HedgeDoc
Collaborate on Markdown notes, diagrams, and presentations with HedgeDoc, a web editor that can be self-hosted.
About HedgeDoc
HedgeDoc is a web-based, self-hosted collaborative Markdown editor. Users can share a note link so that others can work on the same notes, graphs, and presentations in real time. The editor runs in the browser, so no separate software is needed. The homepage describes HedgeDoc as formerly known as CodiMD, renamed in 2020 to avoid confusion with another project of the same name.
HedgeDoc is installed on a server the user runs, using a ready-to-use bundle or a Docker image. The homepage says that keeping data on your own server gives you control of it, but the level of privacy depends on how the instance is set up and hosted. The homepage also says the source code is on GitHub under the AGPL 3.0 license, which conflicts with the open_source field in the directory facts. The public demo is free to try, but the homepage asks visitors to read information about the demo's reliability first.
