Textpattern

A PHP‑based content management system that runs on a standard web server with MySQL. It provides a browser‑driven administrative interface, supports more than fifty languages, and includes built‑in handling for Textile markup with optional Markdown via a plugin. The core is deliberately lightweight, avoiding extra script libraries, while offering a tag‑based template language that lets developers shape HTML directly.

The system is self‑hostable, free to use, and distributed under the GPL‑2.0 license, with no subscription or tiered pricing. Its architecture is designed for extensibility; a large collection of community‑maintained plugins can add functionality without altering the core. The interface emphasizes simplicity and accessibility, aiming to keep administrative panels uncluttered.

Target users are individuals or organizations that need a stable, open‑source CMS for building and managing websites, especially those who prefer direct control over markup and templating. The project has over two decades of development, an active support forum, and a community that contributes code, translations, and extensions.
