Open Source Experience 2025: 4,000 professionals, 130 conferences, Europe's open future

Open Source Experience 2025

Next week, we will be at the City of Science and Industry for Open Source Experience 2025, one of Europe’s largest free‑software events. And the numbers speak for themselves:

  • 4,000 professionals expected over 2 days.
  • 130 conferences and round‑tables on the program.
  • 145 speakers who will share their expertise.
  • 90 exhibitors around open‑source technologies: vendors, integrators, associations…
  • A “European village” animated by 8 major European free‑software companies, in partnership with APELL.

This is where those who develop, deploy, fund and teach Open Source meet. Where alliances, projects… sometimes the next standards are born. And, as every year, we will be there out of conviction.

Because open source is not just a development model.
It is a vision of society, where value is built together.
And because in France we have the talent, the infrastructure and the desire to build a free… and sovereign digital ecosystem.

December 10 & 11 – City of Science (Paris)
2 LINAGORA stands
2 workshops (Benjamin Bellamy and Benjamin André)
concrete demonstrations of TwakeAI, OpenRAG, etc...

We have a lot to show… and even more to build, with you.

Come meet us. Let’s talk about what really matters: how to make free software… a sustainable model.
