BrowScan is a free browser privacy and security scanner. It shows what any website can learn about you — the real IP hiding behind your VPN, DNS and WebRTC leaks, and the fingerprint signals that make your browser identifiable — so you can harden your setup in seconds.
IP address & geolocation check
See the IPv4 and IPv6 addresses you actually expose, plus the country, city and ISP they map to.
DNS leak test
Find out whether your DNS queries escape your VPN or proxy and reveal your real location.
WebRTC leak test
Detect local and public IP addresses leaked through WebRTC even while a VPN is active.
Browser fingerprint analysis
Review canvas, WebGL, fonts, screen, timezone and hardware signals that make your browser stand out.
VPN & proxy detection
Check whether your VPN or proxy is actually recognised as such, or still giving you away.
