Open Design

The open-source alternative to Claude Design. Local-first, web-deployable, BYOK at every layer — your existing coding agent (Claude Code, Codex, Cursor Agent, Gemini CLI, OpenCode, Qwen) becomes the design engine, driven by 19 composable Skills and 71 brand-grade Design Systems.

Why this exists

Anthropic's Claude Design (released 2026-04-17, Opus 4.7) showed what happens when an LLM stops writing prose and starts shipping design artifacts. It went viral — and stayed closed-source, paid-only, cloud-only, locked to Anthropic's model and Anthropic's skills. There is no checkout, no self-host, no Vercel deploy, no swap-in-your-own-agent.

Open Design (OD) is the open-source alternative. Same loop, same artifact-first mental model, none of the lock-in. We don't ship an agent — the strongest coding agents already live on your laptop. We wire them into a skill-driven design workflow that runs on pnpm dev, deploys to Vercel, and stays BYOK at every layer.

Type make me a magazine-style pitch deck for our seed round. The interactive question form pops up before the model improvises a single pixel. The agent picks one of five curated visual directions. A live TodoWrite plan streams into the UI. The daemon builds a real on-disk project folder with a seed template, layout library, and self-check checklist. The agent reads them — pre-flight enforced — runs a five-dimensional critique against its own output, and emits a single <artifact> that renders in a sandboxed iframe seconds later.

That's not "AI tries to design something". That's an AI that has been trained, by the prompt stack, to behave like a senior designer with a working filesystem, a deterministic palette library, and a checklist culture — exactly the bar Claude Design set, but open and yours.

OD stands on four open-source shoulders:

alchaincyf/huashu-design — the design-philosophy compass. Junior-Designer workflow, the 5-step brand-asset protocol, the anti-AI-slop checklist, the 5-dimensional self-critique, and the "5 schools × 20 design philosophies" idea behind our direction picker — all distilled into src/prompts/discovery.ts.
op7418/guizang-ppt-skill — the deck mode. Bundled verbatim under skills/guizang-ppt/ with original LICENSE preserved; magazine-style layouts, WebGL hero, P0/P1/P2 checklists.
OpenCoworkAI/open-codesign — the UX north star and our closest peer. The first open-source Claude-Design alternative. We borrow its streaming-artifact loop, its sandboxed-iframe preview pattern (vendored React 18 + Babel), its live agent panel (todos + tool calls + interruptible generation), and its five-format export list (HTML / PDF / PPTX / ZIP / Markdown). We deliberately diverge on form factor — they are a desktop Electron app bundling pi-ai; we are a web app + local daemon that delegates to your existing CLI.
multica-ai/multica — the daemon-and-runtime architecture. PATH-scan agent detection, the local daemon as the only privileged process, the agent-as-teammate worldview.

Demo

_{Entry view — pick a skill, pick a design system, type the brief. The same surface for prototypes, decks, mobile apps, dashboards, and editorial pages.}	_{Turn-1 discovery form — before the model writes a pixel, OD locks the brief: surface, audience, tone, brand context, scale. 30 seconds of radios beats 30 minutes of redirects.}
_{Direction picker — when the user has no brand, the agent emits a second form with 5 curated directions (Monocle / Modern Minimal / Tech Utility / Brutalist / Soft Warm). One radio click → a deterministic palette + font stack, no model freestyle.}	_{Live todo progress — the agent's plan streams as a live card. in_progress → completed updates land in real time. The user can redirect cheaply, mid-flight.}
_{Sandboxed preview — every <artifact> renders in a clean srcdoc iframe. Editable in place via the file workspace; downloadable as HTML, PDF, ZIP.}	_{71-system library — every product system shows its 4-color signature. Click for the full DESIGN.md, swatch grid, and live showcase.}
_{Deck mode (guizang-ppt) — the bundled guizang-ppt-skill drops in unchanged. Magazine layouts, WebGL hero backgrounds, single-file HTML output, PDF export.}	_{Mobile prototype — pixel-accurate iPhone 15 Pro chrome (Dynamic Island, status bar SVGs, home indicator). Multi-screen prototypes use the shared /frames/ assets so the agent never re-draws a phone.}

Skills

19 skills ship in the box. Each is a folder under skills/ following the Claude Code SKILL.md convention with an extended od: frontmatter (mode, platform, scenario, preview, design_system).

