GitCompat - Find Your Perfect Coding Partner

💡 Inspiration

I was pretty new to GitHub and honestly sucked at finding good coding partners. I'd go to hackathons and get stuck with random people — sometimes we clicked, but usually we didn't. I'm okay at backend stuff but put me near CSS and I'm done for.
I kept thinking: "There’s gotta be a better way to find people I actually code well with" instead of just crossing my fingers and hoping for the best.

🚀 What it does

GitCompat looks at two developers' GitHub profiles and tells you if you'd work well together.
It checks out your actual coding — what languages you use, how you collaborate, your commit patterns — and gives you a breakdown of whether you're compatible.

It’s basically like a dating app for developers, except it uses real data instead of just hoping you both like pizza.

🛠️ How we built it

• Built with Next.js for a unified frontend + backend experience.
  
• Pulls developer data from GitHub’s API.
  
• Runs everything through a compatibility algorithm (with some AI help because math is hard).
  
• Uses Google’s Gemini AI to analyze profiles and provide practical, human-readable insights.

⚡ Challenges we ran into

• GitHub’s API is messy — deeply nested data that took ages to untangle.
  
• Getting useful AI responses was tough — early outputs were generic and unhelpful. Needed ~20 prompt rewrites to make it work.
  
• Currently only works for two people at a time, which limits team use cases.

🏆 Accomplishments that we're proud of

• Actually built something functional that gives real compatibility insights.
  
• First time building a full-stack AI-powered app, and it turned out better than expected.
  
• Taking raw GitHub data and making it actionable felt really rewarding.

📚 What we learned

• Next.js is a game-changer for full-stack development.
  
• AI APIs are tricky, but when they work, they’re incredibly powerful.
  
• Building something useful means focusing on real developer workflows, not just nice-sounding features.

🔮 What’s next for GitCompat

• Expand from pairs to whole teams.
  
• Integrate with hackathon platforms so organizers can form stronger teams.
  
• Long-term vision: a networking platform for developers to find long-term coding partners using compatibility data.
