Joomla is a free, open-source Content Management System (CMS) built on PHP and MySQL. It ships with built-in user management, multilingual support, access control lists (ACL), content versioning, and workflow — all without requiring third-party plugins. Joomla sits between WordPress and Drupal in complexity: more powerful than WordPress for sites needing fine-grained permissions and complex content hierarchies, but more approachable than Drupal for most organisations.
Joomla sits between WordPress (simpler, more plugins) and Drupal (more complex, more flexible) in terms of power and ease of use. It ships with a comprehensive user management system, multi-language support, access control lists, versioning, workflow, and a rich extension ecosystem — all out of the box without requiring third-party plugins for core functionality.
Joomla is particularly well-suited to sites that need fine-grained user permissions, multilingual content, or complex content hierarchies — use cases where WordPress often requires extensive plugin stacking.
