Overview

Build Websites with Flexibility and Power

Joomla! CMS is a mature, community-driven content management system that empowers developers, agencies, and organizations to build sophisticated websites and web applications. Written in PHP and supporting MySQL, MariaDB, or PostgreSQL databases, Joomla provides a robust foundation for projects ranging from simple blogs to complex enterprise portals.

Developer-Friendly Architecture

The platform offers a modular architecture with extension support, PSR-4 autoloading, and modern development workflows using Composer and npm. Developers can clone the repository, set up a local environment, and contribute to the codebase or build custom extensions. The active community maintains comprehensive documentation for both developers and web designers.

Multilingual and Scalable

Joomla excels at multilingual website management and scales to meet diverse deployment needs. Distributed under the GNU GPL v2+ license, it's backed by Open Source Matters, Inc. and thousands of contributors worldwide. Whether you're building a corporate site, community portal, or e-commerce platform, Joomla provides the tools and flexibility to bring your vision to life.
