By using this free web tool, you can find out what your browser is exposing to the internet and correct fingerprint discrepancies before they result in bans.

We’ll go over what Browserleaks is, its main functions, how to use it efficiently, and how it stacks up against other browser fingerprint checkers in this article.

Lastly, we’ll demonstrate how using Browserleaks in conjunction with NodeMaven provides the best privacy protection.

What Is Browserleaks?

Browserleaks is an online privacy tool that makes public all the information a website can find about your browser, device, and connection.

It offers a full range of tests to examine your fingerprint, including headers, JavaScript environment, WebRTC, Canvas, and WebGL.

Whether you use an anti-detect browser, are a web scraper, an affiliate marketer, or are just concerned about your privacy, Browserleaks helps you learn about the digital footprint of your browser.

Use Cases: Who can Benefit from Testing for Browserleaks?

A wide range of professionals use BrowserLeaks:

• Browser users who use anti-detect software to check for fingerprint leaks
• Developers evaluating fingerprint spoofing
• Proxy users checking for IP leaks and WebRTC
• To establish cross-browser consistency, QA engineers
• The identification of browser tracking vectors by privacy advocates
• Researchers looking into methods for fingerprinting browsers
• Testing with automation engineers
• Puppeteer/Selenium fingerprints

Features of Browserleaks

Browserleaks provides more than a dozen privacy and fingerprinting tests. Each one focuses on demonstrating what websites can detect, even when you’re using sophisticated spoofing or proxy software.

WebRTC Leak Test

WebRTC is a real-time communication protocol that is integrated into browsers. This section determines whether your real IP is leaking through it. Those who use a proxy or VPN and want to make sure that only the proxy IP is visible will find it particularly helpful.

WebGL & Canvas Fingerprint Recognition

Websites use WebGL and Canvas to create distinct visual hashes of your device’s rendering configuration and GPU. Browserleaks highlights the distinct fingerprint that your browser creates when it draws shapes or 3D content.

Details of the JavaScript Environment

Browserleaks checks your screen size, languages, time zone, user agent, JavaScript environment variables, and more. Frequently, these values are merged to create a fingerprint that can be used to identify or track your browser.

Geolocation and IP Address Visibility

Your detected IP address, hostname, ISP, and geolocation will all be displayed in this section. This is helpful for confirming that your proxy or VPN configuration is adequately anonymising you.

TLS Headers and Fingerprinting Details

Cipher suites and extensions, among other Transport Layer Security (TLS) configurations, can act as distinguishing markers. Browserleaks displays your HTTP headers, connection behaviours, and TLS client hello details.

How to Review Your Online Fingerprint Using Browserleaks

Although Browserleaks is easy to use, it can make a big difference if you read its output carefully. To begin, follow these steps:

Step 1: Visit the Browserleaks

Use the browser you wish to test to go to browserleaks.com. Extensions and downloads are not necessary.

Step 2: Select the appropriate test (WebRTC, Canvas, etc.).

The fingerprinting test categories include WebRTC, Canvas, WebGL, Fonts, Headers, and more. Click on any of them from the menu. The values that your browser exposes will be visible to you immediately.

Step 3: Examine the Findings and Their Significance

Verify if any of the values correspond to the profile you intended to spoof. You have an issue, for instance, if your WebRTC displays your actual IP address even though you are using a residential proxy.

Step 4: Optimize Browser Settings or Proxy Configuration with the Data

Use the findings to improve proxy settings, tweak fingerprint spoofing strategies, or fine-tune your anti-detect browser profiles. Continue until your fingerprints appear seamless and unblemished.

Browserleaks vs Different Browser Fingerprint Checkers

Although technical users and privacy enthusiasts frequently choose Browserleaks, there are other browser fingerprint testing tools out there.

This section will contrast Browserleaks with three noteworthy substitutes, each of which has unique fingerprint auditing advantages and disadvantages: Pixelscan.net, CreepJS, and Whoer.net.

Browserleaks vs Pixelscan.net

Pixelscan.net’s intuitive user interface and real-time evaluation results have made it a favorite among affiliate marketers, proxy users, and anti-detect browser testers.

Key Features:

• Real-time fingerprint scoring system (indicators of success or failure)
• Inconsistencies are highlighted (for example, the timezone does not match the IP geolocation).
• Gives a summary report on the quality of the browser configuration.
• WebRTC leak checks and real-time IP detection
• Evaluation of JavaScript fingerprinting

Use Cases:

• Protect against browser users testing fake profiles (e.g., GoLogin, Multilogin)
• Affiliate marketers verifying consistency prior to account launch
• Proxy testers confirming the absence of IP leaks

Pros:

• A simple scoring system
• Checks in real time with useful feedback
• Modern, sleek user interface
• Excellent for testing various browser profiles in bulk.

Cons:

• Less specific than browser leaks in HTTP headers, TLS, or environment variables in JavaScript
• No in-depth analyses of the unprocessed fingerprint data
• Not able to replicate behavioural fingerprinting

Pricing:

• Free to use
• There are rumors that a premium version for bulk testing and account-based tools is being developed.

Verdict:

Pixelscan is great for rapid diagnostics and high-level validation, especially for operational teams that need a “green light/red flag” check right away. But for more in-depth technical audits and debugging, Browserleaks offers more detailed information.

Browserleaks vs CreepJS

CreepJS is an extremely sophisticated fingerprint inspection tool designed to look like what contemporary anti-fraud software and fingerprinting suppliers actually find. It offers far more hardware-level and behavioral insights than the majority of fingerprint testers.

Key Features:

• Mouse movements, click events, and typing delays are examples of behavioural fingerprinting simulation.
• Canvas, WebGL, WebRTC, TLS, AudioContext, Battery, and Bluetooth fingerprints
• Comparison with the “normal” fingerprints of well-known, reliable browsers
• Entropy scores for visual fingerprints (too generic/too unique)

Use Cases:

• Developers creating automated anti-detect tools
• Security researchers are auditing systems for detecting bots
• Testing the appearance of human-like browser behaviour by QA engineers
• Expert proxy users confirm the randomness of fingerprints

Pros:

• Incredibly thorough, including behavioural simulation
• Incorporates entropy scoring for analysis of uniqueness.
• Knowledgeable in creating browser emulation or spoofing-resistant bots

Cons:

• Too much to handle for novices or casual users.
