An open-source, self-hosted collaborative whiteboard for diagrams, workshops, and visual thinking. - kevcool/DryErase

For those interested. Newly released, self-hosted, team white boarding and collaboration tool on GitHub. There’s a lot of commercial collaboration tools out there but this is free to download, modify, host etc. (released as AGPLv3). This is initial release and can benefit from future enhancements like RBAC, etc. Some of that intent is in the roadmap. Collaborators are welcome. Cheers!
