A modern OpenSCAD editor with live preview and AI copilot — runs in your browser or as a desktop app

🌐 Try it now — OpenSCAD Studio is available as a web app (no install needed) or as a macOS desktop app. The web version runs entirely in your browser using WebAssembly.

Desktop: macOS 10.15 (Catalina) or later.

As a software engineer and maker hobbyist, I love OpenSCAD. It allows for precision and maps to my mental model of building things. However, some operations (like rounding with minkowski) are not very intuitive. At work, I often use Cursor and Claude Code for writing code, and found myself plugging my OpenSCAD code into ChatGPT in order to either (1) scaffold out a starting point or (2) fix a confusing issue in my code. I also became frustrated by certain limitations of the OpenSCAD editor, like not being able to easily indent code with the editor commands I'm used to. So I built OpenSCAD Studio, which aims to be something like a Cursor for the language.

• 🌐 Web app - Use directly in your browser at openscad-studio.pages.dev — no install needed
• 🤖 AI copilot - Chat with Claude/GPT to generate and fix code (bring your own API key)
• 🎨 Modern editor - OpenSCAD syntax highlighting, multi-tab editing, format on save, vim mode support
• 📐 2D mode - Dedicated SVG viewer for laser cutting and engraving
• 🖼️ Live 3D preview - Interactive mesh viewer with orbit controls and content-hash caching
• 🔍 Real-time diagnostics - Inline error markers with line/column precision
• ⚙️ Customizer panel - Interactive controls for OpenSCAD parameters with auto-rendering
• 🌈 22+ themes - Popular themes like Catppuccin, Dracula, One Dark Pro, GitHub, Nord, Tokyo Night, and more

Limitations: Special operators (!, #, %, *) preview not yet implemented

Visit openscad-studio.pages.dev. Works in Chrome and Edge (requires SharedArrayBuffer support). No OpenSCAD installation needed — rendering is done via WebAssembly in your browser.

Install via Homebrew:

brew tap zacharyfmarion/openscad-studio
brew install --cask openscad-studio

Or download the latest DMG from GitHub Releases. Requires macOS 10.15 (Catalina) or later.

# Install dependencies
pnpm install

# Run web version in development mode
pnpm web:dev

# Run desktop version in development mode (requires Rust toolchain)
pnpm tauri:dev

# Build for production
pnpm web:build    # Web
pnpm tauri:build  # Desktop

Desktop development requires the Rust toolchain. Web development only needs Node.js 18+ and pnpm.

The AI copilot uses the Vercel AI SDK with streaming support. AI requests are made client-side in both the web app and the Tauri desktop app, and API keys are currently stored in local storage state inside the browser/webview. This is a convenience tradeoff, not backend-style secret isolation.

1. Open Settings (⌘,)
2. Navigate to "AI" tab
3. Enter your Anthropic / OpenAI API key

Supported Providers: All models from the following providers are supported:

• Anthropic
• OpenAI

The AI can:

• View your current code and preview
• Make targeted code changes
• Check for compilation errors
• Generate new OpenSCAD designs from natural language

• CLAUDE.md - Comprehensive guide for AI assistants and contributors
