Deferred from the prior commits (both were co-edited with the concurrent actor at the time): README's stale crate list -> accurate op-* entry-crates table (matching the cargo:wasm-check fix), and the op-web-daemon Cargo.lock package entry (hunk-staged to exclude the concurrent op-web-sdk changes still in flight).

|
||
## Why OpenPencil
|
||
|
||
<table>
|
||
<tr>
|
||
<td width="50%">
|
||
|
||
### 🎨 Prompt → Canvas
|
||
|
||
Describe any UI in natural language. Watch it appear on the infinite canvas in real-time with streaming animation. Modify existing designs by selecting elements and chatting.
|
||
|
||
</td>
|
||
<td width="50%">
|
||
|
||
### 🤖 Concurrent Agent Teams
|
||
|
||
The orchestrator decomposes complex pages into spatial sub-tasks. Multiple AI agents work on different sections simultaneously — hero, features, footer — all streaming in parallel with per-member canvas indicators.
|
||
|
||
</td>
|
||
</tr>
|
||
<tr>
|
||
<td width="50%">
|
||
|
||
### 🧠 Multi-Model Intelligence
|
||
|
||
Automatically adapts to each model's capabilities. Claude gets full prompts with thinking; GPT-4o/Gemini disable thinking; smaller models (MiniMax, Qwen, Llama) get simplified prompts for reliable output.
|
||
|
||
</td>
|
||
<td width="50%">
|
||
|
||
### 🔌 MCP Server
|
||
|
||
One-click install into Claude Code, Codex, Gemini, OpenCode, Kiro, or Copilot CLIs. Design from your terminal — read, create, and modify `.op` files through any MCP-compatible agent.
|
||
|
||
</td>
|
||
</tr>
|
||
<tr>
|
||
<td width="50%">
|
||
|
||
### 🎨 Style Guides
|
||
|
||
Built-in style guide library with tag-based fuzzy matching. Apply visual styles (glassmorphism, brutalist, retro, etc.) to AI-generated designs. MCP tools for external agent access.
|
||
|
||
</td>
|
||
<td width="50%">
|
||
|
||
### 📦 Design-as-Code
|
||
|
||
`.op` files are JSON — human-readable, Git-friendly, diffable. Design variables generate CSS custom properties. Code export to React + Tailwind or HTML + CSS.
|
||
|

</tr>
|
||
<tr>
|
||
<td width="50%">
|
||
|
||
### 🖥️ Runs Everywhere
|
||
|
||
Web app + native desktop on macOS, Windows, and Linux via Electron. Auto-updates from GitHub Releases. `.op` file association — double-click to open.
|
||
|
||
</td>
|
||
<td width="50%">
|
||
|
||
### ⌨️ CLI — `op`
|
||
|
||
Control the design tool from your terminal. `op design`, `op insert` — batch design DSL, node manipulation. Pipe in from files or stdin. Works with desktop app or web server.
|
||
|
||

</tr>
|
||
<tr>
|
||
<td width="50%">
|
||
|
||
### 🎯 Multi-Platform Code Export
|
||
|
||
Export to React + Tailwind, HTML + CSS, Vue, Svelte, Flutter, SwiftUI, Jetpack Compose, React Native — all from one `.op` file. Design variables become CSS custom properties.
|
||
|
||
</td>
|
||
<td width="50%">
|
||
|
||
### 🧩 Embeddable SDK
|
||
|
||
`pen-engine` (headless) + `pen-react` (React UI SDK) — embed the design engine in your own app. DesignProvider, DesignCanvas, hooks, panels, and toolbar components out of the box.
|

### 🛡️ Design System Kit
|
||
|
||
Manage reusable UIKits with style switching and component composition. Import/export kits from `.pen` files. Built-in registry with MCP tools for external access.

