OpenCoworkAI released Open CoDesign, an open-source desktop app that generates UI designs, pitch decks, and prototypes from text prompts. Unlike Vercel's v0 or Anthropic's Claude Design, everything runs and stays on your machine. Designs live in a local SQLite database. No account required, no telemetry by default. It's MIT licensed and works on Windows, macOS, and Linux.
The tool uses a bring-your-own-key model. Plug in your existing API key for OpenAI, Anthropic, Google, or DeepSeek. Or skip the cloud entirely and run local models through Ollama. You can watch the agent reason through your request in real time, pause it, or jump in and edit specific parts of a design without regenerating the whole thing. That click-to-edit approach is what separates it from prompt-and-pray tools.
Version 0.1.4 exports to HTML with inlined CSS, PDF via local Chrome, PPTX, ZIP, and Markdown. Token estimates appear before each generation so you see what you're spending. A 0.2 release is planned with what OpenCoworkAI calls "Agentic Design," bringing workspace-backed sessions and permissioned local tools.
It's rough around the edges. Some outputs miss. The developers say it won't replace Figma, and they're right. But for developers who want to spin up a landing page or prototype without sending proprietary designs to a cloud service, it fills a real gap. The fifteen built-in design skill modules and customizable SKILL.md files give it enough flexibility to be useful without the subscription lock-in that comes with incumbent tools.
