Diagnostics

Network Tools

Six real-time diagnostic tools powered by public APIs. No tracking, no persistent storage. Some tests use lightweight server-side reflection of your own request data.

IP Analysis
Initializing…

Full geolocation and network info for your current IP using Cloudflare trace. Shows IP, country, TLS version, HTTP protocol, and datacenter.

WebRTC Leak Test
Ready

Creates an RTCPeerConnection using public STUN servers (Cloudflare + Google) and parses ICE candidates for any leaked public IPs. mDNS concealment is also detected.

A VPN or proxy does not automatically prevent WebRTC leaks. This tool tests whether your browser leaks your real IP regardless of your connection.

Click "Run" to start WebRTC leak test…
HTTP Inspector
Ready

Fetches the headers your browser sends to this server. Detects proxy headers, forwarding headers, user-agent, and accept-language.

headers-inspect
Click "Run" to inspect HTTP headers…
DNS Probe
Ready

Attempts to infer DNS resolver behavior using Cloudflare DoH and Google DoH. Results may reflect the DoH provider rather than your actual system resolver.

dns-probe
Click "Run" to probe DNS resolver…
Latency Test
Ready

Measures RTT to 5 CDN edge nodes using performance.now(). Results include a visual bar for quick comparison.

latency-test
Click "Run" to measure latency…
TLS & Connection
Ready

Retrieves TLS version, HTTP protocol, key exchange algorithm, and connection scheme via Cloudflare's trace endpoint.