||
**macOS (Homebrew):**
|
||
|
||
```bash
|
||
brew tap zseven-w/openpencil
|
||
brew install --cask openpencil
|
||
```
|
||
|
||
**Windows (Scoop):**
|
||
|
||
```powershell

```
|
||
|
||
**Linux / Windows direct download:** [GitHub Releases](https://github.com/ZSeven-W/openpencil/releases) — `.exe` (Windows), `.AppImage` / `.deb` (Linux)
|
||
|
||
**CLI (`op`):**
|
||
|
||
```bash
|
||
brew install zseven-w/openpencil/op
|
||
```
|
||
|
||
Or use the install script (macOS / Linux):
|
||
|
||
```bash
|
||
curl -fsSL https://raw.githubusercontent.com/ZSeven-W/openpencil/main/scripts/install-op.sh | bash
|
||
```
|
||
|
||
## Cloning(含 Rust 子系统)
|
||
|
||
```bash
|
||
git clone --recurse-submodules https://github.com/ZSeven-W/openpencil.git
|
||
# Or already cloned:
|
||
git submodule update --init --recursive
|
||
```
|
||
|
||
`vendor/agent` is the `agent-rs` submodule (cross-product, OP + Zode share); HTTPS URL needs no SSH key.
|
||
|
||
## Quick Start (Development)
|
||
|
||
```bash
|
||
# Install dependencies
|
||
bun install
|
||
|
||
# Start dev server at http://localhost:3000
|

|
||
Or run as a desktop app:
|
||
|
||
```bash
|
||
bun run electron:dev
|
||
```
|
||
|
||
> **Prerequisites:** [Bun](https://bun.sh/) >= 1.0 and [Node.js](https://nodejs.org/) >= 18. Optional: [Zig](https://ziglang.org/) >= 0.14 for building `agent-native` from source (a prebuilt binary will be downloaded automatically if Zig is not installed).
|
||
|
||
### Docker
|
||
|
||
Multiple image variants are available — pick the one that fits your needs:
|
||
|
||
| Image | Size | Includes |
|
||
| ---------------------------- | ------- | -------------------- |
|
||
| `openpencil:latest` | ~226 MB | Web app only |
|
||
| `openpencil-claude:latest` | — | + Claude Code CLI |
|
||
| `openpencil-codex:latest` | — | + Codex CLI |
|
||
| `openpencil-opencode:latest` | — | + OpenCode CLI |
|
||
| `openpencil-copilot:latest` | — | + GitHub Copilot CLI |
|
||
| `openpencil-gemini:latest` | — | + Gemini CLI |
|
||
| `openpencil-full:latest` | ~1 GB | All CLI tools |
|
||
|
||
**Run (web only):**
|
||
|
||
```bash
|
||
docker run -d -p 3000:3000 ghcr.io/zseven-w/openpencil:latest
|
||
```
|
||
|
||
**Run with AI CLI (e.g. Claude Code):**
|
||
|
||
The AI chat relies on Claude CLI OAuth login. Use a Docker volume to persist the login session:
|
||
|
||
```bash
|
||
# Step 1 — Login (one-time)
|
||
docker volume create openpencil-claude-auth
|
||
docker run -it --rm \
|
||
-v openpencil-claude-auth:/root/.claude \
|
||
ghcr.io/zseven-w/openpencil-claude:latest claude login
|
||
|
||
# Step 2 — Start
|
||
docker run -d -p 3000:3000 \
|
||
-v openpencil-claude-auth:/root/.claude \
|
||
ghcr.io/zseven-w/openpencil-claude:latest
|
||
```
|
||
|
||
**Build locally:**
|
||
|
||
```bash
|
||
# Base (web only)
|
||
docker build --target base -t openpencil .
|
||
|
||
# With a specific CLI
|
||
docker build --target with-claude -t openpencil-claude .
|
||
|
||
# Full (all CLIs)
|
||
docker build --target full -t openpencil-full .
