OpenDesign: The open-source Claude Design alternative
⚡ OpenDesign Cloud — the official model service. One recharge to use both agent and image models inside OpenDesign: GPT, Claude, and DeepSeek for agents; GPT Image 2.0, Seedream 5.0 Pro, and Nano Banana 2.0 for images.
🚀 DeepSeek V4 Flash and V4 Pro are now available. Put top-tier intelligence to work across prototypes, decks, design systems, and everyday agent tasks. OpenDesign members can use both models without limits for two weeks, directly inside the app.
🧩 DeepSeek Harness is now supported. Connect DeepSeek's official
dshagent harness to OpenDesign as a native runtime, with structured thinking, tool calls, model discovery, cancellation, and session resume. Generated files stay in the OpenDesign workflow for live preview and delivery.

What is OpenDesign
🎨 The open-source Claude Design alternative. 🖥️ Local-first native desktop app for macOS and Windows. ⚡ Composable skills, brand-grade DESIGN.md design systems, and ready-to-use plugins. 🖼️ Generates web · desktop · mobile prototypes, live dashboards / artifacts, decks, images, video, plus HyperFrames motion graphics. 🔒 Sandboxed iframe preview · HTML / PDF / PPTX / MP4 export. 🤖 Runs on DeepSeek Harness (dsh) · Claude Code · OpenClaw · Codex · Cursor · OpenCode · Qwen · Copilot · Amp · Hermes · Kimi · Antigravity and 26 distinct local CLI executables, or any OpenAI-compatible endpoint via BYOK.
OpenDesign is what you get when the agent-native loop Anthropic shipped with Claude Design — discover the brief, lock the direction, stream the artifact, critique, deliver — stops being closed and becomes a filesystem of functional skills, rendering design templates, design systems, and plugins that the coding agents already on your laptop can read, write, and remix. Your CLI becomes the design engine, your laptop becomes the studio, and your team's DESIGN.md becomes the brand contract.
It's also the Figma alternative for the agent era — instead of pushing pixels on a canvas, it delivers single-page artifacts in real CSS, real fonts, real components, exported straight to HTML / PDF / PPTX / MP4 — already shaped by your design system, already runnable inside the agent you use every day.
Product tour
A quick look at the core OpenDesign workflow. Start from Home with a brief, explore reusable skills in Plugins, and turn brand references into a Design System. Then enter a project's Studio to create and refine prototypes, decks, mobile apps, images, documents, and HyperFrames in one place.
Core pages
 Home — choose an artifact type, enter a brief, and set the design system, working directory, and model before you start. |
 Plugins — browse official skills by category, search the catalog, and launch a workflow with Try it.
|
 Design System — extract and refine a brand's visual language, preview the result, and create with it in the same workspace. |
Studio — many artifact types in one project
Inside a project's Studio, the conversation, generated files, and live preview stay together across six artifact types:
 Prototype — generate or reconstruct web experiences, inspect the rendered page, and iterate with the agent in place. |
 Deck — create multi-slide presentations, review thumbnails and speaker notes, and export when ready. |
 Mobile app — generate and polish mobile interfaces in a device preview, with the conversation, output files, and next-step actions beside it. |
 Image — generate visual assets from the project conversation, preview the result at full size, then download or open it. |
 Document — create polished, multi-page guides and editorial documents, inspect the rendered layout, and export or share when ready. |
 HyperFrame — build code-driven motion graphics, preview the animation inside Studio, and export the finished video. |
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
dshCLI, with structured streaming, model discovery, cancellation, and session resume.

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 <agent> --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 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.

