SatSpeedCheck

About

SatSpeedCheck is a free, independent toolkit for Starlink and other satellite-internet users. The browser-based speed test measures download, upload and latency against Cloudflare's public edge endpoints, needs no signup and keeps test history locally in your browser. Around it sit a 5-year Starlink cost calculator, an off-grid power sizer, a plan picker, a comparison of Starlink with fiber, cable and 5G, an in-browser sky-photo obstruction checker, a result analyzer, country-level coverage context and practical guides.
