FOSDEM has a particular rhythm. You feel it before the first talk starts. Corridors fill up early, laptops are already open, and conversations resume as if they had only paused a few weeks ago. But this year felt different. The campus was more crowded. The conversations lasted longer. Hallways were packed with people debating architectures, governance, funding, and responsibility. Not in abstract terms, but grounded in concrete choices teams are making right now.

On 31st January and 1st February, the open-source community gathered once again at the ULB campus in Brussels for FOSDEM. For XWiki, this edition confirmed a trend we have been observing for some time: open source is gaining visibility, interest, and momentum. Furthermore, the questions people ask are becoming more structural, more political in the best sense of the word, and more concrete.

This year, we focused our time and energy on the Collaboration and content management devroom and on the community moments around it.

A Collaboration and content management devroom rooted in real concerns

This year’s devroom reflected what we felt across the entire campus: collaboration software is no longer discussed in isolation. Privacy, interoperability, sustainability, accessibility, and digital sovereignty are increasingly interconnected. The sessions moved from concrete product updates to structural ecosystem questions, without losing technical depth.

Below is a quick overview of the talks presented during the day.

CryptPad updates: latest in private real-time collaboration

Presented by Ludovic Dubost, this talk covered recent evolutions in CryptPad, with a focus on improving real-time collaboration while keeping strong privacy guarantees. The session showed how end-to-end encryption and usability continue to evolve together, without compromising CryptPad’s core principles.

XWiki & friends meetup: where the real conversations happen

Saturday evening is when FOSDEM usually exhales. This year, it felt more like a second peak.

Together with our partners from Nextcloud, OpenProject, and Passbolt, we hosted our largest meetup to date at Scott’s Bar in Brussels. More than 200 people showed up, and the space filled quickly. Contributors, maintainers, users, partners, and people discovering these projects for the first time all mixed in the same room.

What made the evening stand out was not the size alone, but the tone. There was no program and nothing to β€œattend.” Conversations formed naturally, often picking up exactly where they had stopped earlier that day in a devroom, a corridor, or over coffee. People compared real setups. They talked openly about migrations that went well and those that did not. They shared funding concerns and questioned assumptions about scale, governance, and long-term ownership.

These were not pitch conversations. They were working conversations. The kind that only happen when people feel comfortable enough to be honest about constraints, trade-offs, and mistakes. The kind that remind you that open source is not just code and licenses, but relationships built over time.

This meetup has quietly become a cornerstone of our FOSDEM presence. It reflects the same shift we felt across the whole weekend: more people, more engagement, and a stronger collective confidence in open source as serious infrastructure.

Take a look at some of the best moments from the meetup!

What this year made clear

FOSDEM 2026 felt like a consolidation. The focus on digital sovereignty was stronger. The questions were sharper. The community was larger and more engaged. All signs point in the same direction: open source is becoming a default choice for organizations that want control, longevity, and clarity.

For XWiki and CryptPad, this is familiar territory. FOSDEM remains the place where these ideas are not just talked about, but tested against reality, challenged by peers, and strengthened by the community.

We are already looking ahead to the next edition. Until then, let's not forget about the traditional XWiki at FOSDEM photo.
