ZuriHac 2026 will take place Saturday 6 June – Monday 8 June 2025 as a physical event at the Rapperswil-Jona campus of the OST. ZuriHac is the biggest Haskell / Functional Programming 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!
This year’s keynote speakers include Simon Peyton Jones (one of the creators of Haskell), Evan Czaplicki (the creator of the Elm programming language), and GarrickChin (developer of the “Defect Process” 2D hack n' slash game on Steam). We also have a track on Category Theory, given by Jencel Panic (author of “Category Theory Illustrated”), as well as a track on rolling your own dependent types given by Andres Löh and Andrea Vezzosi. The Beginners’ Track this year will be given by Michael Sperber (CEO of Active Group and author of “Schreib dein Program”), who will also talk about teaching programming. Our website https://zurihac.info contains further information on keynotes and tracks and will be updated regularly.
