👋 Hey Product Hunt! We’re excited to launch Multi-File Apps in Code Arena.

AI coding tools often break down once projects go beyond a single file. We built multi-file in Code Arena to solve that, letting developers generate, compare, and iterate on real, multi-file codebases with production-level structure and reliability.

On Code Arena, you can prompt once and see multiple top coding models generate full projects side-by-side, then download the result as a ZIP to run locally or push to GitHub.

We’d love your feedback:

  • What kinds of apps or websites are you building?

  • Which coding models performed best for your build?

  • What additional models or features should we add to Code Arena?


Thanks for checking it out 🙏

@aryanvichare Intriguing, and dying to use this, but I'd really need preview to be able to assess which of the two results is better.

I just tried a prompt, on one side it turned this into 17; the other side 20. What I need, as a low-coder, is the output.

Looks great! 💪 Multi-file generation + side-by-side comparison is such a clean “aha” - most tools demo well on a single file and then fall apart in real projects. What’s been the most common “wow moment” users mention after trying Code Arena? And what’s the biggest friction point you’re still working on? I cross my fingers to you! 🙂

Comparing outputs of different models side by side is a great idea! I’m building an app that ranks places based on online reviews and have been using Claude with skills for both frontend and backend, it’s been solid. Just curious: Can skills or structured context (beyond prompts) be standardized across models for fair comparison? And how does Code Arena help objectively determine the “best” model. Are there measurable benchmarks, evaluation metrics or reports?
