## What it is
LibreSpeed is a self-hosted, lightweight HTML5 internet speed test application built with JavaScript, XMLHttpRequest, and Web Workers. It measures download, upload, ping, and jitter, with optional telemetry, result sharing, and multiple test servers, supporting PHP, Node.js, and other backends.

## Use cases
- self-host a speed test server instead of using Ookla Speedtest
- measure download and upload bandwidth of my connection
- check ping and jitter to my own server
- run a privacy-friendly speed test without third-party tracking
- deploy a speed test on my LAN to diagnose network issues
- collect speed test results with telemetry and share them
- test connection stability with latency charts and packet loss tracking

## When to choose
- you want a self-hosted, privacy-respecting alternative to Speedtest.net
- you need a lightweight HTML5 speed test with no Flash, Java, or WebSockets
- you want optional telemetry with results stored in your own database
- you need a mobile-friendly speed test that works in all modern browsers
