Hacktoberfest 2025 is a month-long, global celebration of open-source software run by DigitalOcean.

It encourages developers, students, and enthusiasts of all skill levels to contribute to open-source projects on platforms like GitHub and GitLab throughout the month of October. Participants submit quality pull/merge requests to improve code, documentation, or other aspects of projects, with the opportunity to earn exclusive rewards like digital badges and t-shirts. It's a key event for learning, community collaboration, and supporting the open-source ecosystem.
