Hacktoberfest is an annual event encouraging contributions to open-source projects, skill improvement, and technology enhancement. Last year, over 483,000 pull requests were opened during the festival. Supabase plans various events and activities for this year's Hacktoberfest, inviting participants to contribute to their project and stand a chance to win a limited-edition Hacktoberfest T-shirt. Contributions can be made by developers, designers, or writers, with tasks ranging from creating examples for Blitz.js and Redwood.js to improving UX and adding documentation.
