What is a WebRTC leak?

WebRTC is a browser feature that can reveal your real IP address even when you are connected through a proxy or VPN. A WebRTC leak happens when a website obtains an IP that differs from your proxy exit IP, exposing your true location.

How do I know if my proxy is leaking my identity?

This test compares your browser timezone, language, and WebRTC-derived IP against the IP address websites actually see. Mismatches reveal that your proxy setup is inconsistent and easy to detect.

What is a browser fingerprint?

A browser fingerprint is a combination of signals — canvas rendering, WebGL, audio, fonts, screen size, and hardware — that together identify your browser even without cookies. The more unique it is, the easier you are to track across sites.

What This Test Checks

WebRTC IP leak — whether your browser reveals an IP different from your proxy exit IP, exposing your real connection
Timezone mismatch — if your browser timezone doesn't match the country of your IP, sites flag you as a proxy user
Language mismatch — if your browser language doesn't fit your IP's country
Proxy / datacenter flag — whether your current IP is already classified as a proxy or hosting IP
Fingerprint — canvas, WebGL, audio, fonts, screen, and hardware signals that identify your browser without cookies

Why Leaks Defeat Your Proxy

A proxy changes the IP a website sees, but it does nothing about WebRTC, your timezone, or your fingerprint. If your IP says New York but your browser timezone says Shanghai, anti-fraud systems instantly know something is off — and link your accounts anyway. Consistency is everything: your IP, timezone, language, and fingerprint must tell one coherent story.

Residential proxies give you real ISP IPs in the region you're targeting. Pair them with a browser profile whose timezone and locale match, and the mismatches this test finds disappear.