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/kimialready on yourPATHare the design engine. Swap with one click. - 🧠 Brand-grade by default. Every render reads the active package's
DESIGN.mdas the core brand contract. 151 design-system packages ship with the repo; legacy packages may beDESIGN.md-only, while newer packages can addmanifest.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 AppImage on the optional release lane. 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
gitrepo +DESIGN.mdto 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 (AppImage, optional lane) → GitHub Releases
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 <agent>
# <agent> = 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 <agent>
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/odis a system octal-dump command and can shadow OpenDesign'sodcommand. Desktop-app users should prefer the Settings → MCP server snippet; WSL2 users should follow theWSL2 setup guidefirst.
Then, inside the agent:
> Use open-design to generate a landing page with the Linear design system
In a filesystem-backed local CLI run, the agent composes the selected functional skill or design template with your DESIGN.md, writes the canonical project files, and OpenDesign previews those files. A BYOK/plain-API run without filesystem tools instead returns one complete <artifact> block.
🐳 Run with Docker
git clone https://github.com/nexu-io/open-design.git
cd open-design/deploy
cp .env.example .env
echo "OD_API_TOKEN=$(openssl rand -hex 32)" >> .env
docker compose up -d
# open http://127.0.0.1:7456
If the browser asks for credentials, use open-design as the username and the
OD_API_TOKEN value from deploy/.env as the password. This keeps Docker bridge
traffic authenticated without requiring host networking. API clients can keep
using Authorization: Bearer <OD_API_TOKEN>.
🚀 Deploy on Sealos
The Sealos App Store template runs the published OpenDesign Docker image with persistent workspace storage and Basic Auth on the public proxy. For custom public or shared Docker deployments, follow the reverse-proxy and OPEN_DESIGN_ALLOWED_ORIGINS guidance in deploy/README.md.
🧑💻 Run from source
git clone https://github.com/nexu-io/open-design.git
cd open-design
corepack enable && pnpm install
pnpm tools-dev run web
Open the URL printed by tools-dev; development ports are allocated dynamically unless you pass explicit port flags.
Node ~24, pnpm 10.33.x. WSL2 users, see docs/wsl-setup.md; native Windows users, see docs/windows-troubleshooting.md. Full quickstart, env vars, Nix flake, and packaged build flow → QUICKSTART.md.
A full workflow — from brief to artifact
brief → plugin → direction → design system → artifact → handoff → memory
- A PM submits a brief. The plugin picker offers landing page · pitch deck · dashboard · social post · PM spec · OKR scorecard…
- A designer (or the agent) locks the direction. No brand? Pick from 5 curated directions. Have a brand? Drop a screenshot / URL → the agent connects GitHub, imports Figma, and codifies a reusable
DESIGN.md. - The agent creates the first deliverable. Plugin + functional skill or design template +
DESIGN.mdare bound. Filesystem-backed CLI runs write canonical project files and the preview follows them; BYOK/plain-API runs without file tools return one complete<artifact>block. - Hand off to engineering. The artifact is real HTML/CSS — drop it into Cursor, Codex, or Claude Code to keep building as code. Or export PPTX / PDF / MP4 straight to marketing.
- OpenDesign gets smarter as you use it. Your screenshots, fonts, palettes, and confirmed artifacts accumulate as defaults for the next session. Less rework, less drift.
Use OpenDesign from your coding agent
OpenDesign ships a stdio MCP server and per-agent install scripts. Any MCP-compatible agent in another repo can read files from your local OpenDesign projects directly — tokens CSS, JSX components, entry HTML — as a structured API queryable by name. The agent always sees the live file, not a stale export.
# One-line install (16+ CLIs supported):
od mcp install <agent>
# Then the agent can:
od project list --json
od files list <project-id> --json
od files read <project-id> <relative-path>
od plugin list --json
od skills list --json
Why MCP? Exporting and re-attaching a zip every iteration breaks flow. MCP exposes the design source directly — the agent always sees the live file.
For an agent starting from scratch, the installer places ~/.config/<agent>/open-design.json (or the platform equivalent) plus a copy-paste MCP snippet. Cursor gets a one-click deeplink; Claude Code gets a claude mcp add-json one-liner; every other agent gets JSON in the schema its config expects. On macOS desktop installs, prefer that Settings snippet over typing bare od mcp install <agent> in Terminal, because /usr/bin/od may win on PATH. Full per-agent flow → Settings → MCP server in the desktop app, or docs/agent-adapters.md.
Security model. Read-only by default, the daemon binds to 127.0.0.1, and SSRF is blocked at the proxy edge. LAN exposure requires an explicit OD_BIND_HOST plus OD_ALLOWED_ORIGINS. Connector credentials and live-artifact preview routes stay loopback-only regardless.
Internally-hosted model endpoints. To prevent SSRF, the daemon blocks provider base URLs that resolve to private/internal address ranges (RFC1918, link-local, CGNAT, and cloud-metadata IPs) by default, surfacing Internal IPs blocked. If you run an internally-hosted gateway (e.g. LiteLLM or Ollama on a VPN-only 10.x/192.168.x address), opt that host out with OD_ALLOWED_INTERNAL_HOSTS=<host1>,<host2>,... — a comma- or whitespace-separated list of bare hostnames or IPs (10.0.0.5, litellm.internal.corp; a host:port or full URL is accepted and reduced to its hostname; IPv6 must be bracketed, e.g. [fd00::1]). The allowlist is strict opt-in (empty by default), exact-host (no subdomain/substring matching), and applies only to provider endpoints you configure (connection test, model discovery, BYOK chat). It deliberately does not relax the guard on download URLs returned inside upstream responses, which stay blocked. A malformed entry — or CIDR notation, which is not supported — is dropped with a warning rather than silently trusted, so a typo never quietly widens (or fails to widen) the guard. Allowlisting a hostname trusts whatever it resolves to (like OD_ALLOWED_ORIGINS); allowlist the resolved IP instead if you want the DNS-resolved address re-checked.
Skills and design templates
100+ functional skills ship in skills/. Each follows the Agent Skills SKILL.md convention and supplies reusable agent behavior, references, or utilities. Renderable starters live separately in design-templates/; they may also use SKILL.md, but they populate the design-template catalog rather than the functional-skill registry.
Two modes anchor the design-template catalog: prototype (web/mobile/desktop single-page artifacts) and deck (horizontal-swipe presentations). Other templates cover image, video, audio, and utility surfaces. The scenario field groups templates by audience: design · marketing · operation · engineering · product · finance · hr · sale · personal.

