Features of Open Design:
- Local-First & Open-Source - A fully open-source alternative to Anthropic's Claude Design that runs locally, ensuring data privacy and no vendor lock-in
- 19+ Composable Design Skills - Built-in skills for generating web prototypes, dashboards, mobile apps, slides, images, videos, HyperFrames, and more
- 71+ Brand-Grade Design Systems - Pre-loaded design systems from top brands like Linear, Stripe, Vercel, Airbnb, Tesla, and many others for instant professional-grade styling
- Multi-Agent CLI Support - Auto-detects and works with 16 coding-agent CLIs (Claude Code, Codex, Cursor, Gemini, OpenCode, Qwen, Copilot, etc.) found on your PATH
- BYOK (Bring Your Own Key) Fallback - Protocol-specific API proxy for Anthropic, OpenAI, Azure, and Google Gemini, allowing you to use your own API keys
- Artifact Generation & Export - Generates web, desktop, and mobile prototypes, slides, images, and videos, and exports to HTML, PDF, PPTX, and MP4 formats
- Sandboxed Preview - Every generated artifact renders in a secure, sandboxed iframe for instant preview
- Visual Direction Picker - Offers 5 curated design directions (Editorial Monocle, Modern Minimal, Warm Soft, Tech Utility, Brutalist Experimental) with deterministic palettes and font stacks
- Device Frames - Provides pixel-accurate frames for iPhone 15 Pro, Pixel, iPad Pro, MacBook, and Browser Chrome for realistic mockups
- Live Todo Progress - The agent's plan streams as a live card with real-time status updates, allowing mid-flight redirection
- Discovery Form - A pre-generation form locks the design brief, gathering surface, audience, tone, and brand context before the model writes a single pixel
- Agent Runtime with Real File System - The local daemon spawns the CLI agent in the project folder, granting real Read, Write, Bash, and WebFetch capabilities
- Claude Design Import - Drop a Claude Design export ZIP to parse it into a real project for continued editing
- Persistence with SQLite - Saves projects, conversations, messages, tabs, and templates locally in an SQLite database for seamless continuity
- Lifecycle Management - Single entry point (
- Optional Desktop App - An Electron shell with sandboxed rendering and sidecar IPC for advanced use cases like E2E screenshot testing
- Deployable to Vercel - The web layer can be deployed to Vercel for sharing and collaboration

Features Of CUX:
↔️ Auto-switch on rate limits - when your active account hits the wall, cux rotates to a healthy one and keeps going. Same session. No reload.
💭 Full context preserved - it resumes the exact conversation. Claude remembers everything.
🤝 Proactive threshold swaps - set utilisation limits and cux swaps before you even hit the cap.
🔐 Secure credential handling - Keychain on macOS, Credential Manager on Windows, 0600 files on Linux. Tokens are never logged.
