About BrowserLeaks

BrowserLeaks is a collection of browser privacy tests. It shows your IP address, reverse lookup, HTTP headers, location and ISP, and runs WebRTC, DNS and IPv6 leak tests plus TCP/IP OS fingerprinting. JavaScript tests list what sites can read, such as user agent, screen resolution, language, CPU cores and battery status, alongside fingerprinting checks.

It suits VPN users confirming their real IP is hidden and anyone tuning browser privacy settings.
