About OSOR

OSOR is a place where the Free and Open Source software community can come together to publish news, find out about events, find relevant open source software solutions and read about the use of Free and Open Source in public administrations across and beyond Europe. 

OSOR is a trustworthy observatory that provides FOSS expertise and information as well as serves as middle-ground to connect European Public Administrations with other relevant stakeholders. To reach this objective, OSOR promotes the use of Free and Open Source software and supports the community.

EU Commission Launches EU Open Source Solutions Catalogue

The European Commission has officially launched the EU Open Source Solutions Catalogue (EU OSS Catalogue). Developed under the FOSSEPS initiative, the catalogue aims to foster cross-border collaboration by centralising access to open source software solutions tailored to public administrations in EU Member States. With over 640 solutions already available—and more on the way—it promotes transparency, reuse, and efficiency across more than 30 public sector domains.
