WebRTC Leak Test

WebRTC Leak Test

The test runs entirely in your browser: it collects the local and public IP addresses exposed through WebRTC/ICE.

What Is a WebRTC Leak?

WebRTC (Web Real-Time Communication) is the standard that lets browsers make voice and video calls without a plugin. Here is the catch: to connect two browsers directly, WebRTC needs your device's learns real IP addresses from STUN servers and those addresses can be read with JavaScript. Even if your proxy is working perfectly, a malicious page can grab your real IP over WebRTC with a single line of code.

This is a channel entirely separate from HTTP traffic — which is why using a proxy or a VPN does not stop a WebRTC leak on its own.

How to Read the Test Result

• The test shows only your proxy IP is what shows up: no leak, your configuration is safe.
• Next to the proxy IP your real public IP also shows up: there is an active leak; follow the steps below.
• If only a local network address (192.168.x.x) shows up: the risk from the outside world is low.

How to Stop a WebRTC Leak

Firefox

In the address bar, type about:config type it in, media.peerconnection.enabled key to false Set it like this and WebRTC is disabled completely.

Chrome

WebRTC cannot be fully disabled in Chrome; with an official extension such as "WebRTC Network Limiter" you can force traffic through the proxy interface only.

Anti-Detect Browsers

Anti-detect browsers used for multi-account work offer a per-profile option to replace the WebRTC value with the proxy IP — in social media operations this is the recommended method.

Full Privacy Check

WebRTC is not the only leak channel. IP verification and DNS test to complete the triple check; if all three results are clean, your proxy identity is consistent.
