OS2 - Public Digitalization Network in Denmark

Succesful open source is not just about..

..how you develop on your codebase. 

It is also about solid organisation and creating value. 

OS2 is an organisation of public bodies in Denmark where we - together - develop, mature, and maintain public code. 

This way the public bodies obtain a direct ownership over the code, freedom to choose vendors, and devolop (often cheaper) code based on their own needs.



84% of all Danish municipalities
