Build a Real Speedtest in Vanilla JS with Cloudflare API
A developer created a lightweight internet speed test using only HTML, CSS, and ~250 lines of JavaScript, leveraging Cloudflare's public API. The tool measures ping, download, and upload speeds without any dependencies or tracking scripts. It delivers accurate results in under 50 KB and runs on any device.
Meridian48 take
