Welcome to the HCB codebase!
HCB is an open source, safe, and easy-to-use fiscal sponsorship platform for hackathons, Hack Clubs, robotic teams and more. We use it to run our fiscal sponsorship program, we provide high schoolers with a 501(c)(3) status-backed restricted fund for their organization. Behind the scenes, HCB is a Ruby on Rails application (learn more by reading our documentation).
Please email hcb-security@hackclub.com to report the vulnerability. To learn more about security bounties, visit https://security.hackclub.com
To run HCB in a development environment, follow the setup instructions in our documentation. We support development through Codespaces, Docker, and a native setup.
We are so excited for you to join the codebase! We have a getting started
documentation in the dev-docs folder.
All contributors are expected to follow the Hack Club Code of Conduct and Hack Club's contributing guidelines.
Join the #hcb-dev channel on the Hack Club Slack for support.
Happy hacking. β€οΈ
