What it is

MODX Revolution is an open-source content management system and application framework written in PHP. It lives in the MODX open-source PHP CMS ecosystem and is distributed under the GNU General Public License version 2 or later. The project provides a downloadable PHP application that can be installed on a server, configured through MODX documentation, and extended through its modular core.

The concrete problem it addresses is the need to manage website content while retaining control over presentation and application behavior. MODX is positioned for projects that go beyond a simple blog, including multi-language and multi-domain corporate sites, personal blogs, and mobile APIs. It aims to let users control markup and design without requiring custom code for those tasks, while still allowing developers to tailor the core for custom requirements and different traffic levels.

Key capabilities

• Provides a content management system and application framework for PHP-based websites.
• Supports multi-language and multi-domain corporate sites, personal blogs, and mobile APIs.
• Lets users control markup and design without requiring custom code for presentation work.
• Uses a modular and extensible core that can be tailored for custom requirements and varying traffic levels.
• Maintains a changelog for the 3.x branch and links to server requirements, installation, upgrade, and documentation pages.
• Accepts community contributions through GitHub issues, feature requests, code contributions, and Crowdin translation work.
• Publishes security guidance through a SECURITY file and community support through MODX forums.

Who uses it and how

• Companies use MODX Revolution to run corporate websites that need multiple languages, multiple domains, and custom content structures.
• Site builders and editors use it to publish blogs and content-driven sites while controlling markup and design without writing custom code for each change.
• Developers use it as an application framework to build mobile APIs and custom PHP applications on top of the MODX core.
• Community members use GitHub to report issues, request features, contribute code, and help translate lexicons through Crowdin.
• Existing MODX 2.x users use documented upgrade paths to move to 3.x, and new users can install from a download or from git.

Getting started

The README points users to download MODX Revolution from modx.com, review server requirements, follow the installation guide, or install via git. It also links to upgrade instructions from 2.x to 3.0 and to the MODX documentation.

When to use it — and when not to

Use MODX Revolution when a team needs a self-hosted, GPL-licensed PHP content management framework for custom content sites, multi-domain projects, or API-backed applications. Do not choose it if the team needs a hosted service with no server administration, because the README describes download, git installation, and server requirements rather than a hosted option. The project is long-lived, but the repository metadata shows 687 open issues and no listed contributor count, so teams should evaluate maintenance and upgrade effort before adopting it.
