LibreSpeed is a self-hosted speed test tool implemented in JavaScript that measures download, upload, ping, and jitter without requiring Flash, Java, or WebSocket technology.
The tool solves the problem of running internet speed tests on your own infrastructure rather than relying on third-party services. It uses XMLHttpRequest and Web Workers to perform measurements in the browser, keeping the implementation lightweight. The backend can run on Apache, nginx, or IIS with PHP 5.4 or newer, and optionally stores results in MariaDB, MySQL, PostgreSQL, Microsoft SQL Server, or SQLite. The frontend loads from a modern UI by default but supports a classic interface as well, with a design switcher that respects configuration and URL parameters.
LibreSpeed suits organizations wanting to host speed testing internally, whether for network diagnostics, ISP validation, or user-facing speed measurement. The installation process is straightforward for anyone with a web server and PHP already running. The tool includes optional features like telemetry, results sharing, multiple test points, and a connection stability test with latency charting and CSV export. Mobile browsers are fully supported. The project provides ecosystem clients including an Android app template, a command-line client, and a .NET library.
The project maintains active development with regular code quality practices including npm-based development tasks, linting, and formatting standards documented for contributors. The codebase supports multiple backend implementations beyond PHP, indicating ongoing architectural flexibility. Documentation includes installation videos and detailed guides for specific deployment scenarios like Debian systems.
