About

Automatic VPN leak testing: all checks run on page load. Tests your public IP, DNS behavior (DoH), WebRTC ICE candidates, DNSSEC validation, geolocation, and browser privacy headers.

Built by SamNet.

How it works

1. Public IP — Detected via same-origin endpoint, then verified against Cloudflare CDN trace and external resolver.
2. WebRTC — Gathers ICE candidates via STUN to check if your real IP leaks through WebRTC.
3. DNS (DoH) — Queries Google & Cloudflare DNS-over-HTTPS to see what IP they resolve for you, plus DNSSEC validation.
4. Geolocation — Shows country from Cloudflare trace + city/ASN from external API.
5. Privacy Score — Aggregates all results into a 0–100 score.

All tests run automatically on page load. Click Run All Again to re-test.

Terms & Privacy

This tool automatically contacts the following services when the page loads:

• Same-origin: /api/whoami, /cdn-cgi/trace
• Third-party:
  • api.ipify.org (external IP verification)
  • dns.google & cloudflare-dns.com (DoH + DNSSEC)
  • api6.ipify.org (IPv6 connectivity check)
  • stun.l.google.com (WebRTC STUN)
  • ipapi.co (geolocation)

Your browser connects directly to these services; their privacy policies apply. All processing happens client-side.
