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

After each stable tag push, CI syncs SHAs back into packaging/ and publishes downstream Homebrew/Scoop updates when the repo secrets are configured. The first winget submission is in review; once Microsoft accepts the package, future winget bumps can be automated from the release workflow. Every packaging/*/README.md documents its own channel.
Unsigned installer note: installers are not notarized or Authenticode-signed yet. 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. Pick the path that matches how you already use models:
- ChatGPT subscription — sign in with ChatGPT to use Codex models without pasting an API key.
- API key — paste Anthropic (
sk-ant-...), OpenAI (sk-...), Google Gemini, OpenRouter, SiliconFlow, DeepSeek, or another supported provider key. - Local / keyless — use Ollama or an IP-allowlisted OpenAI-compatible gateway.
Credentials stay in ~/.config/open-codesign/config.toml and the ChatGPT OAuth token store under the app config directory. Nothing leaves your machine unless your chosen model route 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? API-key provider configs import in one click, with no copy-paste and no need to re-enter settings. If you use Codex through ChatGPT subscription login, sign in directly from 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, glassmorphism, editorial typography, heroes, pricing, footers, chat UIs, data tables, and calendars — plus a built-in taste layer that steers the model toward considered typography, purposeful whitespace, and meaningful color.
Every skill is available in every generation. Before the model writes a line of CSS, it selects the skills that fit the brief and reasons through layout intent, design-system coherence, and contrast, bringing higher-quality design behavior to whichever model you choose.
Add a SKILL.md to any project to teach the model your own taste.
- Unified provider model — Anthropic, OpenAI, Gemini, DeepSeek, OpenRouter, SiliconFlow, local Ollama, or any OpenAI-compatible relay; keyless (IP-allowlisted) proxies supported
- One-click import and sign-in — bring Claude Code / Codex API-key provider configs across, or sign in with ChatGPT subscription for Codex models
- Dynamic model picker — every provider exposes its real model catalogue, not a hardcoded shortlist
- Prompt → HTML or JSX/React component prototype, rendered in a sandboxed iframe (vendored React 18 + Babel on-device)
- Fifteen built-in demos + twelve design skill modules — ready-to-edit starting points for common design briefs
- Live agent panel — watch tool calls stream in real time as the model edits files
- AI image generation — opt-in bitmap assets for heroes, product shots, backgrounds, and illustrations via OpenAI, OpenRouter, or signed-in ChatGPT subscription
- AI-generated sliders — the model emits the parameters worth tweaking (color, spacing, font)
- Comment mode — click any element in the preview to drop a pin, leave a note, and let the model rewrite only that region
- Generation cancellation — stop mid-stream without losing prior turns
- Phone / tablet / desktop preview — true responsive frames, switch with one click
- Files panel — inspect multi-file artifacts (HTML, CSS, JS) before export
- Instant design switching — the last five designs keep their preview iframes alive, so Hub ↔ Workspace and sidebar navigation stay zero-delay
- Connection diagnostic panel — one-click test for any provider, with actionable errors
- Per-generation token counter — see exactly how many tokens each run cost in the sidebar
- Settings with four tabs — Models, Appearance, Storage, and Advanced
- Light + dark themes, EN + 简体中文 UI with live toggle
- Five export formats — HTML (inlined CSS), PDF (local Chrome), PPTX, ZIP, Markdown
- GitHub Release pipeline — unsigned DMG (macOS), EXE (Windows), AppImage (Linux). Code-signing lands in v0.5 along with opt-in auto-update
Current release: v0.2.0. The current release theme is Agentic Design.
v0.2 turns Open CoDesign from a one-shot generator into a local design agent with a real workspace:
- Design as session — every design is a pi session with JSONL history and a workspace folder on disk
- Permissioned agent loop — pi built-ins for read, write, edit, bash, grep, find, and ls, gated by Open CoDesign's permission UI
- Design tools on demand —
ask,scaffold,skill,preview,gen_image,tweaks,todos, anddone DESIGN.mdas shared memory — brand tokens and design-system decisions become editable files, not model memory- v0.1 migration path — existing SQLite designs migrate into workspaces and session history
- AI image generation — opt-in bitmap assets through OpenAI image models or OpenRouter image models
- ChatGPT Plus / Codex subscription login — one-click OAuth for users who do not want to paste an API key
- CLIProxyAPI one-click import — auto-detect a running local proxy and bring it into Settings
- API config hardening — clearer relay diagnostics for timeouts, SSE truncation, missing
/models, and incompatible Messages APIs
- Renderer polish for the new
ask,preview, tweaks, and process-management surfaces - Cost transparency — pre-generation estimate + weekly budget (per-generation token count already shipped)
- Version snapshots + side-by-side diff
- Three-style parallel exploration
- Codebase → design system (token extraction)
- Code-signing (Apple ID + Authenticode) + opt-in auto-update — v0.5
- Figma layer export — post-1.0
