What Is BrowserLeaks.com?
BrowserLeaks.com is a free browser fingerprint diagnostic tool built by security researcher Taras. It doesn’t provide a privacy score or conceal the details behind green checkmarks. Instead, it dumps everything your browser reveals, so you can see the leaks for yourself.
Unlike “what’s my browser” sites, BrowserLeaks focuses on the technical signals that trackers combine to create a unique fingerprint. These include:
- Canvas and font rendering hashes
- GPU model and WebGL renderer
- WebRTC IP leaks
- Timezone, language, and geolocation coherence
- Hardware and JavaScript environment details
For anti-detect browser users, this level of transparency is essential. It will immediately expose if:
- Your spoofing produces identical hashes across profiles
- Your VM usage is visible in GPU or system details
- Your real IP is leaking through WebRTC
- Your timezone, language, and IP don’t align naturally
Why Use BrowserLeaks with Incogniton?
When you build a profile in Incogniton, you’re shaping a new browser identity, down to IP, timezone, WebGL, and language. BrowserLeaks acts as the microscope to examine whether that identity looks natural or suspicious from the outside.
Together, they give you a powerful feedback loop:
- Incogniton creates isolated, configurable profiles
- BrowserLeaks reveals hidden leaks or inconsistencies
- You adjust settings until the profile passes realistic fingerprint checks
This makes it possible to run multiple accounts, campaigns, or research projects without tripping detection systems.
When to Run a BrowserLeaks Test
BrowserLeaks is most valuable when you:
- Create a new profile (check it before first use)
- Change spoofing settings (canvas, WebGL, audio, timezone, etc.)
- Prepare to log into high-risk platforms (Google Ads, Meta, Amazon, LinkedIn)
- Investigate bans, flags, or unusual account linkages
How to Run a Full BrowserLeaks Audit
1. Prepare Your Profiles
Open or create the profiles you want to test in Incogniton and set IP, timezone, language, and hardware parameters for each.
2. Visit Each Test Page
Key URLs to check are Canvas, WebGL, WebRTC, IP and JavaScript.
3. Record Results
Use a spreadsheet to log hashes, GPU strings, IPs, and settings per profile.
4. Compare Across Profiles
Look for repeated hashes, mismatched geolocation data, or VM fingerprints.
5. Adjust and Retest
Tweak settings in Incogniton until each profile has a distinct, realistic fingerprint.

Frequently Asked Questions
Is BrowserLeaks.com free?
Yes. It’s a public tool. You do not have to subscribe, pay a fee or set up an account, or download a software file to use it.
Does BrowserLeaks.com store my fingerprint data?
No. According to the site’s privacy approach, all tests are run locally in your browser, and the data is not stored on their servers.
Can BrowserLeaks.com help me hide my fingerprint?
Not directly. It’s a testing tool, not an anti-detect or privacy tool. However, it can help you verify whether your current setup (e.g., VPN, anti-detect browser, or privacy extensions) is working as intended.
Who should use BrowserLeaks.com?
Anti-detect browser users, affiliate marketers, social media managers, penetration testers, journalists, OSINT researchers—anyone who needs to manage or protect their online identity.
Which browsers work with BrowserLeaks.com?
BrowserLeaks.com works on most modern browsers, including Chrome, Firefox, Safari, Edge, and privacy-focused browsers like Brave.
Will BrowserLeaks.com tell me if I’m 100% anonymous?
No. No tool can give you a “100% anonymous” score. Instead, it will show you what data you are leaking so you can take steps to minimize your fingerprint.
How does browserleaks.com compare to other tools like Pixelscan.net or Whoer.net?
BrowserLeaks.com is more of a raw, technical diagnostic tool with minimal UI, while tools like Pixelscan and Whoer.net offer more user-friendly scoring systems and consolidated results.
How often should I run tests on BrowserLeaks.com?
Run a test whenever you change your browsing setup—such as switching browsers, adding new privacy extensions, or configuring an anti-detect tool—so you can verify the changes are effective.
Can I use BrowserLeaks.com on mobile devices?
Yes, it works on mobile browsers too, though some fingerprinting elements may display differently compared to desktop.
Why do fingerprint test results differ between sites?
There are different methods of fingerprinting, and most websites use a different assortment of these methods. Some focus on JavaScript data, others on HTTP headers or network details. Also, VPNs, proxies, extensions, and IP reputation lists can also cause variations.
Do extensions affect your browser fingerprint?
Extensions can help block fingerprinting, but they can also make you more trackable. Some block certain scripts—reducing the amount of data collected—but also leave obvious gaps that make you stand out. Others add unique headers or modify your browser behaviour in detectable ways.
