See what the internet
already knows about you.
Real network and privacy diagnostics — leak tests, IP exposure, DNS, and more. No account, no upload. Just the data your connection is actually broadcasting right now.
Eight checks. One picture of your exposure.
Each test targets a specific way your identity or connection can leak. Run one, or run them all — every result comes with a plain explanation of what it means.
WebRTC Leak Test
Reveals the real IP address WebRTC can expose straight past your VPN.
Run test →DNS Leak Test
Checks whether your DNS queries slip outside the encrypted tunnel.
Run test →IPv6 Leak Test
Detects IPv6 traffic slipping past an IPv4-only VPN configuration.
Run test →What's My IP
Your public address, geolocation, and the network operator behind it.
Run test →Open Port Scanner
Scans your own connection for ports left exposed to the internet.
Run test →Latency & Packet Loss
Measures round-trip time and how stable your connection really is.
Run test →Breach Check
See whether your email appears in known, publicly disclosed data breaches.
Run test →Browser Fingerprint
How uniquely identifiable your browser is to trackers, without cookies.
Run test →Built by network engineers.
Here's how the tests work and what we do — and don't — do with the results.
01 Runs where you are
Client-side tests execute in your browser against your own connection. WebRTC and fingerprint checks never touch a server we control.
02 Open about method
Every test page states exactly what it measures, how it measures it, and what a red or green result does and doesn't prove. No black boxes.
03 Nothing to store
No account, no history. We don't retain your IP or results. Close the tab and there's nothing left behind on our end.
pc = new RTCPeerConnection(iceServers)
pc.createDataChannel("")
pc.onicecandidate = (e) => {
parse(e.candidate) → { ip, typ }
// typ 'srflx' = your real public IP
// leaking past the tunnel
}
// result you'd see:
status: no reflexive candidate exposed ✓
