Genuinely fast
Speed tests measured against Cloudflare's anycast edge. Every page renders before you can blink.
Truly private
Tools run in your browser. No analytics, no tracking, no data leaves your device unless you ask it to.
Designed with care
Mobile-first, dark/light theme, large tap targets, considered typography. Built like a product, not a tool dump.
Modern stack
React 19, TanStack Start, Tailwind v4. SSR'd HTML for SEO. Zero unnecessary client JS.
How accuracy works
Speed tests use Cloudflare's public speed endpoints with parallel download streams and chunked uploads to saturate your connection. Latency is measured with timing-pruned samples to remove warmup outliers. Network info comes from the Network Information API where available, falling back gracefully when it isn't.
