SynapsCAD: Open-Source Desktop App for OpenSCAD with Claude AI Integration
SynapsCAD is an open-source desktop application that combines an OpenSCAD code editor, a real-time 3D viewport, and an AI assistant. The app is free to try and fully open-source.
Key Features
You can write OpenSCAD code and compile it directly to a 3D mesh. The app integrates API support so you can select Claude as your active model to write and modify your 3D CAD code through natural language directly within the application.
Technical Architecture
- Built entirely in Rust
- UI and 3D viewport powered by Bevy 0.15 and egui
- Uses a pure-Rust compilation pipeline with openscad-rs for parsing and csgrs for constructive solid geometry rendering
- No external tools or WASM required
- Async AI network calls handled by Tokio in the background to keep the Bevy render loop smooth
Current Status and Limitations
This is a very early prototype. The OpenSCAD parser/compiler doesn't support everything perfectly yet, so you will hit rough edges with complex scripts. The creator is seeking feedback, architectural critiques, or bug reports—especially specific OpenSCAD snippets that break the compiler.
Availability
Downloads for Windows, Mac, and Linux are available on GitHub: https://github.com/ierror/synaps-cad

Why Your Claude Code UI Output Drifts and How a Structured Spec Fixes It
A developer explains that inconsistent UI output from Claude Code isn't a prompt problem — it's a format problem. Providing exact hex codes, font weights, spacing, screen states, and transitions eliminates drift. They also open-sourced an MCP server that converts screen recordings into structured specs.
