What is OpenDesign

OpenDesign is a collaborative design agent workspace. Start with a brief, then use your coding agent or OpenDesign Cloud to create a prototype that follows your design system. Share it with your team for feedback, and let your agent refine it in the same project.

That workflow is open and extensible. As the open-source Claude Design alternative, OpenDesign is licensed under Apache 2.0 and gives teams skills, design templates, design systems, and plugins they can inspect and adapt to their own process.

Platform Compatibility

OpenDesign connects to mainstream coding agents in two ways: skills, CLI, and MCP for agents that consume OD, plus native runtime adapters for agents that OD launches directly. DeepSeek Harness is a first-class native runtime through the official dsh CLI, with structured streaming, model discovery, cancellation, and session resume.

| Coding agent / platform          | Status    | Quick setup                    | |---|:---:|---| | Claude Code | ✅ Supported | od mcp install claude | | Claude Desktop | ✅ Supported¹ | od mcp install claude-desktop | | Codex CLI | ✅ Supported | od mcp install codex | | DeepSeek Reasonix | ✅ Supported | od mcp install reasonix | | DeepSeek Harness | ✅ Native runtime | od agent setup deepseek-harness | | Raven | ✅ Supported | od mcp install raven | | Cursor | ✅ Supported | od mcp install cursor | | VS Code + GitHub Copilot | ✅ Supported | od mcp install copilot | | GitHub Copilot CLI | ✅ Supported | od mcp install copilot | | OpenCode | ✅ Supported | od mcp install opencode | | OpenClaw | ✅ Supported | od mcp install openclaw | | Antigravity | ✅ Supported | od mcp install antigravity | | Cline | ✅ Supported | od mcp install cline | | Trae | ✅ Supported | od mcp install trae | | Kimi CLI | ✅ Supported | od mcp install kimi | | Kiro | ✅ Supported | od mcp install kiro | | Pi Agent | ✅ Supported | od mcp install pi | | Mistral Vibe CLI | ✅ Supported | od mcp install vibe | | Hermes Agent | ✅ Supported | od mcp install hermes |

For DeepSeek Harness, install the official dsh CLI first, then select it in OpenDesign or run od agent setup deepseek-harness to install/repair OD's connection component. For MCP integrations: od mcp install --print for a dry-run preview · --uninstall to remove · full list with od mcp install --help.

¹ Automatic MCP configuration for Claude Desktop is currently supported on macOS and Windows only.

No CLI installed? The BYOK proxy at POST /api/proxy/{anthropic,openai,azure,google,ollama,senseaudio}/stream gives you the same loop (no process spawn) — paste baseUrl + apiKey + model, with presets for OpenAI, Atlas Cloud, Anthropic, Azure OpenAI, Google Gemini, Ollama, LM Studio, vLLM, or any OpenAI-compatible endpoint. Atlas Cloud uses https://api.atlascloud.ai/v1 with your own key and OpenAI-compatible model ids such as qwen/qwen3.5-flash. Per-target SSRF protection blocks internal IPs / link-local / CGNAT at the daemon edge.

Runtime definitions live in apps/daemon/src/runtimes/defs/, with registration and shared stream handling under apps/daemon/src/runtimes/. See docs/agent-adapters.md for the adapter contract.

Demo

Four core product categories, all rendered by a coding agent running on your laptop. Click a thumbnail to see the real example.

1 · Prototypes — web · desktop · mobile

The default output surface. Single-page HTML artifacts that read your DESIGN.md and render in a sandboxed iframe.

Web prototype — an editorial dashboard with scrollbars, KPIs, and charts. Rendered straight from design-templates/dating-web/.

Mobile app prototype — a three-screen gamified flow with XP ribbons and quest detail. Hand off straight to Cursor / Codex / Claude Code to turn into React/Next/Vue.

2 · Live artifacts & dashboards

Live dashboards, decision rooms, KPI walls — single-page artifacts that pull data through a tweaks panel and stay editable in place.

Live dashboard — an editable KPI wall whose tweaks panel surfaces the parameters worth nudging. The agent emits a manifest, and the iframe re-renders without a reload.	Decision room — a multi-source briefing artifact for product / research / ops meetings.
GitHub-style dashboard — repo metrics presented as a live artifact.	Flow live-dashboard template — a domain-specific KPI template, branded through the active DESIGN.md.

3 · Decks — magazine decks, weekly updates, pitches

Deck mode (guizang-ppt) — magazine layouts, WebGL hero, P0/P1/P2 checklists. Bundled verbatim from op7418/guizang-ppt-skill with its original license preserved.

Swiss International-style deck — grid-anchored, monochrome accents. One of 15 deck templates and 36 themes under design-templates/html-ppt-*/.

Every deck exports to HTML (single file, inlined assets), PDF (browser print, deck-aware), PPTX (agent-driven skill), ZIP (archive), or Markdown.

4 · Images — gpt-image-2, ImageRouter, custom API

Illustrated city food map Hand-drawn editorial travel poster

Cinematic elevator scene Single-frame editorial still

Cyberpunk portrait Profile avatar — neon face text

3D stone staircase Hewn-stone infographic

Glamorous portrait Editorial studio shot

93 ready-to-replicate prompts live in prompt-templates/ — preview thumbnails, full prompt body, target model, aspect ratio, and source attribution. One click drops a brief into the composer.

