Visit Sulu

Sulu is an open-source content management system built on the Symfony PHP framework. It addresses the need to manage multiple websites from a single installation, handle multilingual content, and deliver content through either traditional rendering or headless, API-first approaches. Content and presentation can be kept separate, allowing flexibility in how sites are designed and extended.

Core capabilities include Webspites multisite management, asset management, personalized content delivery, SEO and analytics integration, form management, shareable preview links, and task automation. Sulu supports traditional, headless, and hybrid delivery models, with an API for integrating tools such as HubSpot, Salesforce, and search engines. It is deployment-agnostic, compatible with Kubernetes, and built on Symfony components with a complete test suite. The platform also includes Sulu.ai for AI workflows.

Sulu is aimed at developers, content teams, marketers, and digital agencies. It is available under permissive open-source licenses, with professional support, consulting, training, and development services offered by the core team.
