All checks at a glance. Cheap probes run automatically; the throughput test waits for your click — it downloads ~20 MB.

Sees what IP addresses your browser would expose to a peer via WebRTC, even with a VPN active.
Computes JA3 from your browser's TLS ClientHello — the exact fingerprint a DPI sees.
This test is not switched on here yet — open the neighbouring one, it works. Browser Fingerprint
Checks which DNS resolvers actually answer for you — even when a VPN is active.
This test is not switched on here yet — open the neighbouring one, it works. WebRTC Leak Test
Streams 10 MB over two paths and compares throughput. A gap is worth a look but proves little on its own: Cloudflare is hundreds of edges near you, our endpoint is a single server, and it is almost always the slower of the two.
Test downloads ~20 MB total (10 MB per path). Skip if you are on metered mobile data.
Each opens as its own page with the full readout and an explanation of what the result means.
What our server sees about you: IP, geolocation, every HTTP header your client sent. The exact picture any site receives.
Which resolvers your device actually uses, who controls them, and whether your queries stay inside your VPN tunnel.
Does the remote side see your real IP through WebRTC while a VPN is on. Standard but essential check.
See your client through the eyes of DPI. Live JA3 and JA4 hashes, compared against common browsers.
How unique is your browser? Canvas, WebGL, audio, and platform parameters that trackers combine into a stable identifier.
Check connectivity to popular services (YouTube, Discord, Telegram, and more) across multiple protocol layers.
Parallel speed measurements to popular services and control endpoints. See exactly who your ISP is throttling.
Does QUIC (HTTP/3) actually reach the major CDNs from your network? Detects whether your browser falls back to HTTP/2.
These checks describe what is visible about you from outside, and what is getting in the way of your connection. Logrus changes exactly that: it picks a transport that gets through your filter and hides the content and destination from your ISP. It does not change your browser fingerprint — the browser does that.
If it is not for you, do nothing: the access simply expires.
