Browser-based diagnostic tools for IP analysis, WebRTC leak testing, DNS inspection, HTTP header analysis, and TLS verification. No tracking, no persistent storage. Some tools use server-side request reflection — nothing is retained.
Each tool runs entirely in your browser using public, CORS-enabled APIs. No account required, no data stored.
Full geolocation, ASN, ISP, timezone, and Cloudflare PoP for your current connection.
Run tool →Detect whether your browser leaks your real IP address via WebRTC ICE candidates.
Run tool →Inspect every header your browser sends to remote servers, including proxy headers and user-agent.
Run tool →Identify your DNS resolver via Cloudflare DoH and Google DoH. Detect ISP vs encrypted DNS.
Run tool →Measure round-trip time to Cloudflare, Google, Fastly, Akamai, and AWS edge nodes.
Run tool →Detect your TLS version, key exchange algorithm, HTTP protocol, and HTTPS scheme.
Run tool →Run a full battery of privacy tests: WebRTC leak detection, DNS resolver fingerprinting, proxy header analysis, and browser fingerprint scoring. Get an overall privacy score in seconds.
Open Privacy CheckSimple REST endpoints for IP info, timestamps, and request headers. No API key required. Rate-limited at 60 req/min per IP. Perfect for scripts, dashboards, and monitoring tools.
Tools run client-side in your browser. We use only public, CORS-enabled endpoints to retrieve information about your connection — none of it passes through our servers.
Runs the JavaScript. No extensions needed, no install, no account.
Cloudflare (1.1.1.1), Google DoH — all CORS-enabled.