|
||
```
|
||
|
||
## AI-Native Design
|
||
|
||
**Prompt to UI**
|
||
|
||
- **Text-to-design** — describe a page, get it generated on canvas in real-time with SSE streaming animation
|
||
- **Orchestrator** — decomposes complex pages into spatial sub-tasks for parallel generation
|
||
- **Agent Teams** — concurrent team members with delegate tool, per-member canvas indicators, and fallback strategies
|
||
- **Design modification** — select elements, then describe changes in natural language
|
||
- **Vision input** — attach screenshots or mockups for reference-based design
|
||
- **Style Guides** — apply visual styles (glassmorphism, brutalist, retro, etc.) via tag-based fuzzy matching
|
||
- **Anti-slop** — cross-generation diversity tracking to avoid repetitive AI output
|
||
|
||
**Multi-Agent Support**
|
||
|
||
| Agent | Setup |
|
||
| --------------------------- | ------------------------------------------------------------------------------------------------- |
|
||
| **Built-in (9+ providers)** | Select from provider presets with region switcher — Anthropic, OpenAI, Google, DeepSeek, and more |
|
||
| **Claude Code** | No config — uses Claude Agent SDK with local OAuth |
|
||
| **Codex CLI** | Connect in Agent Settings (`Cmd+,`) |
|
||
| **OpenCode** | Connect in Agent Settings (`Cmd+,`) |
|
||
| **GitHub Copilot** | `copilot login` then connect in Agent Settings (`Cmd+,`) |
|
||
| **Gemini CLI** | Connect in Agent Settings (`Cmd+,`) |
|
||
|
||
**Model Capability Profiles** — automatically adapts prompts, thinking mode, and timeouts per model tier. Full-tier models (Claude) get complete prompts; standard-tier (GPT-4o, Gemini, DeepSeek) disable thinking; basic-tier (MiniMax, Qwen, Llama, Mistral) get simplified nested-JSON prompts for maximum reliability.
|
||
|
||
**i18n** — Full interface localization in 15 languages: English, 简体中文, 繁體中文, 日本語, 한국어, Français, Español, Deutsch, Português, Русский, हिन्दी, Türkçe, ไทย, Tiếng Việt, Bahasa Indonesia.
|
||
|
||
**MCP Server**
|
||
|
||
- Built-in MCP server (`pen-mcp` package) — one-click install into Claude Code / Codex / Gemini / OpenCode / Kiro / Copilot CLIs
|
||
- Auto-detects Node.js — if not installed, falls back to HTTP transport and auto-starts the MCP HTTP server
|
||
- Design automation from terminal: read, create, and modify `.op` files via any MCP-compatible agent
|
||
- **Layered design workflow** — `design_skeleton` → `design_content` → `design_refine` for higher-fidelity multi-section designs
|
||
- **Segmented prompt retrieval** — load only the design knowledge you need (schema, layout, roles, icons, planning, etc.)
|
||
- **Style guide tools** — `get_style_guide_tags` and `get_style_guide` for applying visual styles via MCP
|
||
- Multi-page support — create, rename, reorder, and duplicate pages via MCP tools
|
||
|
||
**Code Generation**
|
||
|
||
- React + Tailwind CSS, HTML + CSS, CSS Variables
|
||
- Vue, Svelte, Flutter, SwiftUI, Jetpack Compose, React Native
|
||
|
||
## CLI — `op`
|
||
|
||
Install via Homebrew and control the design tool from your terminal:
|
||
|
||
```bash
|
||
brew install zseven-w/openpencil/op
|
||
```
|
||
|
||
```bash
|
||
op start # Launch desktop app
|
||
op design @landing.txt # Batch design from file
|
||
op insert '{"type":"RECT"}' # Insert a node
|
||
op import:figma design.fig # Import Figma file
|
||
cat design.dsl | op design - # Pipe from stdin
|
||
```
|
||
|
||
Supports three input methods: inline string, `@filepath` (read from file), or `-` (read from stdin). Works with desktop app or web dev server. See [CLI README](./apps/cli/README.md) for full command reference.
|
||
|
||
**LLM Skill** — install the [OpenPencil Skill](https://github.com/ZSeven-W/openpencil-skill) plugin to teach AI agents (Claude Code, Cursor, Codex, Gemini CLI, etc.) how to design with `op`.

