What is HedgeDoc?
HedgeDoc, formerly known as CodiMD, is an open-source Markdown editor that runs in the browser and is installed on your own server. Anyone given a note's link can edit it with others in real time, and the same Markdown can produce graphs, diagrams and reveal.js slide decks. Revisions track the changes to each note. The code is free under the AGPL 3.0 license, and the project's site lists no hosted or paid edition.
HedgeDoc is free to use. See every plan
Good for
- Teams that write in Markdown and keep notes on their own server
- Building and presenting slide decks from Markdown
- Small servers: the project says it runs on a Raspberry Pi
Worth knowing
- There is no hosted service: you install it on your own server, from the release bundle or the Docker image, and put a reverse proxy in front of it.
- PDF export was removed because of security vulnerabilities; the FAQ suggests the browser's print-to-PDF function in the meantime.
- Only one server process can run against a database, so the FAQ rules out running several instances side by side.
- The public demo comes with a warning about its reliability and is meant for trying the editor, not for keeping notes.
Key features
- Collaborative Markdown editing
- Notes are written in Markdown and edited by several people in real time. Sharing a note's link is all it takes to bring co-workers in.
- Presentation mode
- Slides are written in Markdown and presented straight from the browser, powered by reveal.js.
- Graphs and diagrams
- Notes can include many types of graphs and diagrams as well as embedded content, all written inside the Markdown.
- Permissions and revisions
- Each note's permissions are set from a dropdown, and revisions keep track of changes so a note can be reverted to any older version.
- Sign-in options
- The documentation has setup guides for LDAP, OAuth and SAML, and for signing in with GitHub, GitLab, Keycloak, Mattermost, Nextcloud, Authelia and Microsoft Entra ID.
- Light server requirements
- It needs Node.js 20 or later and a PostgreSQL, MySQL, MariaDB or SQLite database, and the project says it runs smoothly on a Raspberry Pi.
