The items in this section are the latest workflow upgrades added on top of the core Open CoDesign experience, so they stay separate from the baseline repo feature list below.
- Pinned
Canvastab with full Excalidraw UI — sketch wireframes, widgets, motion notes, and layout ideas directly in the app before the first generation - Canvas-to-model context export — the canvas is packaged into prompt context automatically as a summary plus PNG/SVG exports, with frame-aware exports when frames are present
- Imported canvas images are sent separately too — reference images dropped into the canvas also show up as standalone chat attachments for clearer model context
- Visible send confirmation — the composer and chat now show when canvas context was actually included, so you can confirm it at a glance
- Canvas autosave and save-on-submit — rough sketches are persisted per design, with an extra flush when you send a prompt
- Smart follow-up reuse — canvas context is only resent on later turns when the canvas changed since the last successful generation
For implementation details, see apps/desktop/CANVAS_CONTEXT.md.
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:
- 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.

Direct download (v0.1.x) from GitHub Releases:
| 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 |

Each release ships with SHA256SUMS.txt and a CycloneDX SBOM (*-sbom.cdx.json) so you can verify what you downloaded.
Package managers — status for v0.1.x

🟡 Attached to releases best-effort; Snap Store publish not yet wired |
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:
- Anthropic (
sk-ant-…) - OpenAI (
sk-…) - Google Gemini
- Any OpenAI-compatible relay (OpenRouter, SiliconFlow, local Ollama)
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, 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.
By default, the built-in taste layer stays on, and you can now toggle the stronger style modules in Settings → Advanced. That includes the original anti-slop layer plus an optional Uncodixfy-inspired cleanup skill for pushing layouts away from generic AI-looking tropes.
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 from Claude Code and Codex configs — bring your existing providers, models, and keys in a single click
- 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-generated sliders — the model emits the parameters worth tweaking (color, spacing, font)
- Paste screenshots into chat — paste an image straight into the prompt box and it becomes a normal attachment for the next generation
- 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
- Resilient preview fallback — if a generated artifact is malformed, the last good render stays visible instead of being replaced by a blank or broken canvas whenever possible
- Connection diagnostic panel — one-click test for any provider, with actionable errors
- Top-bar usage badge — see context-window usage, token totals, and USD cost for the latest run beside the model selector
- Automatic checklist continuation — unfinished agent todo lists can continue automatically with one silent follow-up; disable it anytime in Advanced settings
- Visual self-review — after the first render, Open CoDesign can capture the live preview as an image and feed it back into the same agent for one screenshot-based refinement pass
- Review prompts get the latest preview screenshot — prompts like "review", "what changed", or "does this look right?" can attach the last rendered UI as an image so the same agent can inspect the current result directly
- Toggleable taste controls — enable or disable visual self-review, the anti-slop skill, and the Uncodixfy-inspired cleanup skill in Advanced settings
- Binary image attachments stay binary — image-style attachments now use a larger size cap and are passed by filename/image context instead of being treated like text excerpts
- Settings with five tabs — Models, Appearance, Storage, Diagnostics, 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
We're on v0.1.3 — shipping fast, priorities can shift. This is what's on the bench right now.
- Provider & API config polish — smoother one-click import, model picker reaching the last gaps (custom providers, timeouts), clearer connection diagnostics
- Structured logging + issue-report bundle — better logs in the main/renderer processes and a one-click diagnostics export that makes bug reports actionable
- Filesystem support — read/write real project directories, not just in-app scratch space
- Broader import paths — bring existing assets, prompts, and project context into a design session
- 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
