Support open source and earn a limited edition T-shirt!Start Hacking
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 open to everyone in our global community!
- Pull requests can be made in any GitHub-hosted repositories/projects.
- Sign up anytime between October 1 and October 31.
To qualify for the official limited edition Hacktoberfest shirt, you must register and make four pull requests (PRs) between October 1-31 (in any time zone). PRs can be made to any public repo on GitHub, not only the ones with issues labeled Hacktoberfest. 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 50,000 participants who successfully complete the challenge will earn a T-shirt.

Tomorrow automatically calculates the climate \ impact of your daily choices by connecting to apps and \ services you already use.
Pledge your respect and appreciation for contributors \ of all kinds to your open source project.

Words from our sponsors
We’re so excited to partner with DEV – an open source community platform built for developers of all backgrounds and experience levels – for this year’s Hacktoberfest. As a torch-bearer for open source, transparency, and inclusion in tech, DEV fully embodies the Hacktoberfest values. Check out the #Hacktoberfest tag on DEV for announcements and resources before, during, and after the event.
As participants long before we became sponsors, we’re thankful to our friends at DigitalOcean for creating Hacktoberfest. As an advocate of developers and startups, their cloud platform uniquely hits on both simplicity and scalability. And their Community platform has become a global resource for education on development and DevOps topics, further illustrating that they, too, are stewards of open source.
