Hacktoberfest is underway, featuring an array of impressive open-source projects submitted to the second Supabase Hackathon. The top ten projects across five categories have been selected, with winners and runners-up in each category receiving limited edition swag. All participants will receive a participation tee as a token of appreciation for their contributions. With all projects being open-source, users are encouraged to explore them further and contribute during the second half of Hacktoberfest.
