Building HappyHands

About

I'm building HappyHands to help people improve the websites they create with AI. It connects design review, design-system extraction, scoped code changes, and before-and-after verification in a local workflow. Currently sharing the free, open-source release and learning from real projects. Interested in thoughtful interfaces, design systems, and better tools for independent makers.

HappyHands - Open-source design reviews for your AI-built website

HappyHands helps you improve an existing website with your coding agent. Review pages and interactions, extract design tokens and components, confirm what to change, then compare the result with before-and-after evidence. Free, open source, and run locally with your own agent setup.
