Full CMS

Grav (15.7k ★s) is a flat-file CMS that stores content as plain Markdown files instead of a database, edited through a browser-based Admin panel, and runs on any standard web host with PHP 8.3+. These four skeletons – fully open-source, built on the newly released Grav 2 – cover course hubs, multi-course sites, and open publishing spaces, well suited to OER and other open educational content.

Each shares the same portable Markdown files and optional Git Sync – Course Hub, MultiCourse Hub, and Publishing Space also support LMS-ready embedding for platforms like Canvas and Moodle.

Also Free: Git Page Link Plugin

The Git Page Link Plugin works with most Grav themes – not just these four skeletons. It adds an "Edit this Page" link back to the Markdown source, for open authoring and community contribution.
