What Is a WebRTC Leak?
WebRTC (Web Real-Time Communication) is a browser technology for video calls and peer-to-peer connections. It requires your real IP to establish connections — and can bypass your VPN tunnel, exposing your true IP to any website.
This tool tests your browser against 12 major STUN servers simultaneously — the same servers used by real services like Google Meet, Cloudflare, and Twilio — to give you the most comprehensive leak test available.
How to Fix a WebRTC Leak
1
Use a VPN with WebRTC protection
Mullvad, ProtonVPN, and NordVPN block WebRTC leaks at the browser level automatically.
2
Install WebRTC Leak Prevent extension
Available for Chrome and Firefox — forces WebRTC traffic through your VPN tunnel.
3
Disable WebRTC in Firefox
Go to about:config → search media.peerconnection.enabled → set to false.
4
Use Brave Browser
Brave has built-in WebRTC blocking. Go to Settings → Privacy → Block WebRTC IP leakage.
5
Use Tor Browser
Tor Browser completely disables WebRTC — the most secure option.
