HedgeDoc (formerly CodiMD) is an open-source, web-based Markdown editor focused on real-time collaboration. It enables teams to co-edit notes in the browser, share note links, and work together on text, diagrams, and presentations.
Key Features
- Real-time collaborative editing in the browser
- Markdown-based notes with support for diagrams and embedded content
- Presentation mode for Markdown slides
- Simple note permission controls for sharing and editing
- Revision history with the ability to review and revert changes
- Designed to run with low system requirements
Use Cases
- Team meeting notes and collaborative documentation
- Workshops, classes, and live note-taking sessions
- Creating Markdown slide decks for internal presentations
Limitations and Considerations
- HedgeDoc 2 is a rewrite and the development branch may not include all features compared to the stable 1.x releases
HedgeDoc is well-suited for groups that want a fast, link-shareable collaborative editor with Markdown-centric workflows. It combines realtime editing with practical publishing features like revisions and presentation mode for everyday knowledge sharing.
