Hello everyone,

We’re happy to announce that General Registration https://pretix.eu/wikimedia/Hackathon-2026/ for the 2026 Wikimedia Hackathon https://www.mediawiki.org/wiki/Wikimedia_Hackathon_2026 is officially open! The Hackathon will be taking place in person from May 1 - 3, 2026 in Milan, Italy.

The Wikimedia Hackathon is an annual event that brings together the global technical community to connect, hack, and explore new ideas. Experienced technical contributors from all around the world come together to improve the technological infrastructure and software that powers and benefits the Wikimedia projects. The 2026 event is being organized by the Wikimedia Foundation in collaboration with local Wikimedia affiliate, Wikimedia Italia (WMIT) https://meta.wikimedia.org/wiki/Wikimedia_Italia.

During the Hackathon, we will focus on bringing together people who have already contributed to the many technical aspects of Mediawiki and our Wikimedia projects, those who know how to find their way around on our technical ecosystem, and who are able to work or collaborate on projects rather autonomously.

We'll be livestreaming the Hackathon opening ceremony and closing showcase for those unable to attend in person. Local and global communities are also welcome to organize pre-hackathon events or related meetups.

To register for the hackathon: Everyone who attends the event in person is required to register in advance. Registration must be done through Pretix https://pretix.eu/wikimedia/Hackathon-2026/, by selecting “General Registration”. This year we are charging a $2 USD registration fee to minimize the large volume of spam received in previous years. If you have any issues or concerns with the payment, please contact the organizing team.

You can reach the organizing team through email at hackathon@wikimedia.org or comment on the talk page https://www.mediawiki.org/w/index.php?title=Talk:Wikimedia_Hackathon_2026&action=edit&redlink=1. All participants will adhere to the Code of Conduct https://www.mediawiki.org/wiki/Code_of_Conduct for Wikimedia technical spaces and the Friendly Space Policy https://foundation.wikimedia.org/wiki/Policy:Friendly_space_policy.

We hope to see you in May!