5 · Video & HyperFrames — agent-native motion graphics

[HyperFrames][hyperframes] is HeyGen's open-source, agent-native video framework, integrated as a first-class citizen in OpenDesign. The agent writes HTML + CSS + GSAP, and HyperFrames renders it to a deterministic MP4 via headless Chrome + FFmpeg. Pair it with Seedance 2.0 for cinematic t2v / i2v, Veo 3 / Sora 2 / Kling 2 for routed model variants, and Suno v5 / Lyria 2 for the audio layer.

30s SaaS product promo · 16:9 · UI 3D reveals	TikTok karaoke talking-head · 9:16 · TTS + word-synced captions	30s brand sizzle reel · 16:9 · audio-reactive kinetic type	Bar chart race · 16:9 · NYT-style data infographic
Flight map · 16:9 · Apple-style route reveal	4s cinematic logo outro · 16:9 · piece-by-piece assembly + bloom	$0 → $10K money counter · 9:16 · Apple-style hype	Website-to-video · 16:9 · captures the site at 3 viewports

11 HyperFrames templates + 39 Seedance prompts ship with the repo. Catalog thumbnails © HeyGen; the framework is Apache-2.0. The OD-specific render workflow (composition cache, sandbox-exec workaround, MP4-as-chip) is detailed in design-templates/hyperframes/.

Why OpenDesign

In April 2026, Anthropic released Claude Design — the first time an LLM stopped writing prose and started delivering design artifacts directly. It went viral. But it stayed closed-source, paid-only, cloud-only, locked to Anthropic's model, Anthropic's skills, Anthropic's surface. No checkout, no self-host, no Vercel deploy, no swap-in-your-own-agent.

OpenDesign (OD) is the open-source alternative. Same loop, same artifact-first mental model, none of the lock-in:

• 🤖 Agent-native, model-agnostic. We don't ship an agent. The claude / codex / cursor-agent / copilot / hermes / kimi already on your PATH are the design engine. Swap with one click.
• 🧠 Brand-grade by default. Every render reads the active package's DESIGN.md as the core brand contract. 151 design-system packages ship with the repo; legacy packages may be DESIGN.md-only, while newer packages can add manifest.json, tokens.css, components, assets, and provenance. Drop a folder in, the picker finds it.
• 🖥️ Local-first, BYOK at every layer. Native desktop apps for macOS (Apple Silicon + Intel) and Windows (x64). Linux desktop users can currently run OpenDesign from source; the latest official release does not include a prebuilt Linux artifact. Product analytics and session replay are consent-gated; scrubbed safety and reliability telemetry is always on. Before describing daemon data paths, contributors and operators MUST read AGENTS.md → Daemon data directory contract. This README MUST NOT restate it.
• 🌍 Composable on four planes. Plugins carry runnable workflows · functional skills carry agent behavior · design templates carry rendering blueprints · design systems carry the brand. All four use portable, versionable directories that anyone can author and publish.
• 🔁 Refresh an existing codebase. Hand a git repo + DESIGN.md to the agent and it refactors your real components to the brand spec. Dedicated plugins migrate Figma / Pencil workflows into React / Next.js / Vue code.
• 🔒 Privacy by conviction. Everything runs where your data lives — your laptop, your team's server, your Vercel project. When the network is needed, the BYOK proxy is SSRF-guarded.

Quick start

🖥️ Download the desktop app (recommended — zero config)

The fastest way to use OpenDesign. No Node, no pnpm, no clone.

• macOS (Apple Silicon · Intel x64) → open-design.ai or GitHub Releases
• Windows (x64) → open-design.ai or GitHub Releases
• Linux → No prebuilt Linux artifact is currently published in the official releases. For now, run OpenDesign from source; Linux release work is tracked in #4368.

After install: the app auto-detects every coding-agent CLI on your PATH, loads 100+ functional skills, the separate rendering-template catalog, and 151 design systems, and lets you type a brief in the entry view.

🤖 Install into your coding agent (no UI)

You can use OpenDesign without ever opening the GUI — call it as a skill, plugin, or MCP server inside Claude Code, Codex, Cursor, Copilot, OpenClaw, Antigravity, Hermes, Kimi, and more.

If you installed the macOS desktop app via the DMG or Homebrew cask, your shell may still resolve od to Apple's built-in /usr/bin/od octal-dump utility. In that case, open Settings → MCP server in the desktop app and copy the client-specific snippet; it uses absolute paths and does not rely on the bare od command.

# One-line install into the agent you're using:
od mcp install 
= claude | codex | reasonix | raven | cursor | copilot | openclaw
| antigravity | pi | vibe | hermes | cline | kimi | kiro
| trae | opencode
Hosted equivalent for curl-based setup:
curl -fsSL https://open-design.ai/install.sh | sh -s 

install.sh is a thin shell wrapper around od mcp install; it exists so the hosted URL returns shell instead of the landing-page HTML fallback and fails fast if your shell resolves a non-Open-Design od binary.

macOS / WSL2 users: /usr/bin/od is a system octal-dump command and can

shadow OpenDesign's od command. Desktop-app users should prefer the

Settings → MCP server snippet; WSL2 users should follow the

WSL2 setup guide first.
