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

- 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.
