Assuming you have PHP and a web server installed, the installation steps are quite simple.

  1. Download the source code and extract it
  2. Copy the following files to your web server's shared folder (ie. /var/www/html/speedtest for Apache): index.html, speedtest.js, speedtest_worker.js, favicon.ico and the backend folder
  3. Optionally, copy the results folder too, and set up the database using the config file in it.
  4. Be sure your permissions allow execute (755).
  5. Visit YOURSITE/speedtest/index.html and voila!

Installation Video

This video shows the installation process of a standalone LibreSpeed server: Quick start installation guide for Debian 12

Android app

A template to build an Android client for your LibreSpeed installation is available here.

CLI client

A command line client is available here.

.NET client

A .NET client library is available in the LibreSpeed.NET repo (NuGet), maintained by MemphiZ.

Development

If you want to contribute or develop with LibreSpeed, see DEVELOPMENT.md for information about using npm for development tasks, linting, and formatting.

Docker

A docker image is available on GitHub, check our docker documentation for more info about it. The image is built every week to include an updated version of the ipinfo-DB used for ISP detection. Also this ensures, that the latest security patches in PHP are installed. Therefore we recommend to use the latest image.
