A digital workplace that's actually yours.
OpenDesk is the open-source suite Germany's federal administration runs in production. We bring it to your company - in your colours, on your server, no lock-in.
Why an open alternative?
- Schrems II & CLOUD Act: US authorities can theoretically reach data in US clouds, even when servers sit in the EU.
- Commercial cloud-suite licensing scales per user and month. Open source costs setup once, then operation.
- Avoid vendor lock-in: open-source data lives in open formats and stays exportable.
- AI clarity: with a self-operated open-source suite you know exactly what happens with your data and who trains on what.
