Speed Test

A small same-origin speed test for Cloudflare Pages.

The page measures download speed, upload speed, idle latency, jitter, and loaded latency against the domain it is served from. There is no domain-specific config in the app, so the same build can be deployed to multiple hostnames. Transfer payloads are generated test bytes.

Run locally
