Fast, Open Network & Internet Diagnostics
Measure your broadband throughput, inspect round-trip latency, analyze jitter, and diagnose connectivity issues with real browser-driven diagnostic benchmarks.
Internet Speed Test
Run a real multi-stream throughput benchmark directly from your browser. Measures active download rate, upload speed, round-trip latency (ping), and jitter using statistical trimmed-mean calculations.
Diagnostic Suite Tools
Every tool is engineered for speed, privacy, and zero account friction.
Internet Speed Test
Benchmark download speed, upload speed, ping, and jitter with real multi-stream data transfers.
Ping Test
Measure real network latency, minimum, average, maximum RTT, jitter, and packet loss with 20 live probes.
DNS Resolution Benchmarker
Compare response time across public recursive DNS resolvers (Cloudflare, Google, OpenDNS).
HTTP & Security Header Inspector
Audit CORS headers, HSTS, CSP, and TLS ciphers for any target web URL.
Platform Engineering Principles
Why this diagnostic platform is built differently from generic tools websites.
Real Client Diagnostics
No fake progress bars or predetermined estimates. Diagnostic tests execute genuine network streaming operations via modern browser APIs.
Privacy & Zero Accounts
No logins, no cookies for tracking, and test results are not stored in an application database. Network streams are consumed in-memory and discarded.
Transparent Accuracy
We openly document test methodology, statistical filtering, and browser limitations. We never present browser metadata hints as measured speed.
