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.
