Hi HN,I’m Thijs, new to the community and excited (and a bit nervous) to share what I’ve been working on: it's called Prototyper.The motivation: I was curious how much more "taste" you could get out of an LLM if you built the entire infra yourself: tool calling, code execution, rendering—instead of layering on top of existing stacks. Over the past year I built a custom compiler, runtime, and design engine from scratch to see if this could make LLM-driven design genuinely better.A few details:- Own compiler + code runtime → no shadcn, no third-party UI kit, no external execution layer.- Instant feedback (no compile/refresh lag).- Deterministic design controls that integrate with llm-generated

As a business in show hn launch, Prototyper is listed here with the public details available about it.

Its current recorded stage is Show HN launch.
