How we measure

Median time to a usable sandbox in Coldtally's latest daily run. Not yet measured: Vercel Sandbox. Help us measure Vercel Sandbox. Blaxel: pricing only. Cloudflare Sandbox (grey) is timed inside its benchmark Worker, which leaves out network latency, so it isn't counted as fastest. Startup time is a secondary check; prices are the main comparison.
