What is an antidetect browser? How it works, what it costs, and the rules that still apply
What antidetect browsers do, who uses them, what they cost, how to set up a profile properly, and why they don't make an account the rules forbid any safer.
The FingerBrowser team Updated 9 min read
An antidetect browser lets one person run many separate browser identities on one computer. Each identity, called a profile, has its own cookies, its own fingerprint and usually its own IP address, so a website sees each profile as a different device.
This guide explains how that works, who uses these tools and for what, what they cost, how to set up a profile properly, and what they can’t do: an antidetect browser changes what a website sees, not what its rules allow.
The short version
- An antidetect browser keeps many profiles apart. Each has its own cookies and storage, a stored browser fingerprint and, usually, its own proxy.
- They are sold for managing many accounts: social media agencies, online sellers, ad verification and testing. They are also used for fraud and ban evasion, and security companies treat them as fraud tools.
- Most are cheap to try. Of the 55 products in our directory, 40 have a free plan, typically with 2 to 5 profiles, and many paid plans start at $10 a month or less.
- The most important setup rule is consistency: each profile’s time zone, language and location should agree with its IP address, and stay the same every time.
- They don’t change platform rules. X, Instagram, Amazon and Mercari all limit multiple accounts in writing, and they link accounts through phone numbers, payments and behavior, not just the browser.
What is an antidetect browser?
An antidetect browser is a browser, usually built on Chromium or Firefox, with a profile manager in front of it. You create profiles, and each one opens as an isolated browser window. They are also called fingerprint browsers (the usual name among Chinese vendors) or multi-account browsers. The mobile equivalent is a cloud phone: a remote Android device you control from your computer, with its own apps, accounts and network.
What each profile keeps separate:
| Layer | What a profile has of its own | Why it matters |
|---|---|---|
| Storage | Cookies, local storage, cache, saved logins | Websites can’t see the other profiles’ sessions |
| Fingerprint | Operating system, screen, GPU, fonts, canvas and audio values, language, time zone | The device looks different to scripts that fingerprint it |
| Network | A proxy, so a different IP address and location | Accounts don’t share one connection |
| Extras | Extensions, bookmarks, open tabs | Each profile can be shared with a teammate or moved between computers |
Ordinary browsers already have profiles and private windows, but those only separate storage. Every Chrome profile on your laptop has the same fingerprint and the same IP address, so a website that fingerprints visitors can tell they are the same device. An antidetect browser separates all three layers.
How it works
Websites recognize a returning device in three main ways: cookies, the IP address, and the browser fingerprint, the combination of dozens of details such as screen size, graphics card, installed fonts, language and time zone. Our guide to browser fingerprinting explains the signals in detail.
An antidetect browser gives each profile its own version of each. The fingerprint part is the hard one. A profile has to report values that a real device could have, and every value has to agree with the others: a Windows user agent with a Mac GPU, or a Tokyo IP address with a New York time zone, stands out more than an ordinary browser would. Detection systems look precisely for these contradictions. That is why the better tools generate a complete, consistent device for each profile and then keep it stable, instead of randomizing values on every launch.
Who uses antidetect browsers
The people who use them openly fall into a few groups:
- Social media managers and agencies run accounts for several clients without logging out and in all day. X’s rules explicitly allow social media managers to control accounts on behalf of others.
- Online sellers with several legitimately separate businesses or brands keep each one’s marketplace and ad accounts apart.
- Ad verification and affiliate teams check what ads and landing pages look like from different countries and devices.
- Developers and QA testers test how a site behaves for users in other regions, languages or browsers, and test their own fraud detection.
- Privacy-minded users keep work, personal and research browsing from being linked.
The same features are useful for abuse: creating fake accounts, getting around bans, account takeover and payment fraud. Security researchers at Okta, for example, describe them as tools for using stolen login sessions while avoiding security controls. Treat that as context for how platforms see these tools, which is the subject of the rules section below.
What antidetect browsers cost
Prices are per profile or per number of profiles, billed monthly, with discounts for yearly billing. Across the 55 products in our directory, checked in October 2026:
- 40 have a free plan. Where the plan has a profile limit, it is usually 2 to 5 profiles. Others limit launches per day, end after a trial period, or are open-source tools with no limits and no support. Our list of antidetect browsers with a free plan shows each free plan’s limits.
