European Open Source Week 2026

From 26 January to 1 February, thousands of people from Europe and around the world gather in Brussels to discuss open source and open technologies. 

The main attraction is Free and Open Source Software Developers' European Meeting (FOSDEM), Europe’s largest open source conference, which has inspired a range of side events, social activities, and workshops. For those interested in open technology, digital policy, and EU developments, OpenForum Europe’s EU Open Source Policy Summit brings together open source leaders and policymakers. Together, these events make up the EU Open Source Week.
