An antidetect browser (also called a multi-accounting or anti-fingerprint browser) lets you run many completely separate browser profiles on one computer. Each profile has its own cookies, storage and its own unique browser fingerprint, so websites see each one as a different device.
The goal is multi-accounting: operating several accounts on the same platform without them being connected. Paired with a proxy per profile, every identity appears to come from a different device and a different location.
In one sentence
To understand antidetect browsers, you first need to understand fingerprinting. Every browser leaks dozens of small details about your device. Individually they're common, but combined they often form a unique signature — no cookies required. Some of the signals:
Techniques like canvas fingerprinting are especially sticky because they rely on hardware traits you can't easily change. That's exactly what an antidetect browser is built to control.
For each profile, the browser presents a different, internally-consistent set of fingerprint values and keeps cookies and storage fully isolated. Toggle below to see why that matters when running three accounts from one machine:
3 accounts, one machine
| Account 1 | Account 2 | Account 3 | |
|---|---|---|---|
| User agent | Chrome 128 · Win | Safari 17 · macOS | Firefox 129 · Linux |
| Timezone | UTC−5 | UTC+1 | UTC+9 |
| Screen | 1920×1080 | 1440×900 | 1366×768 |
| Canvas | a1b2c3… | c3d4e5… | e5f6a7… |
| WebGL | Intel | Apple | Mesa |
| IP address | 203.0.113.5 | 198.51.100.9 | 192.0.2.7 |
Without isolation, all three accounts share one fingerprint and one IP, so a platform can trivially link — and often ban — them together. With an antidetect profile plus a dedicated proxy, each account looks like a separate person on a separate device and network. Consistency is key: a mobile user agent paired with a desktop screen size is an instant giveaway, so good tools keep every value plausible.
These three get confused often, but they protect completely different things:
| Antidetect browser | Incognito | VPN | |
|---|---|---|---|
| Changes fingerprint | Yes, per profile | No | No |
| Isolates profiles | Yes | One at a time | No |
| Changes IP | Via a proxy | No | Yes |
| Encrypts traffic | No (proxy) | No | Yes |
| Best for | Multi-accounting | Not saving local history | Privacy & security |

They're a workhorse anywhere people legitimately manage many accounts or identities:
Affiliate & media buyers
Run multiple ad accounts to spread risk and test creatives.
Social media agencies
Manage many client accounts from one place without links.
Marketplace sellers
Operate several storefronts that platforms would otherwise ban.
E-commerce & retail
Handle regional accounts and limited-release purchasing.
Growth & research teams
Test flows and gather data across many isolated sessions.
Privacy-minded users
Compartmentalise identities so activity isn't cross-linked.
A unique fingerprint is only half the picture. If all your profiles share one IP address, platforms can link them by network just as easily as by device. That's why each profile is paired with its own proxy — usually a residential or mobile IP that looks like a real user.
The winning combination
The software is legal to own and use. The nuance is what you do with it: many platforms restrict operating multiple accounts in their terms of service, so multi-accounting can risk account suspension even where it isn't illegal. Plenty of uses — agency social management, regional e-commerce, ad operations, privacy compartmentalisation — are entirely legitimate.
Common myths, cleared up:
No. Incognito only avoids saving local cookies and history. An antidetect browser actively spoofs your whole fingerprint and fully isolates each profile — a completely different mechanism.
Not on its own. Different IPs still share one browser fingerprint, so platforms can link accounts by device. You need both a unique fingerprint and a unique IP.
They're a general multi-account tool used heavily by legitimate agencies, sellers and marketers. Like any tool, misuse is possible, but the technology itself is neutral.

Spinning up your first isolated profile is quick:
- 1
Create a new browser profile
In the antidetect browser, add a fresh profile for each account you want to keep separate.
- 2
Set a unique fingerprint
Auto-generate or fine-tune the profile's fingerprint (user agent, timezone, canvas, WebGL, fonts) so it's distinct and internally consistent.
- 3
Attach a dedicated proxy
Assign a residential or mobile proxy to the profile so it also has its own IP and location. One proxy per profile.
- 4
Launch and log in
Open the profile and sign into the account. Repeat per identity — each looks like a different person on a different device.

1 / 4What does an antidetect browser mainly do?
The software itself is legal. Whether a specific use is allowed depends on the platform's terms of service — many restrict operating multiple accounts — and on applicable law. Common uses like agency social media management and e-commerce operations are legitimate, but always check the platform rules.
A VPN encrypts your traffic and changes your IP for the whole device. An antidetect browser changes your browser fingerprint and isolates profiles so accounts don't get linked. They solve different problems — and are often used together (fingerprint isolation + a proxy per profile).
Almost always, yes. A unique fingerprint still shares a single IP address without proxies, and sites correlate accounts by IP too. Each profile is typically paired with its own residential or mobile proxy so every identity has a different IP and location.
Incognito mode only avoids saving cookies and history on your device for the session. It doesn't change your fingerprint, so sites still recognise the same device. An antidetect browser spoofs the whole fingerprint and keeps each profile fully isolated.
It depends on the tool and your hardware. Cloud-based options scale to hundreds of profiles, while locally-run profiles are limited by your machine's memory and CPU. Serious operators run dozens to hundreds in parallel.
It's a profile of your device built from many browser and hardware signals — user agent, screen size, fonts, timezone, and rendering quirks in canvas, WebGL and audio. Combined, they're often unique enough to identify one device even without cookies.
