What it is
Turn a prompt into a polished prototype, slide deck, or marketing asset, locally, with the model you already use.
Open CoDesign is the open-source Claude Design alternative — built for people who want the speed of AI-native design tools without subscription lock-in, cloud-only workflows, or being forced onto a single provider. An MIT-licensed desktop app, local-first from day one, with BYOK for any model (Claude, GPT, Gemini, DeepSeek, Kimi, GLM, Ollama, or any OpenAI-compatible endpoint) plus direct ChatGPT Plus / Pro / Team subscription sign-in for Codex models. One-click import of existing Claude Code or Codex provider configs, or one-click ChatGPT sign-in, gets you running in under 90 seconds.

From a blank prompt to a finished artifact, the agent plans, writes, self-checks, and ships something with hover states, tabs, and empty states already wired up:
Why people star it
- Runs on your laptop — no mandatory cloud workspace
- Works with your model — Claude, GPT, Gemini, Ollama, OpenRouter, and more
- Exports real files — HTML, PDF, PPTX, ZIP, Markdown
- Shows its work — live agent activity, visible tool calls, interruptible generation
Why Open CoDesign?
Open source, desktop-native, and built for people who do not want their design workflow locked to one model or one cloud.
