What framework does Joomla use?

Joomla is a PHP-based open-source CMS that uses its own custom MVC framework, often referred to as the Joomla Framework. It’s modular and adheres to PHP object-oriented programming best practices. The framework follows the Model-View-Controller (MVC) design pattern, separating data handling (model), UI rendering (view), and logic control (controller).

This architecture allows developers to create robust extensions, modules, and templates with clean separation of concerns. Joomla also integrates Symfony components under the hood, offering some cross-compatibility with more modern PHP frameworks.

If you're working on a CMS-heavy application with complex user permissions or multilingual support, Joomla’s framework can be highly effective. Hire Joomla developers from FatCat Remote to build scalable, content-rich websites with flexible admin tools.
