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.

Quickstart

Time to first artifact: about 3 minutes

Requires: one API key, ChatGPT subscription sign-in, or local Ollama

Runs on: macOS 12+ (Monterey or later), Windows 10+, Linux (glibc ≥ 2.31)

1. Install

Package manager (recommended):

# macOS
brew install --cask opencoworkai/tap/open-codesign

# Windows — Scoop
scoop bucket add opencoworkai https://github.com/OpenCoworkAI/scoop-bucket
scoop install opencoworkai/open-codesign

Or direct download from the v0.2.0 GitHub Release:

| Platform | File | |---|---| | macOS (Apple Silicon) | open-codesign-*-arm64.dmg | | macOS (Intel) | open-codesign-*-x64.dmg | | Windows (x64) | open-codesign-*-x64-setup.exe | | Windows (ARM64) | open-codesign-*-arm64-setup.exe | | Linux (x64, AppImage) | open-codesign-*-x64.AppImage | | Linux (x64, Debian/Ubuntu) | open-codesign-*-x64.deb | | Linux (x64, Fedora/RHEL) | open-codesign-*-x64.rpm |

Each release ships with SHA256SUMS.txt and a CycloneDX SBOM (*-sbom.cdx.json) so you can verify what you downloaded.

<details> <summary><b>More package managers</b></summary>

| Manager | Command | Status | |---|---|---| | Homebrew Cask (macOS) | brew install --cask opencoworkai/tap/open-codesign | 🟢 Live | | Scoop (Windows) | scoop bucket add opencoworkai https://github.com/OpenCoworkAI/scoop-bucket && scoop install opencoworkai/open-codesign | 🟢 Live | | winget (Windows) | winget install OpenCoworkAI.OpenCoDesign | 🟡 PR submitted; waiting for Microsoft review | | Flathub (Linux) | flatpak install flathub ai.opencowork.codesign | ⏸ Deferred; needs signed build + AppStream metadata | | Snap (Linux) | snap install --dangerous open-codesign-*.snap | 🟡 Attached to releases best-effort; Snap Store publish not yet wired |

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.

2. Add a provider

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-...), Goog
