BrowserLeaks is a free, browser-based diagnostic suite that systematically probes every available JavaScript API, browser feature, and network behavior to reconstruct the full fingerprint your browser exposes to the web.
Free browser fingerprint test with 35+ real-time checks. Detect WebRTC leaks, DNS leaks, canvas & WebGL fingerprinting, IP tracking, and bot detection.
Network leak checks IP, DNS, and WebRTC checks contact the BrowserLeaks.io API so the service can report what is visible outside your browser.
The main tools for checking IP address privacy. Showing Your IP Address, Reverse IP Lookup, Hostname, and HTTP Request Headers, Your Country, State, City, ISP/ASN, and Local Lime, Whois Lookup, TCP/IP OS fingerprinting, WebRTC Leak Test, DNS Leak Test, and IPv6 Leak Test.
Test Hub Privacy Leak Tests Choose a lab to validate network exposure, fingerprint uniqueness, and real-time communication leaks. Fingerprint checks run in your browser; network tests contact the BrowserLeaks service to measure what the internet can see.
BrowserLeaks.com is a website that provides a suite of tools that assess the security and privacy of your web browser. The tools are designed to test for various vulnerabilities that websites may exploit to gain access to your personal information.
The DNS Leak Test is a tool used to determine which DNS servers your browser is using to resolve domain names. This test attempts to resolve 50 randomly generated domain names, of which 25 are IPv4-only and 25 are IPv6-only.
JavaScript and Web APIs can provide vast amounts of data about the user's system, including User-Agent, screen resolution, system language, local time, CPU architecture, logical core count, battery status, network information, and installed plugins.
Run an IP leak test (via tools like browserleaks.com or Gologin’s built-in checker) to verify that your WebRTC, DNS, and IP match your spoofed location exactly.
