BrowserLeaks — Privacy & Fingerprint Scanner

BrowserLeaks is a free privacy and security lab that runs entirely in your browser. See what websites, advertisers, and trackers can learn about you—before someone else does. Run deep fingerprint and leak checks in one place: WebRTC and DNS leaks, canvas, WebGL, audio, and font fingerprinting, IP and connection details, timezone and language signals, Client Hints, HTTP headers, bot detection, and more. Each test is built to show real, live results from your current session—not generic guesses. Whether you’re hardening your browser, comparing VPNs, auditing a privacy setup, or just curious what your “digital fingerprint” looks like, BrowserLeaks gives you clear, actionable insight. No account required to explore the core tools. Beyond leak tests, you get practical utilities: IP lookup, port scanner, password and hash tools, JWT decoder, regex tester, JSON formatter, and a full AI toolkit for SEO, robots.txt, schema, meta tags, and developer workflows—still focused on privacy, transparency, and the open web. Open BrowserLeaks from Chrome’s side panel and keep the full experience one click away while you work, research, or troubleshoot—same site, same depth, always up to date.
