated to that profile.
The strongest combination is an antidetect profile with a mobile proxy in the same country, language and timezone set from the IP, and the operating system matching the proxy's TCP/IP fingerprint.
The most popular ones
They all do the same basic job; interface, team features, automation and pricing differ. Plans and features change often, so always check the official websites.
| Tool | Strengths | Guide |
|---|---|---|
| AdsPower | Simple interface, no-code automation, team management | Set up AdsPower |
| Multilogin | One of the longest-running, two engines (Chromium and Firefox) | Set up Multilogin |
| GoLogin | Easy to start, cloud profiles too | Set up GoLogin |

How to choose
- How many profiles you need: plans differ mainly by profile count.
- Do you work in a team? Look at profile sharing, roles and activity logs.
- Automation: if you need it, check support for Selenium, Puppeteer, Playwright or an API.
- Fingerprint quality: try a profile on fingerprint test sites and check it's consistent.
- Proxy support: HTTP and SOCKS5 with authentication, built-in proxy check.
Frequently asked questions
Is an antidetect browser legal?
Yes, it's software like any other. Use it within the law and the websites' terms: separating legitimate work accounts is a common use, fraud and spam aren't.
Can I use incognito mode instead of an antidetect browser?
No. Incognito clears cookies at the end of the session, but the device fingerprint stays the same and websites recognise it.
Which proxy type do I use in an antidetect browser?
HTTP or SOCKS5, whichever is set on the proxy. The differences are explained in HTTP vs SOCKS5.
