Contao

Contao is a Symfony-based PHP CMS that has been in active development since 2006. It is most widely used across German-speaking Europe for institutional websites, corporate intranets, and association portals — contexts where editorial control, structured content, and strict user permissions matter more than ease-of-use for casual editors.

The permission system is one of Contao’s most distinctive features. User groups can be given access to specific page branches, individual modules, content elements, and backend sections. A regional editor can be confined to their section of the site tree without any visibility into other areas. This level of granularity is overkill for small sites but exactly what regulated organisations need when managing content across multiple editorial teams.

Several common site features are built into the core rather than relying on third-party extensions. The newsletter module handles subscriber lists, campaigns, and unsubscribes. The events module manages a calendar with recurring events. Form generation, file management, and search indexing are all included. For organisations that want a coherent, maintained feature set rather than assembling plugins from different authors, this is an advantage.

Contao is built on Symfony, which gives developers a familiar, modern PHP foundation for extensions and customisation. The framework abstracts away much of the CMS internals cleanly.

Outside German-speaking Europe, the community is smaller and English-language resources are thinner than WordPress or Drupal equivalents. With 426 GitHub stars, the project is maintained but niche. Teams without German-language community access may find troubleshooting slower.
