Summary

LibreSpeed is a lightweight JavaScript speed test that measures download, upload, ping, and jitter using XMLHttpRequest and Web Workers. It supports IE11, current Edge, Chrome, Firefox, Safari, and mobile browser versions. Telemetry and result sharing are optional, and installations can select among multiple test points by choosing the one with the lowest ping. A separate stability test reports current, average, minimum, and maximum latency, jitter, failed-request percentage, threshold alerts, and CSV export. It can test against a local backend, configured test points, or Google, Cloudflare, and Apple. Installation uses a web server such as Apache, nginx, or IIS with PHP 5.4 or newer, though other backends are available. Optional result storage works with MariaDB, MySQL, Microsoft SQL Server, PostgreSQL, and SQLite. The project also provides an Android client template, a command-line client, and a .NET client library through NuGet. Go and Rust implementations are available; the Node.js implementation is partial and not recommended. LibreSpeed is free and open source, with self-hosting and no paid plans listed.

Who it is for

LibreSpeed suits people who want to run a speed test on their own web server or use its client options. Its stability test and optional result storage may suit users who need more than basic speed measurements.
