Protoloop — an agentic CAD / 3D-model studio for macOS (Apple Silicon). Describe a part in plain language; Claude plans it, writes parametric CAD source, and renders a live 3D model you can rotate, measure, tune with sliders, and export.
Download
Protoloop-0.1.0-arm64.dmg— macOS on Apple Silicon (M1/M2/M3/M4).
Install
The app is signed but not notarized, so Gatekeeper will warn on first launch:
- Open the DMG and drag Protoloop to Applications.
- Right-click → Open → Open the first time (only needed once).
Requirements
- The Claude Code CLI (
claude) signed in — default backend, no API key needed — or an Anthropic API key in Settings. - OpenSCAD (
brew install --cask openscad) for the OpenSCAD engine. JSCAD needs nothing extra; CADQuery/build123d install on demand from Settings (needs Python 3.10–3.13).
🤖 Built with Claude Code (Opus 4.8).
