Open Source Experience 2026

About This Event

Open Source Experience 2026 is a major European event dedicated to open-source technologies, digital sovereignty, resilience, and innovation. Held in Paris, the two-day conference and exhibition brings together open-source developers, technology companies, public administrations, IT decision-makers, researchers, associations, communities, and organizations from across France and Europe. The 2026 edition focuses strongly on the growing importance of technological independence and control over digital infrastructure. Its program covers six principal areas: digital sovereignty and open-source governance; open infrastructure, cloud and sovereign platforms; open AI, models and data; cybersecurity and resilience; sovereign enterprise applications; and open-source culture, skills and careers. More than 6,000 professionals are expected, with approximately 90 exhibitors and 130 conferences and workshops covering technical, strategic, economic, and public-policy aspects of open source. The event provides opportunities to discover projects and technologies, attend technical presentations and roundtables, meet open-source organizations and solution providers, and exchange ideas with members of the European open-source ecosystem. Open Source Experience 2026 is held alongside DEVOPS REX, the French-language DevOps conference focused on practical experience and real-world implementations. The 2026 edition also introduces Lightning Talks and hosts the 10th anniversary of the Acteurs du Libre awards recognizing contributions to the French and European Free Software ecosystem
