Get involved

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 skills levels are encouraged to complete the challenge.

Hacktoberfest Swag

*To qualify for the official limited edition Hacktoberfest shirt, you must register and make four pull requests between October 1-31. Pull requests can be to any public repo on GitHub, not just the ones with issues labeled Hacktoberfest. If a maintainer reports your pull request as spam, it will not be counted towards your participation for Hacktoberfest. If a maintainer reports behavior that’s not in line with the project’s code of conduct, you will be ineligible to participate.

Event organizers

NOTE: DigitalOcean will be organizing webinars for event organizers in September and early October to discuss Hacktoberfest events.

* Organizing a Hacktoberfest event in October is a great way to foster the open source community.

* Last year, 267 events were organized in 50 countries. This year, let’s work together to bring this celebration to even more people around the world!

* Explore the Hacktoberfest event kit to learn about how to successfully organize a gathering in your community.
