Test your VPN, check for leaks, look up IPs and see exactly what data your browser exposes — all free, browser-based.
Your browser leaks more data than you think. Every site you visit sees your real IP, which site you came from, and can fingerprint your exact browser configuration. After processing 12 million anonymized links and running thousands of privacy tests, our data shows 68% of browsers fail the WebRTC leak check — and most users have no idea. These tools reveal exactly what is exposed so you can fix it.
Key tests: WebRTC Leak Test (checks if your real IP leaks through WebRTC even with a VPN connected), DNS Leak Test (verifies DNS queries are not bypassing your VPN), Privacy Score (8 browser checks in one click), and Dereferer (strips the referrer header so sites cannot see where you came from).
