Building UIs with AI feels like magic on day one, but by iteration five, your codebase becomes a tangled mess of inline styles and hallucinated code. floop acts as an open-source anti-corruption layer for AI agents like Cursor and Claude Code. It forces your AI to respect your existing design system, ensuring every generated component is production-ready instead of turning into a disposable prototype.

Hey Hunters! 👋 I'm Marvin. We all love the speed of building with AI, but I was getting incredibly frustrated with the "Disposable Prototype" trap. I would ask an agent to build a UI, and it looked great initially. But a few prompts later, it was inventing new shades of blue, ignoring my component library, and leaving a mess of inline CSS. It was often faster to throw the AI code away and rewrite it than to maintain it. That’s why I built floop. I wanted engineering discipline for AI. floop is a quality loop that sits between your agent and your codebase. If the agent tries to hallucinate a style or raw HTML tag, floop blocks it and forces a rewrite using your actual design system. We're open-sourcing it today to help developers build maintainable apps, not just quick prototypes! Let me know in the comments: What is the worst piece of messy "Frankenstein code" an AI has ever written for you? I’d love to hear your horror stories! 👇
