Our proven groupware allows you to create the foundations of digital sovereignty. Digital workplaces are most effective when they integrate all your applications and specialist processes.

Our mission for more than 20 years:

Open-source software alternatives for true digital independence.

Providers of proprietary software are in control of your data because the standards, interfaces and algorithms are not available. This creates lasting dependency.

Independence through transparency

Break free from this dependency with open-source software. When every line of software can be checked by your IT experts, you gain security over your systems and the data related to your customers, citizens, and employees.

The advantages are apparent

Freedom to develop the
IT strategy you need

Huge savings
in license costs

Self-determination and control when backing up data

Data center or cloud - you decide

You decide where your data is stored and who can access it - regardless of whether it is cloud-based, in your own data center, that of a service provider or on premise.
