Event details
Hacktoberfest® is open to everyone in our global community. Whether you’re a developer, student learning to code, event host, or company of any size, you can help drive growth of open source and make positive contributions to an ever-growing community. All backgrounds and skill levels are encouraged to complete the challenge.
- Hacktoberfest is a celebration open to everyone in our global community.
- Pull requests can be made in participating GitHub-hosted repositories/projects, classified with the Hacktoberfest topic.
- You can sign up anytime between October 1 and October 31.
Rules
To earn your Hacktoberfest tee or tree reward, you must register and make four valid pull requests (PRs) between October 1-31 (in any time zone). PRs can be made to participating public repos on GitHub, those that have the Hacktoberfest topic. If a maintainer reports your pull request as spam or behavior not in line with the project’s code of conduct, you will be ineligible to participate. This year, the first 70,000 participants who successfully complete the challenge will be eligible to receive a prize.
