Team Members must create a GitHub account at, or log in with an existing GitHub account. There is no charge for creating a GitHub account. This will enable teams to receive important updates and meet HACC submission.  Each team member will need to supply this existing or new account to team captain so that they can be linked to their team’s repository by our administrator.

By submitting a proof of concept or prototype, teams make the code open source and grant permission to the State of Hawaii to duplicate, reuse or re-purpose any portion of the submission code, visual design elements or concepts.

DevPost – is the primary tool used by hackathons to promote their events, track team activities and results

The Team Captain is required to register for a DevPost account at, as that will be used for submissions to the HACC DevPost site.

Please remember to make sure your code is deployed to a public location prior to the Tech Evaluation.  This allows tech judges to evaluate how well your code is working not just reviewing the lines of code.  Steps on how to access this demo location and log in should be included in your DevPost details.
