Open CoDesign

Open CoDesign is an open-source desktop design tool that turns prompts into polished prototypes, slide decks, and marketing assets.

Open CoDesign turns prompts into polished prototypes, slide decks, or marketing assets locally using the model you already use. It serves as an open-source alternative to Claude Design, built for people who want the speed of AI-native design tools without cloud-only workflows or single-provider lock-in. As an MIT-licensed desktop app, it features local-first operation and bring-your-soon-key support for models like Claude, GPT, Gemini, DeepSeek, Kimi, GLM, and Ollama, plus direct ChatGPT Plus, Pro, and Team subscription sign-in. Users can also utilize one-click import for existing Claude Code or Codex provider configs. The app includes capabilities such as comment-and-pin region rewriting, AI-tuned sliders for refining parameters, local version history, and live agent activity visibility.
