For the Love of Code
For the Love of Code is a global summer-long hackathon celebrating joyful, ridiculous, and wildly creative coding projects. Whether you’re building a bot that reviews your PRs like a concerned parent, finally doing something with that domain name you bought at 2AM, or inventing a programming language where every keyword is an emoji—this is your excuse to build the thing.
No startup pitches. No pressure. Just vibes.
Enter solo or with friends, and submit your project by September 22. Winners get Copilot Pro+, eternal nerd cred, and a feature on the GitHub blog.

Recurse ML
What is Recurse?
Recurse build machine learning models that find bugs in code. This can be in the code that humans write, or that AI generates. We have built two tools for each use case.
rml CLI tool
rml checks locally staged changes for bugs. It integrates with AI agents like Cursor and Claude Code acting as a self-healing feedback loop for them to fix their mistakes.
GitHub App
It automatically reviews pull requests for breaking changes when submitted to your codebase.
