**Type:** Announcement

## Summary

Supabase has launched Holiday Hackdays, a ten-day virtual hackathon running from December 3rd to December 12th. The event invites participants to build open-source projects using Supabase features, following the recent introduction of row-level security for the Realtime API. Teams of one to five developers may build applications using any programming language or framework provided the code and design elements are created during the hackathon. Submissions will be evaluated on criteria such as inventiveness, technical execution, visual polish, and Supabase integration, with prizes dedicated to Realtime API usage and holiday-themed concepts. Members of the Supabase team will also take part by developing an open-source advent calendar showcasing community content.

## Context

Supabase recently launched row-level security for its Realtime API and concluded its Launch Week, creating an opportunity to engage the developer community in building projects with the platform.

## Approach / What changed

Supabase structured a ten-day community hackathon called Holiday Hackdays, setting open-source project submission requirements, team size rules, and judging criteria focused on Supabase feature implementation.

## Takeaways

- All Holiday Hackdays project entries must be open source with accessible repository links.
- Hackathon teams are limited to one to five members, and all code and design elements must be created during the event window.
- Projects must use Supabase in some capacity, with distinct prize categories for Realtime API usage and holiday-themed builds.
