Code Arena: – Compare multiple AI-built apps from a single prompt

Summary: Code Arena lets developers generate and compare multi-file apps or websites from a single prompt using top AI coding models. It supports side-by-side output comparison and exports ready-to-run code to GitHub or IDEs, addressing limitations of single-file AI tools.

What it does

It generates full multi-file projects from one prompt across multiple AI models, displaying results side-by-side for comparison and allowing export as ZIP or direct GitHub push.

Who it's for

Developers needing to create, compare, and iterate on multi-file AI-generated codebases with production-level structure.

Why it matters

It solves the issue of AI coding tools failing on multi-file projects by enabling reliable generation and comparison of complete codebases.
