Open Source Experience 2026

Europe's open-source trade show, sixth edition, run by Infopro Digital Trade Show and led by the Systematic Paris-Region deep tech cluster. Two days, around 90 exhibitors and 130 conferences and workshops, with more than 6,000 professionals expected. The six 2026 themes are digital sovereignty, governance and open-source business models; open infrastructure, cloud and sovereign platforms; open AI, models, data and sovereign ecosystems; cybersecurity, trust and open-source resilience; sovereign enterprise application platforms; and open-source culture, skills and careers. It runs alongside DEVOPS REX at the same venue on the same dates. 09:00 to 18:00 both days at Paris Expo Porte de Versailles, Hall 5.2, entrance A1. Entry is by visitor badge, requested on the site. Why go: it is the one Paris room each year where the public sector, the large integrators and the open-source vendors all turn up to argue about sovereignty at the same time. Best for CTOs, architects and anyone whose stack decisions now carry a sovereignty column.
