DEV Community

Hacktoberfest is back for its 13th year, now run by Major League Hacking and DEV.

We're not counting PRs anymore: this October is all about building with open-source AI: agents, open-weight models, your first skills.md, or wherever your curiosity takes you.

Join one of 300+ in-person Fests worldwide or the global online event. Learn more at hacktoberfest.com.
