Diagnostics

Security & speed tools

See the IP your connection exposes, check for WebRTC leaks, and measure ping, download, and upload — heavy work stays in your browser.

IP & geolocation

We read your public IP on our server, then look up country, city, and ISP in the browser.

Idle
Checking your IP…

WebRTC leak test

Collects local and public addresses visible to WebRTC and compares them with the server IP.

Idle
Scanning WebRTC candidates…

DNS leak test

Asks your device to resolve one-time hostnames. The resolvers that show up should be your VPN or a DNS you chose — not your ISP, if you expect the tunnel to hide lookups.

Idle
Probing DNS resolvers…

Resolver log via bash.ws

IP, WebRTC, and DNS checks run automatically. Start the speed test manually so it does not slow the page.
