ZuriHac 2025

ZuriHac is the biggest Haskell community event in the world: a completely free, three-day grassroots coding festival co-organized by the Zürich Friends of Haskell and the OST Eastern Switzerland University of Applied Science. It is not your standard conference with papers and presentations, but features fantastic keynotes, hands-on tracks, hacking on many of your favourite projects, and of course lots of socializing!

ZuriHac takes place Saturday 7 June — Monday 9 June 2025 as a physical event at the beautiful Rapperswil-Jona campus of OST located right next to lake Zürich. We hope to see you there!

Registration will open at the end of January!

Speakers

Rebecca Skinner

Rebecca is a Haskell programmer at Mercury and the author of Effective Haskell. She currently chairs the Haskell.org committee.

Lennart Augustsson

Lennart Augustsson works at Epic Games and was previously a lecturer at Chalmers University of Technology. He likely holds the world record for the most Haskell compiler implementations.

Brent Yorgey

Brent Yorgey is an assistant professor at Hendrix College. He is one of the people behind diagrams, which you may have used before. Currently, he is working on a 2D programming game called Swarm.

ZuriHac Prelude

The Haskell Ecosystem Workshop and the Haskell Implementors’ Workshop will take place on the two days just prior to ZuriHac 2025, June 5 & 6 2025. Organised by the Haskell Foundation and the OST Eastern Switzerland University of Applied Sciences in Rapperswil, these events are co-located with the ZuriHac.

Haskell Ecosystem Workshop

The Haskell Ecosystem Workshop is for those of you who want to gain a deeper understanding of the Haskell tooling ecosystem, whether to better leverage those tools or to become contributors. Contact Jose Calderon, executive director of the Haskell Foundation, if you have any questions.

Haskell Implementors’ Workshop

The Haskell Implementors’ Workshop (HIW) is a community event for people involved in the design and development of Haskell implementations, tools, libraries, and supporting infrastructure to share their work and to discuss future directions and collaborations with others. Until 2024, the HIW used to be co-located with ICFP (International Conference on Functional Programming). In 2025, it will be co-located with ZuriHac to be accessible to a broader audience. Contact Andreas Herrmann, the HIW program chair, if you have any questions.
