Collaborate, contribute, and shape the future of Rails.
Hack Spaces (previously called "Hack Day") is a new event at RailsConf 2025 designed to bring Rails developers and open source maintainers together for a day of hands-on collaboration.
This will take place during Community Day on July 9th (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 Rails 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.
The following open source maintainers will be LIVE on the ground at RailsConf 2025 during Hack Spaces, sharing their projects and engaging with the community. If you’re interested in getting involved with any of these projects, we recommend checking out their repos and digging in before the event (although this is not required)!
