Workplace & Collaboration
A digital workplace that's actually yours.
OpenDesk is the open-source suite Germany's public administration runs in production. We bring it to your company: in your branding, on EU servers or your own hardware, no lock-in.
Why an open alternative?
- Schrems II and the CLOUD Act: US authorities can reach data in US clouds, even when the servers sit in the EU.
- Commercial suite licensing grows per user and month. Open source costs setup once, then predictable operations.
- Open formats instead of lock-in: your data stays exportable, switching providers remains possible at any time.
- Clarity on AI: with a self-operated suite you know exactly what happens with your data and who trains on what.
