About
A free toolkit for understanding satellite-internet performance.
SatSpeedCheck is a free, independent Starlink and satellite-internet toolkit. It exists to help users judge whether their connection looks normal for their situation, not just to display a download number.
What SatSpeedCheck does
The site combines a browser-based speed test, typical regional Starlink speed benchmarks, calculators, and practical guides. The goal is to make it easier to compare your own result with estimated regional patterns, then think through likely causes such as plan choice, obstruction risk, location context, or off-grid power constraints.
How the tools work
The speed test runs entirely in your browser and measures download, upload, and latency against Cloudflare's public edge endpoints at speed.cloudflare.com. SatSpeedCheck does not receive or store your speed-test payload data or results on its own servers.
Test results and history are stored locally in your browser's localStorage on your own device. No account or sign-up is required, and clearing your browser data removes that local history.
Benchmark methodology and limits
SatSpeedCheck includes a benchmark dataset of typical Starlink speeds by region. These values are estimates derived from public and community data, and they are framed as typical reference ranges, not live readings from Starlink or from individual users.
Satellite-internet performance can vary by location, time, congestion, hardware setup, obstructions, Wi-Fi conditions, and plan. Use the benchmarks as context, then verify with your own setup and repeat tests where possible.
Who it is for
SatSpeedCheck is built for current satellite-internet users, prospective buyers, RV and overland users, off-grid households, and remote workers who need a clearer read on whether their performance is reasonable for their context.
