👋 Hey Product Hunt!

I’m Manolo (aka. Keff), the creator of Cardboard.js — a tiny UI library born out of frustration with the modern JavaScript ecosystem.

Let’s be real: building simple interfaces shouldn't require learning a new dialect of JavaScript, setting up a full build pipeline, or sacrificing your sanity to the framework gods. Cardboard.js is my attempt to bring things back to basics. No compilers. No “magic.” Just a lightweight reactive layer that works with the platform, not against it.

This is not a React/Vue/Whatever killer. It’s more like a gentle rebellion — for people who want to build UI without joining a cult.

If you’re tired of the hype and just want to build things, I’d love for you to try it out and share your feedback 🙌

Thanks for checking it out!
