The must-attend event for open source and digital sovereignty

Over the past six years, Open Source Experience has become the unmissable annual event for open source solutions aimed at digital sovereignty and the resilience of businesses and local authorities. At a time when issues such as technological independence, control over infrastructure, data governance and energy resilience have become strategic priorities, Open Source Experience has established itself as the go-to venue for understanding, decision-making and taking action.

It therefore offers a structured programme for event visitors who are not looking for a specific technology but for an operational solution to their sovereignty and resilience challenges.

Organised by the Systematic Paris-Region open source hub, Open Source Experience brings together over 4,000 professionals and open digital stakeholders over two days.

With no fewer than 130 talks, the event focuses on open-source technologies, solutions and challenges in France and Europe, highlighting the driving role of open-source innovations in the digital transformation of organisations across technologies such as AI, data management, the cloud and cybersecurity.

An international showcase for the technological excellence and economic dynamism of the French open-source sector, the event brings together global technology players, professional associations, businesses and public bodies, a vast network of SMEs and research organisations.

The main themes of the conference 2026

Open source is no longer an option

Open source has become ubiquitous, yet it is still too often underutilised in strategic decision-making. In an era of critical dependencies and new regulatory constraints, it is no longer a matter of believing in it, but of fully embracing it as a lever for control, resilience and sovereignty.

It is against this backdrop that the 2026 programme is set, with the main theme “Open Source is no longer an option”.
