HedgeDoc (formerly known as CodiMD) is an open-source, web-based, self-hosted, collaborative markdown editor.
You can use it to easily collaborate on notes, graphs and even presentations in real-time. All you need to do is to share your note-link to your co-workers and they’re ready to go.
You don’t need extra software. The editor runs in your browser.
Stay in control of your data. Keep it on your server.
Collaborate in real-time with friends, family and colleagues.
Use HedgeDoc to build and present slides in markdown. Powered by reveal.js!
HedgeDoc supports many types of graphs, diagrams and embedded content.
Manage permissions of your notes with a simple dropdown selection.
Revisions keep track of changes to your notes and even let you revert to any older version.
HedgeDoc doesn’t need much resources. It even runs smooth on a Raspberry Pi!

Yes, this project was formerly known as CodiMD, but in 2020 we decided to rename our project to HedgeDoc to avoid confusion with another project of the same name.
The HedgeDoc source code is available on GitHub and licensed under AGPL 3.0. Everything is open source and free as in free speech. Read it, understand it, help us to improve it!
