LightTest is the ultra-lightweight command-line network speedtest utility built for low-spec devices, servers, and power users who demand accurate results without all the bloat.
Forget those heavy, flashy, resource-hogging speed test apps. LightTest runs from your terminal — even on on old Raspberry Pi, a rented VPS, or a Termux session on a budget Android phone. It measures your real download speed, upload speed, and ping (latency) in seconds.
Sometimes you simply need to know: "Is my internet fast right now?" — without launching a monster app, waiting for ads, or dealing with a web-based test that hogs memory. LightTest gives you clean, precise numbers instantly. That’s it. That’s the magic.
Runs with incredibly low memory and CPU usage. Perfect for old hardware, headless servers, and IoT devices.
Get your download, upload, and ping metrics in under 15 seconds. No waiting, no fuss.
Uses the Rich library to display colorful, well-formatted output directly in your terminal.
Written in clear Python, fully transparent. No hidden analytics, no ads, no tracking — just pure functionality.
From Termux on your phone to Ubuntu on your server. If you have a terminal, LightTest runs.
Only needs Python and the Rich library. Nothing else required. No crazy installations.
Follow these simple steps to run LightTest on your Windows machine right now. No programming skills needed!
