TYPO3

TYPO3 is a powerful enterprise content management system that handles everything from small business sites to massive multi-site deployments for global organizations. It gives you full control over content editing, user permissions, and site structure without locking you into a rigid platform. The system runs on PHP and supports MySQL, MariaDB, PostgreSQL, and other database backends.

TYPO3 ships with a flexible templating engine called Fluid, a rich text editor (CKEditor5), and a drag-and-drop page builder. It supports multisite management, granular access controls, workspaces for staging content, and a built-in form builder. You can extend it through thousands of extensions available in the TER (TYPO3 Extension Repository). The backend interface is fully responsive and supports multiple languages out of the box.

This is a great fit for agencies, universities, government bodies, and large enterprises that need a reliable CMS with strong security and compliance features. TYPO3 is maintained by the TYPO3 Association and licensed under GPL-2.0. Major adopters include Lufthansa, Volkswagen, and the European Commission.