Showcase examples

The visually distinctive skills you'll most likely run first. Each ships a real example.html you can open straight from the repo to see exactly what the agent will produce — no auth, no setup.

_{dating-web · prototype Consumer dating / matchmaking dashboard — left rail nav, ticker bar, KPIs, 30-day mutual-matches chart, editorial typography.}	_{digital-eguide · template Two-spread digital e-guide — cover (title, author, TOC teaser) + lesson spread with pull-quote and step list. Creator / lifestyle tone.}
_{email-marketing · prototype Brand product-launch HTML email — masthead, hero image, headline lockup, CTA, specs grid. Centered single-column, table-fallback safe.}	_{gamified-app · prototype Three-frame gamified mobile-app prototype on a dark showcase stage — cover, today's quests with XP ribbons + level bar, quest detail.}
_{mobile-onboarding · prototype Three-frame mobile onboarding flow — splash, value-prop, sign-in. Status bar, swipe dots, primary CTA.}	_{motion-frames · prototype Single-frame motion-design hero with looping CSS animations — rotating type ring, animated globe, ticking timer. Hand-off ready for HyperFrames.}
_{social-carousel · prototype Three-card 1080×1080 social-media carousel — cinematic panels with display headlines that connect across the series, brand mark, loop affordance.}	_{sprite-animation · prototype Pixel / 8-bit animated explainer slide — full-bleed cream stage, animated pixel mascot, kinetic Japanese display type, looping CSS keyframes.}

Adding a skill takes one folder. Read docs/skills-protocol.md for the extended frontmatter, fork an existing skill, restart the daemon, it appears in the picker.

Six load-bearing ideas

1 · We don't ship an agent. Yours is good enough.

The daemon scans your PATH for claude, codex, cursor-agent, gemini, opencode, and qwen on startup. Whichever it finds becomes the design engine — driven via stdio, with one adapter per CLI. Inspired by multica and cc-switch. No CLI? Anthropic API · BYOK is the same pipeline minus the spawn.

2 · Skills are files, not plugins.

Following Claude Code's SKILL.md convention, each skill is SKILL.md + assets/ + references/. Drop a folder into skills/, restart the daemon, it appears in the picker. The bundled magazine-web-ppt is op7418/guizang-ppt-skill committed verbatim — original license preserved, attribution preserved.

3 · Design Systems are portable Markdown, not theme JSON.

The 9-section DESIGN.md schema from VoltAgent/awesome-design-md — color, typography, spacing, layout, components, motion, voice, brand, anti-patterns. Every artifact reads from the active system. Switch system → next render uses the new tokens. The dropdown ships with Linear, Stripe, Vercel, Airbnb, Tesla, Notion, Apple, Anthropic, Cursor, Supabase, Figma, Resend, Raycast, Lovable, Cohere, Mistral, ElevenLabs, X.AI, Spotify, Webflow, Sanity, PostHog, Sentry, MongoDB, ClickHouse, Cal, Replicate, Clay, Composio… — 71 in total.

4 · The interactive question form prevents 80% of redirects.

OD's prompt stack hard-codes a RULE 1: every fresh design brief begins with a <question-form id="discovery"> instead of code. Surface · audience · tone · brand context · scale · constraints. A long brief still leaves design decisions open — visual tone, color stance, scale — exactly the things the form locks down in 30 seconds. The cost of a wrong direction is one chat round, not one finished deck.

This is the Junior-Designer mode distilled from huashu-design: batch the questions up front, show something visible early (even a wireframe with grey blocks), let the user redirect cheaply. Combined with the brand-asset protocol (locate · download · grep hex · write brand-spec.md · vocalise), it's the single biggest reason output stops feeling like AI freestyle and starts feeling like a designer who paid attention before painting.

5 · The daemon makes the agent feel like it's on your laptop, because it is.

The daemon spawns the CLI with cwd set to the project's artifact folder under .od/projects/<id>/. The agent gets Read, Write, Bash, WebFetch — real tools against a real filesystem. It can Read the skill's assets/template.html, grep your CSS for hex values, write a brand-spec.md, drop generated images, and produce .pptx / .zip / .pdf files that show up in the file workspace as download chips when the turn ends. Sessions, conversations, messages, tabs persist in a local SQLite DB — pop the project open tomorrow and the agent's todo card is right where you left it.

