What is ZuriHac?

ZuriHac is the biggest Haskell Hackathon in the world: a completely free, three-day grassroots coding festival organized by Zürich Friends of Haskell. It features fantastic keynotes, interesting tracks, and of course lots of hacking and socializing!

ZuriHac takes place Friday 12 June — Sunday 14 June 2020.

Holding an event for 500 people in a physical location is clearly not an option this year. Instead, we are happy to inform you that the hackathon will take place as an online event. Read on below for the details, we're very eager to tell you how we intend to make it into a great event.

What will the online version look like?

For the talks, we are streaming them live on YouTube. We will even hold the usual Q&A at the end, where our friendly moderators will pass your questions from the chat to the speaker.

For the general hacking and socializing, we will be using Discord. It provides both chat channels like Slack and IRC, as well as voice channels with optional video/screen sharing. This gives us an online space where we can:

We also plan to host the beginner and advanced tracks online. More info about that will follow!

How do I attend?

I'm glad you asked! You still need to register, so that we can provide a good experience to everybody. If you're privacy minded, feel free to choose any username you want.

After you register, you will find an invite link to our Discord server on your registration page.

Finally, make sure to head over to our projects page, and have a look at what interests you. If you submit your own project, we will even create a channel on Discord just for you!

But what about my T-Shirt?

The economics of an online conference are very different from an on-site event, so we have decided to offer reimbursements to all our sponsors. This means we cannot offer any free T-Shirts this year.

However, we've seen in our post-events surveys that a lot of people really like the T-Shirt! That is why we have opened a webshop this year, so you can still get the ZuriHac swag you deserve.

Take me to the webshop

All profits we make on these T-Shirts will be donated to a COVID-19 related charity. Shipping may be slow due to the pandemic, and we are obviously also very new to selling items online, so please be patient.



This timetable is very preliminary. It will be updated and more details will be added as we get closer to the event.

There is also a public Google calendar that you can use.

Philip Wadler
Philip Wadler

Philip is a professor at the University of Edinburgh who played a critical role in the design of Haskell and worked on many things that we now take for granted such as type classes and Monads. He also made important contributions to languages other than Haskell—for example introducing Generics in Java 5.

Emily Pillmore

More speakers will be announced as we get closer to the event.


Advanced track

The Haskell experts from Well-Typed will teach a two-part course in the advanced track. The two sessions cover different subjects and are completely independent. They will take place on Friday and Saturday afternoon. The exact topics will be announced here before the event.

Beginner track

We're excited that Julie Moronuki from Joy of Haskell and Type Classes will be teaching the beginners course again this year.

The beginners course focuses on Haskell language fundamentals and requires no prior experience with the language. It will take place in two parts, on Friday and Saturday afternoon. We will post detailed installation instructions here prior to the event, so you will be able to dive right in!
