WebRTC Leak Test
Inspect browser ICE candidates with a self-hosted STUN service.
How it works
Gather ICE candidates for up to five seconds through the configured self-hosted STUN server.
Privacy
Candidates are parsed locally and never sent to the SFranKey API. The STUN server naturally sees your source IP.
FAQ
Why do I see an mDNS name? Modern browsers use mDNS to protect local host addresses; the tool does not resolve it.
