Open-source alternative to: Claude Design · v0 by Vercel · Lovable · Bolt.new · Figma AI
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). One-click import of your existing Claude Code or Codex API key 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:

Open source, desktop-native, and built for people who do not want their design workflow locked to one model or one cloud.

After each tag push, CI auto-syncs SHAs back into packaging/ and (once the winget PR merges) auto-opens downstream bumps. Every packaging/*/README.md documents its own mirror flow.
v0.1 note: installers are unsigned. On macOS Sequoia 15+ right-click → Open no longer bypasses Gatekeeper, and "Open Anyway" in System Settings often fails. Reliable one-liner:
xattr -cr "/Applications/Open CoDesign.app"Then double-click normally. (Older 0.1.x builds are installed as
/Applications/open-codesign.app.) On Windows: SmartScreen → More info → Run anyway.Want a verified build? Compile from source — see CONTRIBUTING.md.
On first launch, Open CoDesign opens the Settings page. Paste any supported provider key:
sk-ant-…)sk-…)Credentials stay in ~/.config/open-codesign/config.toml (file mode 0600, same convention as Claude Code, Codex, and gh CLI). Nothing leaves your machine unless your chosen model provider requires it.
Pick one of fifteen built-in demos — landing page, dashboard, pitch slide, pricing, mobile app, chat UI, event calendar, blog article, receipt/invoice, portfolio, settings panel, and more — or describe your own. A sandboxed prototype appears in seconds.
Already using Claude Code or Codex? Your providers, models, and API keys import in one click, with no copy-paste and no need to re-enter settings:
Generic AI tools tend to produce generic output. Open CoDesign ships with twelve built-in design skill modules — slide decks, dashboards, landing pages, SVG charts, gl
