How it works: The browser downloads (or uploads) a generated test file from this server; JavaScript measures total bytes / elapsed time and reports bits/sec converted to kbps & Mbps. Results depend on the user's network, browser, and the hosting server.

Made for quick testing — add HTTPS and server-side rate limiting for production.
