Pi Engine is a role oriented application development engine for web and mobile, designed as the next generation and a successor to Xoops. Pi is developed upon PHP and MySQL with selected third-party frameworks including but not limited to Zend Framework 2, jQuery, Bootstrap and Backbone.

Pi Project follows the philosophy of open standard, open design, open development and open management. Pi is born as a complete open source project and intended to build a sustainable ecosystem that benefits all contributors and users.

Pi Engine is started by Taiwen Jiang (Xoops Project Lead and Dev Lead), Marc Desrousseaux (Xoops QA Lead), Hossein Azizabadi (Xoops Persian Lead), Kris (Xoops Council Member and Xoops France Lead), etc. Pi Team is highly inspired by the Xoops led by onokazu (Ono Kazumi), skalpa and phppp (Taiwen Jiang, or D.J.) successively since 2001 and will continue to support and promote Xoops.
