We just started registrations for Hacktoberfest , and now is the time to prepare yourself for a month filled with open-source contribution, collaboration, and fun! Hacktoberfest is our month-long celebration of all things open source that kicks off on October 1. Each year, maintainers and contributors come together to contribute to the open-source projects that many individual maintainers, companies (including DigitalOcean), and builders of every skill level rely on. In the 12 years since its inception, Hacktoberfest has exploded from a group of just 676 contributors to a global open-source phenomenon, with over 90,000 participants last year across the globe. That’s a lot of love for open source! Hacktoberfest challenges you to support open-source projects by creating 6 pull or merge requests that project maintainers accept during October. We’re doing awards a little differently this year and bringing back t-shirts! If you’re among the first 10,000 contributors to complete 6 PRs, you will receive an official Hacktoberfest 2025 t-shirt and have a tree planted in your name. We’re also partnering with Holopin this year to share the open-source love digitally. The mascot for this year is Hackstronaut, and all you have to do to get your first Hackstronaut pin is register! As you complete each PR, your pin will move up through different levels, so keep an eye on your inbox to claim them. Starting today, visit Hacktoberfest. com to get excited about making your contributions or prepare your project to receive some. Also, mark your calendar for the virtual kickoff event on October 1. The Hacktoberfest website has all the information you need to get started.
