FOSDEM is the biggest free and non-commercial event organized by and for the community. Its goal is to provide Free and Open Source developers a place to meet. No registration necessary.



Over the years, the schedule of FOSDEM evolved into a format that provides different sort of talks and sessions, grouped as follows:

Main Tracks

The Main Tracks consist of 6 topics (that change each year) for which the FOSDEM organisers invite 3 speakers (more or less, subject to slight variations) who are project leads or active contributors.

Those 45 minute presentations are held in the largest rooms of the venue, namely Janson and K1.105.

Lightning Talks

The Lightning Talks sport a highly appreciated format that consists in many 15 minute talks on a large spectrum of topics (all being directly related to open source or Free Software projects, obviously). The nice thing about having such a short time is that speakers tend to get to the point very directly, and that you can hear about a lot of projects and initiatives.

All those talks are held in the room H.2215 (Ferrer), next to the main Infodesk in the H building.

Developer Rooms

The "DevRooms" are the most collaborative part of the conference: opensource and Free Software projects contact the FOSDEM organisation team during a call for papers phase in order to request a room for their project. When they are being granted one, they work out their own schedule of talks and activities, without the FOSDEM organisation team being further involved.

As FOSDEM is primarily a perfect occasion for cross-pollination and interaction between projects and communities, as so many key projects and contributors are present, several such initiatives have started to take place over the years.

The devrooms are spread across many rooms in the H, K and AW buildings as well as in Lameere, Chavanne and many others.
