WebRTC leak test
Video calls in your browser use WebRTC. See which address it can show a site.
Testing…
WebRTC in your browser
Our test server tells your browser the address it sees, keeps nothing and writes no log.
What WebRTC can show a site
Any page can ask your browser for it, with no call, no camera and no click.
Your real address
If WebRTC goes around your VPN, a site learns the address your provider gave you.
Your home network
Some browsers also show your device's address on your home or office network.
A way to know you
An address that stays the same helps sites link your visits, even after you clear cookies.
Keep WebRTC inside KazaVPN
Connect with the KazaVPN app and WebRTC shows sites our server's address, the same one they see when you browse.

Questions about WebRTC leaks
What is a WebRTC leak?
WebRTC lets your browser make calls and share files straight with another device, and to do that it asks for your address. A leak is when it shows a site an address outside your VPN.
How do I stop a WebRTC leak?
Connect with the KazaVPN app on this device and run the test again, so your browser's calls go through KazaVPN along with everything else.
Do you keep what the test finds?
No. Our test server tells your browser the address it sees and keeps nothing, and this page stores nothing on your device.
