The Phoronix Test Suite is available under the GNU GPLv3 free software license. The Phoronix Test Suite can be used for any personal or professional usage free of charge. Patches to the Phoronix Test Suite are welcome via GitHub.
The only mandatory requirement for the Phoronix Test Suite on Linux, Solaris, *BSD, Hurd, and macOS operating systems is PHP CLI (packages for it are generally called php7-cli or php-cli or just php). Only PHP is needed and not a web server or other packages commonly associated with PHP.
Many of the benchmarking profiles do require the standard development tools/libraries (GCC compiler, etc) and other common programs. However, on many Linux distributions and operating systems the Phoronix Test Suite is able to use the software's package management system for installing these additional dependencies.
Below are the official release packages for the current stable release of the Phoronix Test Suite. The Phoronix Test Suite as a Docker image is also available on Docker Hub as phoronix/pts for a Linux-based container image with a number of the most popular tests pre-seeded to make for a convenient download.
Phoronix Test Suite 11.0 is under development as the next feature release.
The open-source Phoronix Test Suite and Phoromatic benchmarking software is developed on GitHub where you can track the latest development code.
