What is it?
open-codesign is an MIT-licensed TypeScript desktop app from OpenCoworkAI, created April 18, 2026. It is an open-source alternative to Anthropic's Claude Design tool for turning natural-language prompts into visual prototypes, slide decks, or marketing assets.
How does it work?
Users import their Claude Code, Codex, or any OpenAI-compatible API key in one click. The app supports multiple model backends — Claude, GPT, Gemini, Kimi, GLM, and Ollama for local models — and processes everything locally with no data transmitted to the app developer. Version 0.1.4 (April 23) added AI image generation, ChatGPT Plus/Codex subscription support, and a CLIProxyAPI import flow.
Why does it matter?
Claude Design is closed-source and cloud-only. open-codesign provides the same prompt-to-visual-artifact capability under an MIT license that users can self-host, audit, and extend, with no vendor lock-in and privacy-first local execution.
Who is it for?
Designers, marketers, and developers who want AI-powered prototyping without cloud dependency or a specific model provider subscription.
