Hack Spaces at RubyConf 2026

Collaborate, contribute, and shape the future of Ruby.

What are hack spaces?

Hack Spaces (previously called “Hack Day”) is a new event at RubyConf 2026 designed to bring Ruby developers, Rails developers, and open source maintainers together for a day of hands-on collaboration.

This will take place during Community Day on July 15th (the second day of the conference). Community Day will feature workshops, panels, and Hack Day—dedicated spaces for working on the projects that power the Ruby ecosystem. We hope you’ll join us for an experience focused on connection and contribution!

Whether you’re an experienced maintainer or just curious about open source, Hack Spaces offers a unique opportunity to build, learn, and make an impact on the ecosystem. Beginners are welcome (and ENCOURAGED!) to get involved

how community day works

On July 15th, instead of traditional talks, RubyConf will host Community Day. This is a day where attendees can get more hands-on and “choose their own adventure”:

  • Participate in workshops and panels
  • Join Hack Spaces to contribute to open source
  • Connect with peers and mentors in a collaborative environment

Hack Spaces are open to everyone, from first-time contributors to seasoned Rails veterans.

We hope to see you there!
