Is WebRTC leaking your IP?

WebRTC can reveal IP addresses your browser wouldn't otherwise share - including your real one behind a VPN. This test gathers the candidates your browser exposes and shows exactly what leaks.

Running the test…
01

Why WebRTC leaks happen

WebRTC needs your IP addresses to connect peers directly for calls and file transfers. To do that it can gather your local network IPs and, via STUN servers, your public IP - bypassing a proxy that only covers normal web traffic.

02

How to prevent it

You can disable WebRTC, but that breaks video calls. The better fix is making WebRTC use the same proxy as everything else, per profile - how Donut Browser handles it so calls still work without leaking.

Every profile its own identity

Donut Browser is a free, open-source anti-detect browser. Each profile gets its own consistent fingerprint, IP and proxy, so the signals on these tools can't tie your accounts together or back to you.

Questions, answered.

It's when the WebRTC feature in your browser exposes IP addresses - your local network address or your real public IP - that reveal who and where you are, even behind a VPN or proxy.
