Design OS - Gemini Edition is a modified, cost-efficient version of Design OS. It helps you define your product vision, structure your data model, design your UI, and export production-ready components using Gemini CLI instead of Claude Code.

Rather than jumping straight into code, you work through a guided process that captures what you're building and why—then hands off everything your coding agent needs to build it right.

The original Design OS is an incredible tool, but it relies on Claude Code. This version was created to:

• Reduce Costs: Leverage the generous free tier of Google's Gemini models via the CLI.
• Local Integration: Use a local bridge server to communicate with the gemini-cli tool directly.
• Persian Support: Optimized for developers working in multilingual (RTL/LTR) environments.

1. Product Planning — Define your vision, break down your roadmap, and model your data
2. Design System — Choose colors, typography, and design your application shell
3. Section Design — For each feature area: specify requirements, generate sample data, and design the screens
4. Export — Generate a complete handoff package for implementation

You must have the official Gemini CLI installed and configured on your system.

# Install globally with npm
npm install -g @google/gemini-cli

# Or run instantly with npx (no installation required)
# Note: The bridge server expects a global 'gemini' command by default.

The bridge server in this project specifically uses the gemini -p "..." --output-format json pattern, which is fully supported by the official CLI.

git clone https://github.com/yourusername/design-os-gemini.git
cd design-os-gemini
npm install

Design OS requires both the client and the bridge server to be running:

npm run dev

This will start:

• Client: http://localhost:5173 (Vite)
• Bridge Server: http://localhost:3001 (Express bridge to Gemini CLI)

Original tool created by Brian Casel, the creator of Builder Methods. This fork adapts the intelligence engine to use Gemini for enhanced accessibility and cost-efficiency.