Design Systems
151 brand-grade design-system packages centered on DESIGN.md ship with the repo. Legacy packages may contain only that Markdown contract; newer packages can also carry manifest.json, compiled tokens.css, component fixtures, assets, and provenance evidence. The catalog mixes upstream-derived systems with project-owned additions; design-systems/README.md records the package shape and provenance. Switch a system → the next render uses the new tokens.

What plugins can do
- 🤖 Run in any coding agent — Claude Code, Codex, Cursor, Copilot, OpenClaw, Antigravity, Hermes, Kimi… through the same skill protocol the agent already knows.
- 🔁 Migrate Figma / Pencil workflows → React, Next.js, or Vue source. See
od-figma-migration. - 🛠️ Refresh an existing codebase to a brand spec — point a plugin at a
gitrepo +DESIGN.md, get a PR. Seeod-code-migration. - 💾 Persist custom workflows — your team's reusable templates sit next to the shipped ones.
Using plugins
Plugins are at full parity across the web UI and the od CLI — same /api/plugins endpoints, pick whichever fits.
In the desktop / web app: open the Plugin page to browse the marketplace and click Install; inside a project's Studio, plugins appear as composer chips you click to apply (with the inputs they declare).
On the command line (runs without a UI — this is the path external agents use):
od plugin list # list installed plugins (--task-kind / --mode / --tag filters)
od plugin search "landing page" # search by keyword
od plugin info od-default # inspect a plugin's metadata, inputs, capabilities
od plugin install od-figma-migration # install from a registry; also accepts ./local-folder or an https://… link
od plugin apply od-default --input brief="a one-page pitch for our seed round"
od plugin upgrade od-default # upgrade
od plugin uninstall od-default # uninstall
Every command supports --json, so you can pipe it through jq / xargs into automation.
Building a plugin
An OpenDesign plugin requires open-design.json plus the payload required by its type. A workflow skill or scenario also includes SKILL.md; manifest-only template and design-system entries use their own payloads instead:
my-plugin/
├── open-design.json ← required: marketplace metadata + inputs + pipeline + capabilities
├── SKILL.md ← required for agent-skill/scenario entries; omitted for other plugin types
├── README.md ← optional: usage, install, registry links
├── preview/ ← optional: index.html / poster.png (strongly recommended for visual plugins)
└── examples/ ← optional: concrete use cases
Core open-design.json fields: specVersion (currently 1.0.0), name (stable ID), version (semver), optional compat.agentSkills[].path (points at ./SKILL.md when the entry exposes an Agent Skill), od.kind (skill / scenario / atom / bundle), od.taskKind (new-generation / figma-migration / code-migration / tune-collab), od.mode (the output surface, e.g. prototype / deck / live-artifact / image / video / hyperframes / audio / design-system / scenario), od.capabilities[] (declare the minimum — a restricted install grants only prompt:inject by default), od.inputs[] (apply-time parameters).
Scaffold + validate locally:
od plugin scaffold --id my-plugin --title "My Plugin" # generate the skeleton
od plugin validate ./my-plugin # check manifest / file layout
pnpm guard && pnpm --filter @open-design/plugin-runtime typecheck

| Preview | Filesystem runs render canonical project files; BYOK/plain-API runs parse one complete <artifact> block into a sandboxed srcdoc iframe |
| Export | HTML (inlined) · PDF (browser print) · PPTX (agent-driven) · ZIP · Markdown · MP4 (HyperFrames) |
| Desktop | Electron shell + sandboxed renderer + sidecar IPC (STATUS · EVAL · SCREENSHOT · CONSOLE · CLICK · SHUTDOWN) |
| Lifecycle | One entry point: pnpm tools-dev (start / stop / run / status / logs / inspect / check) |