6 · The prompt stack is the product.

What you compose at send time isn't "system + user". It's:

DISCOVERY directives  (turn-1 form, turn-2 brand branch, TodoWrite, 5-dim critique)
  + identity charter   (OFFICIAL_DESIGNER_PROMPT, anti-AI-slop, junior-pass)
  + active DESIGN.md   (71 systems available)
  + active SKILL.md    (19 skills available)
  + project metadata   (kind, fidelity, speakerNotes, animations, inspiration ids)
  + skill side files   (auto-injected pre-flight: read assets/template.html + references/*.md)
  + (deck kind, no skill seed) DECK_FRAMEWORK_DIRECTIVE   (nav / counter / scroll / print)

Every layer is composable. Every layer is a file you can edit. Read src/prompts/system.ts and src/prompts/discovery.ts to see the actual contract.

Quickstart

git clone https://github.com/nexu-io/open-design.git
cd open-design
pnpm install         # or npm install
pnpm dev:all         # daemon (:7456) + Vite (:5173)
open http://localhost:5173

The first load:

Detects which agent CLIs you have on PATH and picks one automatically.
Loads 19 skills + 71 design systems.
Pops the welcome dialog so you can paste an Anthropic key (only needed for the BYOK fallback path).
Auto-creates ./.od/ — the local runtime folder for the SQLite project DB, per-project artifacts, and saved renders. There is no od init step; the daemon mkdirs everything it needs on boot.

Type a prompt, hit Send, watch the question form arrive, fill it, watch the todo card stream, watch the artifact render. Click Save to disk or download as a project ZIP.

First-run state (`./.od/`)

The daemon owns one hidden folder at the repo root. Everything in it is gitignored and machine-local — never commit it.

.od/
├── app.sqlite                 ← projects · conversations · messages · open tabs
├── artifacts/                 ← one-off "Save to disk" renders (timestamped)
└── projects/<id>/             ← per-project working dir, also the agent's cwd

Want to…	Do this
Inspect what's in there	`ls -la .od && sqlite3 .od/app.sqlite '.tables'`
Reset to a clean slate	stop the daemon, `rm -rf .od`, run `pnpm dev:all` again
Move it elsewhere	not supported yet — the path is hard-coded relative to the repo

Visual directions

When the user has no brand spec, the agent emits a second form with five curated directions — the OD adaptation of huashu-design's "5 schools × 20 design philosophies" fallback. Each direction is a deterministic spec — palette in OKLch, font stack, layout posture cues, references — that the agent binds verbatim into the seed template's :root. One radio click → a fully specified visual system. No improvisation, no AI-slop.

Direction	Mood	Refs
Editorial — Monocle / FT	Print magazine, ink + cream + warm rust	Monocle · FT Weekend · NYT Magazine
Modern minimal — Linear / Vercel	Cool, structured, minimal accent	Linear · Vercel · Stripe
Tech utility	Information density, monospace, terminal	Bloomberg · Bauhaus tools
Brutalist	Raw, oversized type, no shadows, harsh accents	Bloomberg Businessweek · Achtung
Soft warm	Generous, low contrast, peachy neutrals	Notion marketing · Apple Health

Full spec → src/prompts/directions.ts.

Anti-AI-slop machinery

The whole machinery below is the huashu-design playbook, ported into OD's prompt-stack and made enforceable per-skill via the side-file pre-flight. Read src/prompts/discovery.ts for the live wording:

Question form first. Turn 1 is <question-form> only — no thinking, no tools, no narration. The user chooses defaults at radio speed.
Brand-spec extraction. When the user attaches a screenshot or URL, the agent runs a five-step protocol (locate · download · grep hex · codify brand-spec.md · vocalise) before writing CSS. Never guesses brand colors from memory.
Five-dim critique. Before emitting <artifact>, the agent silently scores its output 1–5 across philosophy / hierarchy / execution / specificity / restraint. Anything under 3/5 is a regression — fix and rescore. Two passes is normal.
P0/P1/P2 checklist. Every skill ships a references/checklist.md with hard P0 gates. The agent must pass P0 before emitting.
Slop blacklist. Aggressive purple gradients, generic emoji icons, rounded card with left-border accent, hand-drawn SVG humans, Inter as a display face, invented metrics — explicitly forbidden in the prompt.
Honest placeholders > fake stats. When the agent doesn't have a real number, it writes — or a labelled grey block, not "10× faster".

