Top 9 Checkers for Anti-detect Browsers

AUGUST 9, 2024 • PRIVACY & ANONYMITY • EXPERT OPINION

The Octo Browser Team constantly monitors how anti-fraud systems on popular websites evolve. Thanks to this, our digital fingerprint spoofing quality remains top-notch, allowing our users to engage in multi-accounting without the risk of being banned. One of the indicators of high-quality fingerprint spoofing is successfully passing checker tests. With default settings, Octo successfully handles popular checkers like Browserleaks, PixelScan, Whoer, and even newer services like Botchecker.net and Fv.pro, which other anti-detect browsers have yet to conquer. This article will explain how checkers work and discuss the nine most well-known ones.

A checker is a specialized online service that examines digital fingerprints and evaluates the effectiveness and reliability of anti-detect browsers. To do so, checkers analyze browser parameters and the data it sends to websites. Some services stop there; however, other checkers compare the obtained information with other available fingerprints, which helps them understand how unique a specific fingerprint is. Then they generate a report highlighting any discrepancies or vulnerabilities in the browser configuration, which allows users to decide whether to trust a particular anti-detect browser.

Browserleaks is known for its versatility. The site offers tests for browsers and devices, including geolocation, battery status, fonts, WebGL, Canvas, and also checks for WebRTC leaks. The latter helps determine if proxies and VPNs are working correctly. Additionally, Browserleaks provides detailed reports on IP addresses and ISPs. The site attracts around 900,000 visitors per month.

PixelScan primarily evaluates how realistically various digital fingerprint settings look taken together. Brief reports highlight suspicious fingerprint parameters that can help identify potential vulnerabilities. The service also displays all browser and device parameters that are visible to websites. This feature allows users to see if fingerprint parameters have been successfully updated after multi-accounting browser profiles have been changed. PixelScan recently added a proxy checker that functions as a Firefox extension. The site receives approximately 45.6 thousand visitors per month.

Botchecker helps you assess how trustworthy your digital identity appears. The service determines whether anti-fraud systems on popular websites can detect that you are using a proxy, an anti-detect browser, or browser automation via CDP and third-party libraries like Puppeteer, Playwright, and Selenium. Botchecker analyzes your IP address, operating system, and browser versions. You can also view specific device parameters, such as RAM size and the number of CPU cores, user agent, screen resolution, and the number of installed fonts. Additionally, the service identifies hashes and parameters related to location, languages, and time.

Like other checkers, fv.pro analyzes OS, user agent, screen resolution, location, time zone, and languages. Unlike many other sites, this tool also scans open ports. Users can also view WebGL, Canvas, Audio, and font hashes. The reports highlight discrepant parameters in red so users can correct them promptly. The site also offers an extended report, which may differ from the brief one.

Whoer offers comprehensive testing for DNS leaks, port scanning, and fingerprint detection on social media. The site also determines real and system time, location, languages, screen characteristics, operating system, and user agent. Like PixelScan, this checker can find errors and inconsistencies in the fingerprint.

AmIUnique analyzes the visitor's device fingerprint and compares it to 2 million fingerprints in its database. Then, the service calculates the percentage of users with the same value for each parameter and determines if your fingerprint can be considered unique overall. The site analyzes 57 parameters, including user agent, time zone, languages, fonts, plugins, screen resolution, screen depth, battery level, WebGL, Canvas, and Audio. You can view the uniqueness of all settings for today, a week, two weeks, a month, a quarter, and all time. Approximately 161.8 thousand people visit the service monthly.

As its name suggests, the site analyzes privacy. The service identifies the IP address, logged-in social media accounts, browser window resolution and color depth, time, language, and WebGL. Like AmIUnique, Privacy.net calculates the percentage of users with the same fingerprint parameters as yours. However, as it does not highlight discrepancies, it is inconvenient for checking anti-detect browsers.

In terms of its functionality and interface, the service is very similar to PixelScan. It checks whether your digital fingerprint raises websites’ suspicions. IPhey analyzes your browser version, user agent, geolocation, IP address, time zone, languages, fonts, WebGL, Canvas, Audio, and Client Rects.

The site provides users with comprehensive information about their devices. For example, the service identifies the type of device, its operating system, media devices, GPU type and model, RAM and storage capacity, battery level, Bluetooth availability, and fonts. The site can even determine whether you use a mouse or a touchpad. Additionally, DeviceInfo checks all standard fingerprint settings and can tell if you are using a proxy, VPN, or TOR.
