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.

GDPR by designEU hostingUsed by public administrationNo US cloud risk

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.
