Question 1

What is an antidetect browser, and what problem does it solve?

Accepted Answer

When browsing with a standard browser, we not only reveal our IP address but also multiple signals, including screen resolution, installed fonts, time zone, language, operating system, hardware configuration, and cookies. Collectively, they form a device or client fingerprint (check yours at CoverYourTracks) that helps security platforms (e.g., Cloudflare and Akamai) tag and block/throttle workflows such as multi-accounting and web scraping. But an antidetect browser like AdsPower enables users to create distinct browser profiles, each having its own unique device fingerprint.

When coupled with a performant proxy such as Byteful, it enables a single user managing multiple ad/social/e-commerce accounts on a single device to obtain a separate client and network identity for each profile. This appears to be separate sessions coming from different real users to platforms like Google, Amazon, and Meta.

This profile isolation is what makes multi-accounting possible and is the unique selling point of anti-detect browsers. In its absence, platforms can link multiple accounts from a single environment and impose bans.

Question 2

How is an antidetect browser different from a VPN or incognito?

Accepted Answer

A VPN masks the IP address (much like a proxy) and adds data encryption, which means onlookers won’t see anything even if they could monitor a user’s web activity.   On the other hand, a browser’s incognito mode simply gives a fresh start every time a user opens a new incognito tab. It ensures it doesn't take anything from the existing browser history, cache, or cookies, and leaves no trace upon closure. Both address some privacy issues, but masking the client fingerprint isn’t one of them. A user can still be identified by a unique browser fingerprint, even when using a VPN or a browser in incognito mode, as mentioned in W3C’s fingerprint guidance document. This is because the device identifiers related to the software and hardware remain largely the same for both. However, an antidetect browser, when paired with a proxy, gives maximum protection against fingerprinting, making it a key necessity for multi-accounting.

Question 3

What separates a strong antidetect browser from a weak one?

Accepted Answer

There are multiple device identifiers, such as WebGL, canvas rendering, hardware details (monitor, CPU, RAM, & GPU), operating system, browser version and type, extensions, installed fonts, location, time zone, and more. A weak anti-detect browser uses conflicting values that hardly match any real users. For instance, using a Safari browser agent with the rest of a setup that looks like a Windows machine. Inconsistencies like these are easy for modern web defenses to pinpoint and end up doing more harm than good. Besides, using outdated browser code or the inability to patch WebRTC and DNS leaks are clear markers of a bad anti-detect browser. On the contrary, a good antidetect browser comes with an updated codebase that is natively modified to spoof device identifiers. Expect logically perfect alignment among different browsing signals and tight browser profile isolation (including separate cookies, local storage, and cache).  But the best anti-detect browsers are the ones that also address TLS fingerprinting (in addition to spoofing device and network identifiers), because the TLS handshake happens directly between the browser and the destination server (without any proxy intervention) and is increasingly being used by sophisticated security platforms.

Question 4

What are the best antidetect browsers, and who is each best suited to?

Accepted Answer

Adspower: It’s a beginner-friendly yet powerful anti-detect browser that is best known for its drag-and-drop workflows and no-code automation. It supports emulating popular browsers with its Chromium-based (SunBrowser) and Firefox-based (FlowerBrowser) browser engines. Though it doesn’t currently feature built-in proxies, it readily integrates with popular proxy providers such as Byteful, Oxylabs, and Brightdata.Dolphin Anty: This anti-detect browser offers five profiles for free users and packs a good deal into the paid plans, including local and cloud sync, Chrome & Firefox emulation, and extensive team collaboration capabilities. It allows you to filter profiles by platform (e.g., Facebook and TikTok), making it easy to work with hundreds of accounts. Dolphin Anty also rolled out automated browser scenarios (scripted automated actions), arguably the first in this industry to do so. And, as with its peers, integrating a proxy with Dolphin Anty is extremely straightforward.Kameleo: This one provides two custom browser engines, Chroma and Junglefox, to spoof Chrome and Firefox, respectively.  Kameleo’s Docker-ready deployment and SDK make it a developer-friendly anti-detect solution. It’s also one of the few providers that offers 100 cloud profiles (though with capped browser time) even with its free tier. Kameleo also comes with serious firepower for mobile fingerprinting, with its automatic kernel matching that helps auto-select the best Chroma engine based on the profile. Finally, integrating proxies with Kameleo is effortless with its built-in proxy manager.MultiLogin: It's core advertised USP is enabling access across multiple social platforms, and they openly claim to test it daily against 50+ platforms, including Amazon, X, Reddit, LinkedIn, TikTok, Snapchat, and more. You can use MultiLogin end-to-end for managing mobile app accounts, including for verification, logins, and posting, without having to use a physical device. But none of that works as expected without setting up a good proxy within MultiLogin. However, it’s one of the mainstream solutions that doesn’t offer a free tier. Instead, you have a 3-day trial for $2.GoLogin: It is a great choice for its reliability, as evident by its 99.99% historical uptime. It handles 50 device identifiers while keeping the multi-accounting data in its cloud, so your local hardware limitations don’t bottleneck at all. GoLogin also leads in managing multiple profiles and teamwork, with its granular per-profile access controls. Though it comes with built-in proxies, you can also have a custom GoLogin proxy setup. A minor downside is that it’s built around Chrome emulation, so there is no option to spoof a Firefox browser as of this writing.

Question 5

Is there a good free anti-detect browser, or do you have to pay?

Accepted Answer

There are multiple good anti-detect browsers that also offer free tiers. For instance, you can sign up for Dolphin Anty, GoLogin, and AdsPower for free.  However, the free tiers only suit someone at early stages, with very limited multi-accounting needs. Features such as team management, cloud sync, batch profile management, and API access are generally reserved for paid tiers. The most generous free tier is from GoLogin, where you can create three profiles and get to enjoy all premium features except profile sharing and team management.  AdsPower's free tier lets you create two profiles, but it lets you play with its synchronizer and RPA automation tool. On the other hand, Dolphin Anty offers five profiles on its free tier, but reserves many premium features, such as synchronizer and scenario builder, for its paid users. Finally, you can try Kameleo if free cloud profiles are on your radar.

Question 6

Why does an antidetect browser need a proxy to work?

Accepted Answer

An antidetect browser is a custom-built browser engine that helps emulate canvas hashes, WebGL rendering, timezone, language, fonts, operating system, and other parameters that security systems collect to build a device fingerprint.  However, network identity (primarily defined by the IP address) remains an independent detection vector that warrants attention. And since this is outside the scope of an anti-detect browser, one needs to plug proxies to cover that aspect for a coherent device+network fingerprint.  That said, proxy signals and device signals shouldn’t conflict. For instance, using a US -based residential proxy location with the timezone and location indicating a European country can still get the profile and IP banned.

Question 7

How do you switch antidetect browsers or move profiles without losing accounts?

Accepted Answer

A complete switch, including 100% of the fingerprinting parameters from one tool to another, is not practically possible because migration capabilities vary across providers. Therefore, you must confirm the extent of migration your existing tool supports before moving on to the next step. Remember that fingerprinting configuration, cookies, local storage, and settings are the most important parameters to export, along with the proxy configuration.  An abrupt switch affecting all profiles at once can also be a detection risk on its own. Therefore, even after confirming the import-export match, one must gradually migrate, starting with low-value profiles. Afterward, we recommend logging out of the old tool profile, one profile at a time, once you confirm the new setup is working.  Finally, manual transition can be tedious at scale. So, check if your anti-detect browser supports API-led migration.
