We are very excited to organize and present to you the inaugural postmarketOS conference in Autumn later this year. It's the perfect place for discussions, workshops and collaboration in the postmarketOS and Linux Mobile space, including our upstream projects. We want to connect developers and users with each other, provide room for technological deep-dives, governance round-tables, hands-on learning and hacking sessions.
📍 Location
The conference will take place in Aachen, a city at the tripoint of Germany, Belgium and The Netherlands, on the premises of RWTH Aachen University, Germany's second largest technical university. We will welcome you in the "B-IT" rooms 5053.1 and 5053.2 in building E2 of the Informatikzentrum (center for computer science).
Address: Ahornstraße 55, 52074 Aachen, Germany (OpenStreetMap)
🎫 Tickets
Participation in the conference is free of charge, but you need to register your attendance in advance. This is because we only have limited space for guests. You will be able to register for a free ticket in the upcoming weeks, the time for registration and further details will be announced via our communication channels on the Fediverse and Matrix.
You will also find the link to the registration form here when it's ready!
Students of RWTH Aachen University do not need to register and are welcome to show up at the conference at any time.
👩🏫 Participate
If you're working on postmarketOS, any of our upstream projects or topics in the Linux Mobile space, we'd be glad to hear from you at the conference! We're able to offer various timeslots for
- Presentations
- Workshops
- Roundtable discussions
and more! We will try to record all presentations and possibly also live-stream them. If you're unsure whether your proposal is a good fit, please submit it anyways. We'll review all of them and want to cover a broad spectrum, since our audience is very diverse: you'll be presenting to kernel hackers, desktop environment maintainers, activists and end users, all at once. Your proposal does not need to cater to everybody, but we will try to find a mix with something for everyone!
The CfP is already open and closes on June 30th. You can find it here.

From Austria, ÖBB Nightjet services provide a direct connection from Vienna to Aachen via Munich on a few days every week.
In Germany, the regional express lines RE 1, 4 and 9 connect Aachen with Cologne, Düsseldorf, Dortmund, Essen, Wuppertal and Hamm every hour. The ICE on the line Frankfurt - Cologne - Brussels stops here every two hours, and a handful of ICE services from Berlin via Hannover and Cologne or Mönchengladbach end here every day.
If you're flying by plane, the nearest airports are Cologne/Bonn (CGN), Düsseldorf (DUS) and Brussels (BRU), all of them little over an hour away from Aachen.
