Be a key part of Hacktoberfest 2025—become a sponsor

Hacktoberfest couldn’t exist without support from incredible sponsors who love open source. Becoming a Hacktoberfest sponsor comes with a lot of benefits:

  • Reach highly engaged developers

    Showcase your brand across our global platform, Discord, GitHub/GitLab integrations, and the websites of thousands of open-source projects.

  • Build developer goodwill

    Hacktoberfest is about giving back. By sponsoring, you align your brand with a global movement focused on education, inclusion, and innovation.

  • Drive product awareness

    Sponsors are invited to host events, promote tools, and offer perks, all while engaging directly with their core developer audience.

  • Targeted impact

    The benefits of reaching a dedicated, engaged developer audience speak for themselves—and we’re offering tiered sponsorships that help you get the most bang for your buck. Plus, this year, get a chance to demo your product in front of excited devs in one of our community events.

Let’s build the future of open source, together. Whether you’re launching a developer tool, hiring open-source contributors, or scaling a community, Hacktoberfest gives you a trusted platform to do it in a way that gets users excited.
