About Sulu

Sulu is an open-source PHP content management system built on the Symfony framework. It is meant for robust multilingual and multi-portal websites, and it provides an administration interface for managing the whole content lifecycle that can be extended by developers.

This repository holds the core framework that implements the CMS functionality and is a dependency of every Sulu project. To start a new site, developers use the sulu/skeleton project template, and the Sulu organization on GitHub lists official bundles for extending existing projects. Documentation covers installation and usage, and community help is offered through Slack and GitHub Discussions.

The project is community-driven and backed by partner companies, with a transparent development process. It is written in PHP, licensed under MIT and runs on your own hosting. It suits PHP and Symfony agencies and teams building custom content-heavy sites that need flexibility beyond what an off-the-shelf blogging CMS gives.
