We are so excited to finally announce the winners of the GitHub Finish-Up-A-Thon Challenge, our celebration of finishing what you started by reviving abandoned side projects, hackathon creations, and long-forgotten repos with help from GitHub Copilot.
First things first: thank you all so much for your patience. We know this announcement took longer than expected, and we're grateful you stuck with us while we gave every submission the careful review it deserved.
The comeback stories you shared were incredible. Your work showed us that no project is ever truly dead, it's just waiting for its second act.
Now, let's celebrate our ten winners!