- Paid plans start low. 16 of the 39 products priced in US dollars start at $10 a month or less, usually for 10 to 20 profiles. The cheapest entry plans cost a few dollars, and nearly all start at $99 or less; the exceptions are two engines built for large-scale automation, at $299 and $2,000 a month.
- Team seats, API access and cloud phones often cost extra. Cloud phones are usually billed per device or per minute of use.
The directory compares prices, free plans and user feedback for every product, and the comparison pages put two products side by side.
How to set one up
The details vary by product, but a sound setup follows the same steps:
- Choose by what you actually need: how many profiles, whether teammates need access, which operating system you use, and whether the app is available in your language. Try the free plan first.
- Create a profile and let the tool generate the fingerprint. Hand-editing individual values is the most common way to create contradictions. Change a setting only when you know why.
- Give each profile its own proxy, and match the profile to it. The time zone, language and geolocation should fit the proxy’s location. Most tools can set these from the IP address automatically.
- Check the profile from the inside. Open our browser fingerprint check in the profile. It shows whether the time zone, language, IP address and WebRTC agree with each other, which is what detection systems look at. To see whether two profiles look like the same device, compare them with the profile isolation check on the same page.
- Keep it stable. Use one profile per account, always with the same proxy, and don’t log the same account into several profiles.
Will it keep accounts from being banned?
Not by itself, and not when the account is one the platform’s rules forbid. An antidetect browser hides which accounts share a device. Platforms link accounts in many other ways: phone numbers, payment cards, bank accounts, shipping addresses, identity checks and behavior. In our directory, users of 20 of the 55 products report banned or restricted accounts.
The rules also matter more than the technology. Platforms publish them:
| Platform | What its rules say about multiple accounts |
|---|---|
| X | Up to 10 accounts for different, non-duplicative purposes are allowed, including social media managers running accounts for clients. Coordinated or duplicate accounts and new accounts to evade a suspension are prohibited, and X may suspend every account it believes the same person operates. |
| You can’t sign up if Instagram has previously disabled your account for breaking the law or its policies, and you can’t create an account for someone else without their permission. | |
| Amazon | Sellers may keep one Seller Central account per region unless they have a legitimate business need for a second, and all their accounts are in good standing. |
| Mercari (Japan) | An individual may not register more than one account. |
So the useful question is not whether a tool can hide a second account, but whether the second account is allowed. For an agency running clients’ accounts, or a seller Amazon has approved for a second account, a separate profile per account is good hygiene. For an account the rules forbid, the browser only delays the moment it is linked, and many platforms then suspend every linked account.
How to choose one you can trust
A profile holds logged-in sessions, and for many users, crypto wallet extensions too. That makes the vendor’s security as important as its features:
- In January 2025, attackers tampered with crypto-wallet extensions distributed through AdsPower, and about $4.7 million was reported stolen.
- In August 2023, BitBrowser said attackers had breached its server-side cache, and users who synced wallet extensions were told to move their funds.
- In July 2022, Dolphin Anty disclosed a leak affecting about 15% of browser profiles.
Each product page in our directory lists incidents like these with sources, along with recurring complaints about billing, support and bans. Look at those before you move valuable accounts into any tool, and keep wallet extensions out of shared or synced profiles.
Frequently asked questions
Is an antidetect browser legal?
The software is sold openly by registered companies, and using it is legal in most countries. What can be illegal is what it is used for, such as fraud, impersonation or unauthorized access. Breaking a platform’s terms is a separate matter: it usually isn’t a crime, but it can cost you the account. This isn’t legal advice.
Is there a free antidetect browser?
Yes. 40 of the 55 products in our directory have a free plan, and several open-source projects are free with no limits. See antidetect browsers with a free plan.
How is it different from a VPN or incognito mode?
A VPN changes your IP address only. Incognito mode gives you a temporary, empty cookie jar. Neither changes your fingerprint, so a website can still recognize the device. An antidetect browser separates cookies, fingerprint and IP address for each profile.
Can websites detect an antidetect browser?
Sometimes. Detection systems look for profiles whose values contradict each other or don’t match any real device, and for traffic from known proxy and data-center addresses. A consistent profile on a clean connection is much harder to tell apart from an ordinary browser, which is why consistency matters more than any single setting.
