Hacktoberfest is a time for open source communities and contributors to contribute, improve skills, and build technology through collaborative efforts. Last year's challenge saw 483,127 pull requests opened and 61,871 participants complete it. To get started, simply begin contributing to any open source project, with resources available for first-timers. Supabase is hosting online events, including a live stream on GitHub Open Source Friday, and a Hacktoberfest Online Meetup. The company also has a GitHub project board where contributors can find existing issues or new ideas to work on, with the opportunity to win a limited edition T-Shirt by tagging their contributions with the Hacktoberfest label.
