Joomla is a veteran open-source CMS that holds the second-largest market share among self-hosted CMS platforms after WordPress — powering millions of sites for small businesses, government agencies, and non-profits worldwide. Its flexible user access management (ACL) and multilingual support built into the core (no plugin required) make it popular for organizations with complex permission structures and international audiences. Joomla's extension directory has 8,000+ extensions for adding functionality. Joomla sites are identifiable through /media/jui/ paths for jQuery UI assets, com_content references in URL query strings (index.php?option=com_content), the Joomla generator meta tag containing the version number, and /administrator/ path for the backend. The Joomla JavaScript namespace and component-specific CSS classes (mod-articles-category, com_content) appear throughout the markup. Joomla is free and open-source.
