BrowserLeaks is a suite of tools that offers a range of tests to evaluate the security and privacy of your web browser. These tests identify ways websites may leak your real IP address, collect information about your device, and perform browser fingerprinting. This website is a valuable resource for those prioritizing online security and privacy. It provides guidance on configuring their browsers to minimize the risk of personal information leaks.

Key Features

Tools for checking IP address: Tools for assessing IP address privacy reveal the user’s IP address, perform reverse IP lookups, and analyze HTTP request headers. This information can pinpoint the user’s location (country, state, city), ISP/ASN, and local time. Advanced features often include IP address whois lookups, TCP/IP OS fingerprinting, WebRTC, DNS, and IPv6 leak tests.
WebRTC leak test: The WebRTC leak test reveals the user’s real local and public IP addresses, even when using a VPN, proxy server, or behind a NAT. This tool can help verify whether a real public IP is being leaked.
WebGL report: The WebGL Report is a diagnostic tool that assesses your browser’s WebGL support. It generates a unique WebGL Fingerprint, which can potentially identify your specific browser.
Canvas Fingerprinting: Canvas fingerprinting generates a fingerprint based on the rendering characteristics of your browser by using HTML5 Canvas code.
Font Fingerprinting: Font fingerprinting tracks online activity by analyzing the unique characteristics of a user’s system fonts to create a unique fingerprint that is resistant to spoofing or alteration.
SSL/TSL client test: Checks your browser’s supported TLS protocols, cipher suites, TLS extensions, and key exchange groups. Identifies weak or insecure options, generates a JA3 TLS fingerprint, and tests how the browser handles insecure mixed content.
