What Is Browserleaks?

Browserleaks is a privacy-focused online tool designed to reveal everything a website can detect about your browser, device, and connection.

It provides a comprehensive suite of tests to inspect your fingerprint, including WebRTC, Canvas, WebGL, JavaScript environment, headers, and more. 

Whether you’re an anti-detect browser user, web scraper, affiliate marketer, or simply privacy-conscious, Browserleaks helps you understand your browser’s digital footprint.

Use Cases: Who Benefits from Browserleaks Testing?

Browserleaks is used by a wide range of professionals:

  • Anti-detect browser users checking for fingerprint leaks
  • Developers testing the effectiveness of fingerprint spoofing
  • Proxy users auditing WebRTC and IP leaks
  • QA engineers to create cross-browser consistency
  • Privacy advocates identifying browser tracking vectors
  • Researchers studying browser fingerprinting techniques
  • Automation engineers testing Selenium/Puppeteer fingerprints

Key Features of Browserleaks

Browserleaks offers over a dozen fingerprinting and privacy tests. Each one is dedicated to showing what can be detected by websites, even if you’re using advanced proxy or spoofing tools.

Key Features of Browserleaks

WebRTC Leak Test

This section checks whether your real IP is leaking through WebRTC (a real-time communication protocol built into browsers). It’s especially useful for proxy and VPN users who want to confirm that only the proxy IP is visible.

Canvas & WebGL Fingerprint Detection

Canvas and WebGL are used by websites to generate unique visual hashes of your device’s GPU and rendering setup. Browserleaks shows how your browser draws shapes or 3D content and flags the unique fingerprint it produces.

JavaScript Environment Info

Browserleaks scans your JavaScript environment variables, user-agent, screen size, languages, timezone, and more. These values are often combined into a fingerprint that can be used to track or identify your browser.

IP Address & Geolocation Visibility

In this section, you’ll see your detected IP address, hostname, ISP, and geolocation. This is useful for verifying that your proxy or VPN setup is properly anonymizing you.

TLS Fingerprinting and Headers Info

Transport Layer Security (TLS) settings like cipher suites and extensions can serve as identifying fingerprints. Browserleaks shows your TLS client hello details, HTTP headers, and connection behaviors.

How to Use Browserleaks to Audit Your Online Fingerprint

Browserleaks is simple to use, but reading its output properly can make all the difference. Here’s how to get started:

step by step guide on how to use browserleaks

Step 1 – Visit the Browserleaks Site

Head to browserleaks.com in the browser you want to test. No downloads or extensions are required.

Step 2 – Choose the Relevant Test (WebRTC, Canvas, etc.)

Click on any of the fingerprinting test categories from the menu: WebRTC, Canvas, WebGL, Fonts, Headers, and more. You’ll instantly see the values your browser exposes.

Step 3 – Analyze the Results and What They Mean

Check whether any values match your intended spoofed profile. For example, if you’re using a residential proxy but your WebRTC shows your real IP, you’ve got a problem.

Step 4 – Use the Data to Optimize Browser Settings or Proxy Setup

Use the results to fine-tune your anti-detect browser profiles, select better proxy configurations, or adjust fingerprint spoofing techniques. Repeat until your fingerprint looks natural and leak-free.

Pros and Cons of Using Browserleaks

Browserleaks is widely respected for its transparency and accuracy, but it’s not without limitations.

Pros

  • Completely free and open access
  • No signup or login required
  • Tests a wide range of fingerprint types
  • Offers advanced TLS and header inspection
  • Useful for both beginners and advanced users

Cons

  • No automated alerts or re-test scheduling
  • Doesn’t simulate behavioral fingerprinting

Browserleaks vs Other Browser Fingerprint Checkers

While Browserleaks is a popular choice for privacy enthusiasts and technical users, it’s not the only browser fingerprint testing tool available. 

In this section, we’ll compare Browserleaks against three notable alternatives: Pixelscan.net, CreepJS, and Whoer.net – each offering different strengths and limitations for fingerprint auditing.

Browserleaks vs Pixelscan.net

Pixelscan.net has become a favorite among proxy users, anti-detect browser testers, and affiliate marketers due to its user-friendly interface and real-time evaluation results.