Roadmap
- Daemon + 27 runtime definitions across 26 distinct coding-agent CLI executables + skill/design-template registries + design-system catalog
- Web app + chat + question form + 5-direction picker + todo progress + sandboxed preview
- 100+ functional skills · separate rendering-template catalog · 151 design-system packages · 5 visual directions · 5 device frames
- SQLite-backed projects · conversations · messages · tabs · templates
- Multi-provider BYOK proxy (
/api/proxy/{anthropic,openai,azure,google,ollama,senseaudio}/stream) with OpenAI-compatible presets including Atlas Cloud + SSRF guard - Claude Design ZIP import (
/api/import/claude-design) - Sidecar protocol + Electron desktop + IPC automation
- Artifact lint API + 5-dim self-critique pre-emit gate
- 0.8.0 — plugin marketplace infrastructure (261 official plugins, manifest spec, per-agent install scripts)
- 0.9.0 — OpenDesign Cloud (official model service built into the app: zero config, one-click sign-in)
- 0.10.0 — the all-in-one design workspace: the whole craft loop in one window (references → material → interactive editing → motion → handoff)
- 0.11.0 — The Bazaar: built in the open — a community marketplace of plugins and design systems anyone can pick from and contribute to
- 0.12.0 — Brand-backed Design System: turn the brand you already own into a reusable, portable
DESIGN.mdsystem - 0.13.0 — Stay in Flow: native session resume, faster model picking, and export straight to screenshot-backed PPTX / PDF
- Packaged Electron builds — macOS (Apple Silicon + Intel) + Windows (x64) + Linux AppImage (optional lane)
- Comment-mode surgical edits — partially shipped; reliable targeted patching in progress
- AI-emitted tweaks panel UX — not yet implemented
-

Contributing
OpenDesign keeps moving because contributors — designers, engineers, prompt authors — keep showing up. Many of the most-used skills, design systems, and plugins were written by people outside the core team.
🎯 Where to start (max leverage, min change)
| Want to ship… | How | Where |
|---|---|---|
| A new functional skill | Drop a folder with SKILL.md + optional assets/ + references/ |
skills/ · spec in docs/skills-protocol.md |
| A new rendering design template | Add a renderable SKILL.md bundle |
design-templates/ |
| A new design system | Drop a package centered on DESIGN.md; add manifest.json, tokens.css, components, assets, or provenance when needed |
design-systems/<brand>/ |
| A new plugin | Drop open-design.json + the type-specific payload under a category folder |
plugins/community/ · spec in plugins/spec/SPEC.md · agent dev guide in plugins/spec/AGENT-DEVELOPMENT.md |
| Support a new coding-agent CLI | One runtime definition + registry entry; add a parser only for a new wire format | apps/daemon/src/runtimes/defs/ |
| Fix a bug or polish UI | Browse the good-first-issue label |

pnpm tools-dev run web
# 2. Find a good-first-issue and assign yourself
gh issue list --label "good first issue" --state open --limit 20
gh issue develop <number> # create a branch and worktree
# 3. Make the change, run the checks
pnpm guard && pnpm typecheck
pnpm --filter @open-design/<package> test
# 4. Open the PR
gh pr create --fill

🏅 OpenDesign Fellow program
We're recruiting OpenDesign Fellows around the world — Fellows shape the product alongside the core team, represent OpenDesign officially in their region, and grow the community locally, backed by funded support ($1,000 / MR), free LLM credits, and a direct review track. Details → MAINTAINERS.md and the announcement on Discord.
Maintainers
They carry a lot of the load — daily maintenance, review, and community support.
 @Nagendhra-web Maintainer |
 @Sid-Qin Maintainer |
 @YOMXXX Maintainer |
Maintainer rules, promotion criteria, and the exit protocol → MAINTAINERS.md (also Deutsch · Français · 简体中文 · 日本語 · 한국어 · Português · ภาษาไทย).
Contributors
Thanks to everyone who has taken part — code, docs, feedback, a sharp issue, a new skill, a new design system.
Repository activity
The SVG above is regenerated daily by .github/workflows/metrics.yml using lowlighter/metrics.
Star us
If this saved you thirty minutes, give it a ★. Stars don't pay rent — but they tell the next designer, agent, and contributor that this experiment is worth their attention. One click, three seconds, a real signal.
