CodiMD
A self-hosted, real-time collaborative markdown editor for creating and sharing notes together.
What is CodiMD?
HedgeDoc is an open-source, real-time collaborative markdown editor that allows multiple users to create and edit notes simultaneously. It solves the problem of asynchronous document collaboration by providing live editing features similar to Google Docs but focused on markdown content. The platform is designed for teams who need to brainstorm, document, and share ideas together in a simple, text-focused environment.
Development teams, open-source communities, educational groups, and any organization needing real-time collaborative documentation tools. Particularly suitable for technical teams who prefer markdown formatting and want self-hosted control over their data.
Developers choose HedgeDoc because it offers real-time collaboration with the simplicity of markdown in a self-hosted package, giving them complete data control. Unlike proprietary alternatives, it's open-source, community-driven, and doesn't lock users into specific cloud services while providing familiar collaborative editing experiences.

- Open source communities needing shared note-taking platforms
- Educational environments for collaborative writing exercises

- Users who prioritize automatic updates and dedicated support over community-driven development
Pros & Cons
Pros
Enables multiple users to edit markdown notes simultaneously with live updates, fostering team brainstorming and documentation sessions as demonstrated in the demo instance.
Provides full data privacy and deployment flexibility by allowing installation on your own servers, avoiding vendor lock-in as highlighted in the setup guide.
Version 2 rewrite splits the codebase into backend and frontend components for improved maintainability and future development, as noted in the state of the project.
Features an engaged community through Matrix chat, forums, and POEditor translations, ensuring ongoing contributions and multilingual availability.
Cons
The README admits HedgeDoc 2 is incomplete with missing features, and v1.x is in maintenance-only mode, creating risk for new adopters seeking long-term stability.
Requires manual setup and server maintenance, which can be a barrier compared to plug-and-play cloud alternatives, as indicated by the install guide.
Lacks extensive integrations or plugins that proprietary tools offer, potentially limiting workflow automation and third-party tool connectivity.
