Open CoDesign is a desktop application that turns prompts into prototypes, slides, and PDFs using AI models of your choice.
The tool addresses the need for a locally-run, model-agnostic alternative to cloud-based design-to-code platforms. It works by accepting a text prompt and generating polished artifacts—prototypes, slides, or documents—rendered live in the interface. The approach centers on local-first execution: you supply your own API keys for Claude, GPT, Gemini, Kimi, GLM, or run models locally via Ollama, meaning your prompts and data stay on your machine rather than being sent to a third-party service.
Developers should choose this tool if they want to avoid vendor lock-in and prefer controlling which model powers their design generation. It suits teams already invested in a particular AI model or those with privacy requirements that rule out cloud-based alternatives. The README explicitly positions it as an open-source alternative to Claude Design, v0 by Vercel, Lovable, Bolt.new, and Figma AI, making it a direct replacement for those workflows if you need local execution and model flexibility.
The project maintains steady development activity with regular commits and releases. The codebase is written in TypeScript and built as an Electron desktop application, indicating a mature technical foundation. Documentation is comprehensive, including a quickstart guide, changelog, and contribution guidelines, suggesting the maintainers are invested in onboarding new users and collaborators.
