Event Description

Join us for the official Hacktoberfest Hack Day in Budapest on Saturday 31 October!

No matter what stage you're at in your journey, you'll spend the day writing open-source software, exploring developer tools and generative AI, and presenting your work to your peers. You can sign up as an individual, join a group on the day, or arrive with a team of up to four people.

And since our Hack Day coincides with Halloween, we'd love you to dress up! As well as the technical project tracks, we’re holding a Best Halloween Costume competition.

Finally, in addition to the main hack sprint, developers from the local Hungarian open-source ecosystem will actively participate throughout the event. More information will be available soon.
