Online / 6 & 7 February 2021


Presentations - Call for Participation

We now invite proposals for presentations.

FOSDEM offers open source and free software developers a place to meet, share ideas and collaborate. Renowned for being highly developer-oriented, the event brings together some 8000+ geeks from all over the world.

The twenty-first edition will take place Saturday 6th and Sunday 7th February 2021, online. We will be running a variety of streams including Developer Rooms, Main Tracks and Lightning Talks.


All proposals for presentations should be submitted using Pentabarf: If you already created an account in the system for a previous edition, please reuse it rather than re-registering. You can reset your password here:

When making a proposal, please select the appropriate track. If the topic fits into a Developer Room, then please refer to that room's call for papers, listed here and select that room as the "track". Select Lightning Talks for a 15-minute Lightning Talk outside the developer rooms or Main Tracks and Other Topics for everything else.


Submission deadlines vary according to the track.

For Developer Rooms, check the relevant Call for Papers.. The final deadline for Main Track and Other Topics and Lightning Talks is 25th December. Accepted speakers will be notified by 31st December

Given the condensed timescale this year, please note that some programme committees may be reviewing proposals and making decisions on an ongoing basis before the published deadlines. This means that, for the most popular tracks, submitting early may increase your chance of acceptance as later submissions may be competing for fewer remaining places in the schedule, and particular themes for sections of the programme might already have been chosen based upon the range of submissions received earlier.


Accepted speakers will need to prepare, record and upload their presentation during the first two weeks of January. Guidance will be provided. Speakers will need to be in a place with a computer with a reliable internet connection and camera and microphone when their talk is scheduled so they can join a video room and take questions and engage in discussion after their pre-recorded presentation is played.

The conference language is English. All content must relate to Free and Open Source Software. By participating in the event you agree to the publication of your recordings, slides and other content provided under the same licence as all FOSDEM content (CC-BY).