Key Features:

  • Live fingerprint scoring system (Pass / Fail indicators)
  • Highlights inconsistencies (e.g., timezone doesn’t match IP geolocation)
  • Provides summary report for browser configuration quality
  • Real-time IP detection and WebRTC leak checks
  • JavaScript fingerprinting evaluation

Use Cases:

  • Anti-detect browser users testing spoofed profiles (e.g., Multilogin, GoLogin)
  • Affiliate marketers checking consistency before launching accounts
  • Proxy testers verifying that IP leaks aren’t present

Pros:

  • Easy to understand scoring system
  • Real-time checks with actionable feedback
  • Sleek, modern UI
  • Great for batch testing different browser profiles

Cons:

  • Less detailed than Browserleaks in TLS, HTTP headers, or JS environment variables
  • No deep breakdowns of raw fingerprint data
  • Doesn’t simulate behavioral fingerprinting

Pricing:

  • Free to use
  • Premium version rumored in development for account-based tools and bulk testing

Verdict:

Pixelscan is excellent for high-level validation and quick diagnostics, especially for operational teams who want an instant “green light/red flag” check. However, for deeper technical audits and debugging, Browserleaks provides more granular insights.

Browserleaks vs CreepJS

CreepJS is a highly advanced fingerprint inspection tool built to simulate what modern anti-fraud systems and fingerprinting vendors actually detect. It provides behavioral and hardware-level insights far beyond what most fingerprint testers offer.

Key Features:

  • Behavioral fingerprinting simulation (mouse movements, click events, typing delays)
  • AudioContext, Canvas, WebGL, WebRTC, TLS, Battery, Bluetooth fingerprints
  • Comparison with “typical” fingerprints from known good browsers
  • Visual fingerprint entropy scores (too unique / too generic)

Use Cases:

  • Developers building anti-detect automation tools
  • Security researchers auditing bot detection systems
  • QA engineers testing how human-like browser behavior appears
  • Advanced proxy users verifying fingerprint randomness

Pros:

  • Extremely comprehensive, including behavioral simulation
  • Includes entropy scoring for uniqueness analysis
  • Insightful for building spoofing-resistant bots or browser emulation

Cons:

  • Overwhelming for beginners or casual users
  • Limited documentation on some tests
  • Doesn’t include “clean pass/fail” results like Pixelscan

Pricing:

  • Open source and free to use
  • Hosted version available at creepjs.vercel.app

Verdict:

CreepJS is the go-to choice for hardcore developers and researchers looking to audit every detail of a browser’s fingerprint. Browserleaks, while also technical, doesn’t simulate user behavior and is better suited for traditional fingerprint layer diagnostics.

Browserleaks vs Whoer.net

Whoer.net is a more consumer-friendly fingerprinting and privacy checker that combines IP geolocation data with a basic fingerprint overview. It’s used by VPN customers, casual proxy users, and non-technical marketers.

  • VPN users checking their anonymity status
  • Light proxy users testing for IP/DNS/WebRTC leaks
  • Non-technical users wanting an overview of privacy exposure

Pros:

  • Very easy to use with no technical background
  • Includes VPN-specific detection score
  • Attractive dashboard and summary view

Cons:

  • Lacks advanced fingerprint tests (Canvas, WebGL, TLS, etc.)
  • No JavaScript environment or header info
  • Not suitable for automation, scraping, or anti-detect browser testing

Pricing:

  • Free version with basic features
  • Premium VPN product bundled with extra analytics and VPN servers (starting at ~$3/month)

Verdict:

Whoer.net is a great starting point for casual users, VPN customers, and those doing basic privacy checks. However, for serious fingerprint auditing or automation work, it doesn’t hold up against Browserleaks or more advanced testing tools like CreepJS or Pixelscan.

To conclude each tool serves a different type of user. If you’re doing casual checks, Whoer.net is plenty. If you want performance feedback and validation, Pixelscan is your ally. 

For in-depth, technical fingerprint debugging, Browserleaks is king. And for the deepest behavioral fingerprint simulation, CreepJS leads the pack. 

Ideally, using Browserleaks in combination with one of these tools provides the most comprehensive fingerprint strategy, especially when paired with quality proxies and anti-detect environments like NodeMaven.
