WebRTC leak test
Your VPN can be connected and still leak your real IP through your browser. This checks for that in a couple of seconds — entirely in your browser, nothing sent or stored.
Runs locally · no sign-up · nothing logged
The test runs in your browser and only talks to a public STUN server to discover what your connection exposes. We don’t log or store your IP.
A good VPN closes this gap.
Reputable VPNs block WebRTC and DNS leaks by default. If this test flagged your real IP, that’s exactly what the right VPN prevents.
Frequently asked questions
What is a WebRTC leak?
WebRTC is a browser feature for real-time audio and video. To connect peers it can ask your network for your IP address — and in some setups it reveals your real IP even while a VPN is active, because it bypasses the normal connection.
How do I fix a WebRTC leak?
Use a VPN that explicitly blocks WebRTC leaks (most reputable ones do), enable its leak-protection setting, or disable WebRTC in your browser or with a trusted extension. Re-run this test afterwards to confirm.
Does “no leak” mean I’m anonymous?
No. It only means WebRTC isn’t exposing a separate IP. Full privacy also depends on DNS, your VPN’s no-logs policy, and good account security.
