Spacedeck Open

This is the free and open source version of Spacedeck, a web based, real time, collaborative whiteboard application with rich media support. Spacedeck was developed in 6 major releases during Autumn 2011 until the end of 2016 and was originally a commercial SaaS. The developers were Lukas F. Hartmann (mntmn) and Martin Güther (magegu).

The spacedeck.com online service was shut down on May 1st 2018. We decided to open-source Spacedeck to allow educational and other organizations who currently rely on Spacedeck to migrate to a self-hosted or local version.

MNT Research GmbH has restarted development of Spacedeck Open in 2020.

We appreciate filed issues, pull requests and general discussion.
