What is an antidetect browser?
- Websites identify your device by its fingerprint — screen, fonts, GPU, timezone — with no cookies needed.
- Platforms link accounts that share a fingerprint or an IP, which is why bans arrive in batches.
- An antidetect browser gives each profile a separate, consistent identity that persists over time.
- It only handles the device half. Each profile still needs its own proxy, or the shared IP links them anyway.
- Consistency beats concealment — contradictory values are far more suspicious than ordinary ones.
The everyday comparison is a set of separate laptops. If you genuinely had ten machines on ten different internet connections, no platform could tie those accounts together. An antidetect browser gives you that separation in software, on one computer.
Your fingerprint, right now
Read live from your browser, in your browser. Nothing here is sent anywhere.
Tap any row to see why that signal matters. “Rarity” is roughly how many bits of identifying information it contributes.
Bit values are indicative averages, not a measurement of your personal uniqueness. Everything is computed locally and discarded when you leave the page.
Why platforms link your accounts
Three accounts, one machine. Watch what the platform sees in each setup.
One person with three accounts — and it is obvious.
Identical fingerprint and identical IP across all three. Platforms match on exactly this, which is why a ban on one account so often takes the rest with it.
More detail in how social platforms detect multiple accounts.
How they actually work
Only one of them actually works for account management.
Every value agrees with every other and stays stable over time. The profile looks like one ordinary Mac user in New York — which is exactly the point.
What gives a bot away
These are the checks an anti-bot script runs in the first few milliseconds.
Set automatically by Selenium and Playwright unless patched. The single most checked flag.
Headless builds announce themselves in the UA string by default.
Real desktop browsers report plugins. An empty list is unusual.
Default headless viewport sizes are a giveaway.
Behaviour is checked as well as configuration.
Software rendering means no real GPU — almost always a server.
Relevant if you are running headless browsers or AI agents across many profiles.
A browser alone is not enough
A browser alone is half the job. Pick what you are doing and see the full setup.
Antidetect browser, one profile per account
Mobile proxies — a dedicated IP per account
Instagram and TikTok are the least forgiving platforms there are. Mobile IPs are shared with thousands of real subscribers, so they are the hardest to ban outright.
Who actually uses these
Agencies and ad buyers
One agency legitimately manages ad accounts for dozens of clients. Without isolation those accounts look like one operator gaming the platform.
E-commerce sellers
Running storefronts across several marketplaces and regions, each of which expects a seller to be a distinct business.
Ad verification
Checking that campaigns render correctly and are not being cloaked, which requires looking like a genuine local visitor rather than a monitoring bot.
Market and price research
Collecting competitor pricing and search results without being served a personalised or deliberately distorted view.
Security researchers
Investigating phishing kits and fraud infrastructure that behave differently for known security IPs and browsers.
AI agents and QA
Automated browsing at scale, and testing how a site behaves for many different device and locale combinations.
Six things that actually matter
Fingerprint quality
The values must be internally consistent and stable across sessions. Cheap tools generate combinations that never occur on real hardware.
How to chooseProfile management at your scale
Ten profiles is a UI problem; a thousand is a bulk-operations problem. Check import, tagging, and cloning before you commit.
Compare browsersTeam features
Sharing profiles with colleagues without sharing passwords, plus role permissions and an activity log. Essential for agencies.
Compare side by sideAutomation API
Programmatic profile creation and Playwright or Puppeteer hooks. Non-negotiable if agents or scripts will drive the browser.
Browsers for AI agentsCloud or local profiles
Cloud profiles sync across machines and teams; local ones keep data on your hardware. It is a genuine privacy-versus-convenience trade.
Multi-account browsersProxy integration
Per-profile proxy settings that are quick to assign in bulk. Fiddly proxy handling is where most of the day-to-day pain lives.
Proxies explainedFive mistakes that get accounts banned
- 1
Using distinct profiles from one IP address
The most common mistake by far. Ten perfect fingerprints arriving from your home connection are still one household. Every profile needs its own proxy.
- 2
Reusing a profile for two accounts
It recreates precisely the link you bought the software to avoid. One identity per profile, always.
- 3
Mismatching timezone, language and IP
A profile claiming Berlin while the IP is in Ohio and the language is en-GB is more suspicious than no protection at all. Match the whole persona.
- 4
Blasting a fresh profile with automation
New accounts behaving like power users on day one get caught regardless of fingerprint. Warm them up with ordinary activity first.
- 5
Assuming the browser does everything
It handles device signals. Behaviour, request timing, payment details and account history are all still visible — and all still matched.

Antidetect browser FAQ
1What is an antidetect browser?
It is a browser that runs many isolated profiles, each with its own fingerprint, cookies, storage and proxy. To a website, every profile looks like a separate person on a separate device — which is what lets you run several accounts without a platform linking them together.
2How is it different from incognito mode or a VPN?
Incognito clears cookies but keeps the same fingerprint, so you are still recognisable. A VPN changes your IP but not your device signals. An antidetect browser changes both, and keeps each profile consistent and separate over time.
3Why do my accounts get banned together?
Platforms match accounts on shared signals — the same IP address, the same browser fingerprint, the same cookies, sometimes the same payment details. If several accounts share those, a ban on one commonly takes the rest with it.
4Do I still need proxies if I use an antidetect browser?
Yes. The browser controls how your device looks; the proxy controls where you appear to be. Ten perfectly distinct profiles all arriving from one IP address are still obviously connected, so each profile needs its own IP.
5Are antidetect browsers legal?
The software itself is entirely legal and is used by agencies, e-commerce sellers, ad verification teams and security researchers. Using one to breach a platform’s terms of service is a separate matter — that is a contractual issue between you and the platform.
6Can websites detect an antidetect browser?
A poorly configured one, yes. The tell is inconsistency — a user agent claiming iPhone while WebGL reports a desktop GPU, or a timezone that contradicts the IP country. A well-built profile whose values all agree is very difficult to distinguish from an ordinary user.
7Is blocking fingerprinting scripts a better approach?
Usually not. A browser that refuses to answer these queries is itself rare, and rare is easier to track. The approaches that work are randomising the values or presenting a consistent, believable persona.
8How many profiles do I need?
One per identity you want kept separate — typically one per account on strict platforms like Instagram or ad networks. Sharing a profile between two accounts recreates exactly the link you were trying to avoid.
