Show HN: Prototyper - the fastest AI software design platform

Hi HN,

I’ve been working the past year on something called Prototyper , and today we’re opening up the new version.

The motivation is simple: whenever I built products in the past, I noticed the best ideas came after the “first version.” You try something, it feels wrong, you change it, repeat. Most tools make that painful. Prototyper is my attempt to make that loop natural—so you can explore ideas quickly instead of forcing them through a rigid workflow.

This release includes:

instant updates (no compile/refresh lag)

simplified UI (months spent just removing steps)

responsive by default

customizable so it bends to your workflow, not the other way around

What I’m most excited about though is under the hood: we’ve built all the core tech in-house (compiler, rendering engine, infra). That means we’re not stuck with the constraints of existing stacks. It’s been a lot of work, but it gives us room to try things that I don’t think anyone else is doing.

This is still early. We’re giving everyone free access for the first week because I’d really love feedback from people who build things for a living.

Curious what you think, and happy to dive into the tech in the comments!
