Sulu
Open-source digital experience platform and content management system built on Symfony.
Sulu is a content management system and digital experience platform built on Symfony and written in PHP. Content is kept in a database, and pages render on the server with Twig. The same content is also served through REST and JSON:API, so one installation can run traditional rendering, headless delivery or both. Multiple sites and languages are supported.
A project is created with composer create-project sulu/skeleton and runs behind a web server such as Nginx or Apache. The deployment guide walks through a first deployment with Git and SSH.
Worth knowing
Sulu GmbH, which publishes the software, also offers Sulu.cloud, a hosted version on SymfonyCloud, and names a separate product, Sulu.ai, on the project homepage.
