Submit your proposal for the FOSDEM main track before it’s too late!

The deadline for main track submissions is earlier than it usually is (16th November, that’s in a couple of days!), so don’t be caught out.

For full details on submission information, look at the original call for participation.

Proposals for FOSDEM JUNIOR can now be submitted!

FOSDEM Junior is a specific track to organise workshops and activities for children from age 7 to 17 during the FOSDEM weekend. These activities are for children to learn and get inspired about technology and open source.

We are looking for activities for children from age 7 to 17. These activities are for children to learn and get inspired about technology. Last year’s activities included microcontrollers, game development, embroidery, python programming, mobile application development, music, and data visualization. If you are still unsure if your activity fits FOSDEM Junior, feel free to reach out so we can assist you.

It is important for the children to remain inspired when they return home. So make sure that you give the children something after your activity. This can either be that they can continue working on their project that they worked on during the activity, or in the form of goodies or certifications. Also, if necessary, include information about where the children and their guardians can find resources and tutorials about your project. This is another step towards making sure they continue their technical journey when they return home.

Each room has a maximum capacity of 48 seats, but will be capped at 30 children per activity by the organisers. This is to ensure there is enough seating for both children and their guardians.

Submission process

Please submit your proposals at https://fosdem.org/submit by the 1st of December 2025. If you already have an account from a previous year, you should reuse it so all recorded FOSDEM contributions are associated with your profile.

When submitting your proposal, select ‘Junior’ from the track drop-down menu. Write the desired duration and maximum capacity into the proposal so we can take that into account when planning. Also, please include if you need additional volunteers available during your activity.

Requirements

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 slides and other content provided under the same licence as all FOSDEM content (CC-BY). By participating in FOSDEM you are required to adhere the Code of Conduct.

The FOSDEM junior track is not recorded.

We are pleased to announce the developer rooms that will be organised at FOSDEM 2026.

Developer rooms are assigned to self-organising groups to work together on open source projects, to discuss topics relevant to a broader subset of the community, etc. The individual developer room organisers will issue their calls for participation in the next few days. The list below will be updated accordingly.

Proposals for stands for FOSDEM 2026 can now be submitted!

FOSDEM 2026 will take place at the ULB on the 31st of January and 1st of February 2026.

As has become traditional, we offer free and open source projects a stand to display their work to the audience. You can share information, demo software, interact with your users and developers, give away goodies, sell merchandise or accept donations. All is possible!

We offer you:

• One table (180x80cm) with a set of chairs and a power socket
• Fast wireless internet access

You can choose if you want the spot for the entire conference, or simply for one day. Joint submissions (sharing a table) will be favoured in the process.

After sending your proposal you may add all relevant people, that should be informed, to it.

• Submit your application at https://fosdem.org/stands
• Deadline closes the 9th of November;
• Accepted stands will be announced the 16th of November.

Proposals for developer rooms and main track talks for FOSDEM 2026 can now be submitted!

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-sixth edition will take place on Saturday 31st January and Sunday 1st February 2026 at the usual location, ULB Campus Solbosch in Brussels.

Developer Rooms

Developer rooms are assigned to self-organising groups to work together on open source and free software projects, to discuss topics relevant to a broader subset of the community, etc. Most content should take the form of presentations. Proposals involving collaboration across project or domain boundaries are strongly encouraged.

As usual, we unfortunately have a very hard limit on the number of devrooms we accept due to the realities of the physical space available to us. Every year we must make difficult decisions about which great proposals must be rejected (in the past we could have filled the entire conference with every devroom about a different programming language!). If you submitted a proposal for a devroom in the last few years and got rejected, don’t be disheartened and submit anyway!

This year we are slightly changing the way we make the choices of which devrooms we select. We want to focus a little more on promoting collaboration and community between different projects in niches which don’t normally have their own spaces, rather than large projects with significant corporate backing.

As an example, we want some more weird and wonderful Plan9 ecosystem devrooms.

If you have questions or need help crafting a good submission, contact us at program@fosdem.org.

The deadline for submissions is 12th October.

Key dates:

• 12 October: deadline for developer room proposals
• 26 October: accepted developer rooms announced
• 30 October (or earlier): developer rooms issue Calls for Participation
• 15 December (or earlier): developer rooms publish complete schedules

Main Track Talks

Main track presentations cover topics of interest to a significant part of our audience that do not fit into any of the usual developer rooms, perhaps because of the topic or the large size of the anticipated audience.

This year presentations are either 25 or 50 minutes long including audience questions.

Submission for talks in devrooms will open after devrooms are selected and announced.

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 recordings, slides and other content provided under the same licence as all FOSDEM content (CC-BY). You also accept the FOSDEM Code of Conduct.

The deadline for submissions is 16th November.