Supported coding agents

Auto-detected from PATH on daemon boot. No config required.

Agent	Bin	Streaming	Notes
Claude Code	`claude`	`--output-format stream-json` (typed events)	First-class — best fidelity
Codex CLI	`codex`	line-buffered	`codex exec <prompt>`
Cursor Agent	`cursor-agent`	line-buffered	`cursor-agent -p`
Gemini CLI	`gemini`	line-buffered	`gemini -p`
OpenCode	`opencode`	line-buffered	`opencode run`
Qwen Code	`qwen`	line-buffered	`qwen -p`
Anthropic API · BYOK	n/a	SSE direct	Browser fallback when no CLI is on PATH

Adding a new CLI is one entry in daemon/agents.js. Streaming format is one of claude-stream-json (typed events) or plain (raw text).

References & lineage

Every external project this repo borrows from. Each link goes to the source so you can verify the provenance.

Project	Role here
`Claude Design`	The closed-source product this repo is the open-source alternative to.
`alchaincyf/huashu-design`	The design-philosophy core. Junior-Designer workflow, the 5-step brand-asset protocol, anti-AI-slop checklist, 5-dimensional self-critique, and the "5 schools × 20 design philosophies" library behind our direction picker — all distilled into `src/prompts/discovery.ts` and `src/prompts/directions.ts`.
`op7418/guizang-ppt-skill`	Magazine-web-PPT skill bundled verbatim under `skills/guizang-ppt/` with original LICENSE preserved. Default for deck mode. P0/P1/P2 checklist culture borrowed for every other skill.
`multica-ai/multica`	The daemon + adapter architecture. PATH-scan agent detection, local daemon as the only privileged process, agent-as-teammate worldview. We adopt the model; we do not vendor the code.
`OpenCoworkAI/open-codesign`	The first open-source Claude-Design alternative and our closest peer. UX patterns adopted: streaming-artifact loop, sandboxed-iframe preview (vendored React 18 + Babel), live agent panel (todos + tool calls + interruptible), five-format export list (HTML/PDF/PPTX/ZIP/Markdown), local-first storage hub, `SKILL.md` taste-injection. UX patterns on our roadmap: comment-mode surgical edits, AI-emitted tweaks panel. We deliberately do not vendor `pi-ai` — open-codesign bundles it as the agent runtime; we delegate to whichever CLI the user already has.
`VoltAgent/awesome-claude-design` / `awesome-design-md`	Source of the 9-section `DESIGN.md` schema and 69 product systems imported via `scripts/sync-design-systems.mjs`.
`farion1231/cc-switch`	Inspiration for symlink-based skill distribution across multiple agent CLIs.
Claude Code skills	The `SKILL.md` convention adopted verbatim — any Claude Code skill drops into `skills/` and is picked up by the daemon.

Long-form provenance write-up — what we take from each, what we deliberately don't — lives at docs/references.md.

Roadmap

Daemon + agent detection + skill registry + design-system catalog
Web app + chat + question form + todo progress + sandboxed preview
19 skills + 71 design systems + 5 visual directions + 5 device frames
SQLite-backed projects · conversations · messages · tabs · templates
Comment-mode surgical edits (click element → instruction → patch) — pattern from open-codesign
AI-emitted tweaks panel (model surfaces the parameters worth tweaking) — pattern from open-codesign
Vercel + tunnel deployment recipe (Topology B)
One-command npx od init to scaffold a project with DESIGN.md
Skill marketplace (od skills install <github-repo>)

Phased delivery → docs/roadmap.md.

Status

This is an early implementation — the closed loop (detect → pick skill + design system → chat → parse <artifact> → preview → save) runs end-to-end. The prompt stack and skill library are where most of the value lives, and they're stable. The component-level UI is shipping daily.

Contributing

Issues, PRs, new skills, and new design systems are all welcome. The highest-leverage contributions are usually one folder, one Markdown file, or one PR-sized adapter:

Add a skill — drop a folder into skills/ following the SKILL.md convention.
Add a design system — drop a DESIGN.md into design-systems/<brand>/ using the 9-section schema.
Wire up a new coding-agent CLI — one entry in daemon/agents.js.
