Joomla!

Joomla! is a free, open‑source content management system that lets users create and maintain websites and online applications. It runs on a web server with PHP and a compatible database such as MySQL, MariaDB, or PostgreSQL, and provides a mobile‑ready, multilingual platform with extensible extensions and templates. The core includes multi‑user permission levels, SEO‑friendly features, and a flexible architecture that supports custom development.

The software is aimed at web creators, designers, and developers who need a stable, self‑hosted CMS that can be extended through a large ecosystem of free extensions and themes. It is suitable for personal sites, corporate portals, and complex web applications, offering a balance between ease of use and deep configurability.

Joomla! is distributed under the GPL‑2.0 license, with a stable release history and active community support. The source repository includes build pipelines for PHP 8.1, Node 20, and npm 10, and developers can set up a local environment using Composer, npm, and Git following the provided documentation.
