Claude Design is great, but a lot of people don’t want to be locked into a single ecosystem. Open CoDesign offers an open-source AI design workflow: local-first, BYOK (Bring Your Own Key), built-in multi-model support. It can connect to Claude, GPT, Gemini, DeepSeek, Kimi, GLM, Ollama, or any OpenAI-compatible endpoint. After entering a prompt, it can generate deliverables like prototypes, slides, PDFs, ZIP files, and more. The focus is on breaking AI design tools out of 'platform capabilities' and turning them into a locally-run, model-agnostic, extensible open-source desktop application.
