CADAM v0.3.0 — open-source text-to-CAD web app from YC startup Adam
CADAM is an open-source web app that turns text or image prompts into parametric 3D CAD models. Built by YC W25 startup Adam, it runs in the browser, uses Claude to write OpenSCAD code, and exports STL, SCAD, and DXF under GPL-3.0.
Describe a part in plain English, get a 3D CAD model back — runs entirely in your browser.

What is it?
CADAM is an open-source browser tool from YC W25 startup Adam that turns a natural-language description (or a reference image) into a parametric 3D CAD model. CADAM is GPL-3.0, runs at adam.new/cadam without installing anything, and exports the design as STL, SCAD, or DXF for printing, machining, or further editing.
How does it work?
CADAM sends the user's prompt to a hosted LLM (OpenRouter routes to Anthropic Claude by default) which generates OpenSCAD code. The browser runs OpenSCAD WebAssembly to produce geometry, and Three.js renders the live preview. Users adjust parametric sliders and re-export without leaving the page.
Why does it matter?
Commercial text-to-CAD products are closed-source. CADAM gives makers, mechanical designers, and CAD researchers a runnable reference: a complete client-side stack they can self-host, modify, or wire into their own pipelines. The repo hit 4.3k stars and the Launch HN reached 161 points within a day, signalling demand for an open base in this niche.
