LibreSpeed is a self-hosted HTML5 speed test that lets you measure your internet connection's download speed, upload speed, ping, and jitter. It supports multiple backends including PHP and Node.js, making it compatible with virtually any hosting environment.

Easy to set up and highly configurable, LibreSpeed works across all modern browsers and is mobile-friendly out of the box. It can be configured with multiple test servers, allowing for distributed testing across different geographic locations. The project has been actively maintained since 2016 and has a strong community of contributors.

LibreSpeed is ideal for ISPs, hosting providers, and organizations that want to offer their own speed test service without sending users to third-party sites. Its privacy-respecting design means all test data stays on your own servers, and the LGPL-3.0 license ensures the project remains free and open.
