What your browser actually does.

Eight live checks against your current browser session — egress IPs, WebRTC, DNS resolver, TLS version, clock skew, cookie posture. Everything runs in this tab. Nothing is saved server-side.

1. EGRESSIPv4 egress address
2. EGRESSIPv6 reachability
3. LEAKSWebRTC IP leak
4. RESOLUTIONDNS resolver fingerprint
5. TRANSPORTTLS version in use
6. TRANSPORTHTTP protocol
7. POSTUREClock skew
8. POSTUREThird-party cookie posture

↳ All probes run in your browser tab. The clock-skew check pings /api/time on this site — no leak. WebRTC uses Google's public STUN to discover ICE candidates.