## Why Rust
|
||
|
||
OpenPencil is being rewritten from the ground up in **Rust** ([#129](https://github.com/ZSeven-W/openpencil/issues/129)). The TypeScript + Electron build is what ships today; the Rust rewrite is what's next — one native core that is dramatically smaller and faster, and runs on more platforms from a single codebase.
|
||
|
||
| | TypeScript + Electron (today) | Rust (the rewrite) |
|
||
| --------------------- | ---------------------------------------------- | ------------------------------------------------------------------- |
|
||
| **Desktop runtime** | Electron — bundles Chromium + Node.js | Native window (`winit` + GPU Skia), no browser engine |
|
||
| **Desktop footprint** | Full Chromium runtime per install | Single self-contained binary — **55.5 MB** |
|
||
| **Web payload** | JS + WASM bundle | **8.2 MB** wasm / **2.18 MB** gzip over the wire |
|
||
| **Rendering** | CanvasKit/Skia on web | One GPU-accelerated Skia backend on **every** target |
|
||
| **Memory** | JavaScript GC pauses | No GC — Rust ownership, predictable latency |
|
||
| **Codebase** | Web stack + Electron + Zig NAPI agent | One Rust workspace: editor · CLI · MCP · AI · codegen · Figma · Git |
|
||
| **Targets** | Web + desktop, two separate stacks | Desktop (macOS/Win/Linux) · mobile (iOS/Android) · browser — one core |
|
||
|
||
**Measured improvements**
|
||
|
||
- **Tiny footprint** — the whole desktop app is one **55.5 MB** native binary instead of a bundled browser engine plus a Node runtime. The web build is **8.2 MB** raw / **2.18 MB** gzip after splitting the icon catalog (−48% over the wire).
|
||
- **Scales to large documents** — a **10,000-node** live canvas (nested auto-layout, four levels deep) writes, reads, and snapshots layout with **no panics and ~0% idle CPU**; a full layout snapshot of all 10k nodes returns in **~0.68 s**.
|
||
- **Fast interaction** — pan/zoom no longer re-serializes the document every frame (a single hot-path fix cut wheel-zoom CPU from **~69% to ~0%**); drags patch the scene incrementally, text measurement is cached, and repaints coalesce to one per frame.
|
||
- **One core, every screen** — the same editor state and the same render backend compile to native desktop, mobile, and the browser via WASM — no parallel reimplementations to keep in sync.
|
||
- **GPU Skia everywhere** — native renders through `skia-safe` on a GL context; the browser renders through CanvasKit on WebGL2 — the same drawing code, the same output.
|
||
- **Native accessibility** — AccessKit on macOS, Windows, and Linux, plus a DOM mirror on web, instead of leaning on a browser's a11y tree.
|
||
- **One type-checked workspace** — the MCP host, CLI, AI providers, code generation, Figma import, and Git integration all live in a single Rust workspace, with `cargo-deny` supply-chain gating in CI.
|
||
|
||
> **Status:** the Rust shell is under active development (see the Roadmap below). Until it reaches feature parity for `v0.8.0`, the installable downloads above are the TypeScript + Electron build.

### Rust subsystem (Step 0+)
|
||
|
||
OpenPencil 正在进行全量 Rust 化。当前状态见 `openpencil-docs/superpowers/specs/2026-05-02-rust-ification-kickoff.md`(v7 FROZEN)。
|
||
|
||
```bash
|
||
# Install Rust toolchain (rust-toolchain.toml auto-pins 1.94)
|
||
rustup toolchain install 1.94
|
||
rustup target add wasm32-unknown-unknown
|
||
|
||
# build / test / lint
|
||
bun run cargo:check
|
||
bun run cargo:test
|
||
bun run cargo:clippy
|
||
bun run cargo:wasm-check # kickoff §1.2 wasm32 invariant
|
||
bun run cargo:deny # cargo-deny (native + wasm32 bans; CI uses cargo-deny-action@v2)
|
||
```
|
||
|
||
**Entry crates (`crates/` — build targets):**
|
||
|
||
| Crate | Category | wasm32 |
|
||
| --------------- | -------------------------------------------------------------------------------- | ---------------- |
|
||
| op-host-web | Browser bundle entry — wasm32 cdylib, renders via CanvasKit | ✅ |
|
||
| op-host-native | Native host lib — WidgetHostNative + skia-safe GL backend (desktop + mobile) | ❌ (native only) |
|
||
| op-host-desktop | Desktop binary `openpencil-desktop` (winit + skia-safe GL) — also the `--serve-web` daemon that hosts the web bundle | ❌ (native only) |
|
||
| op-cli | `op` command-line tool | ❌ (native only) |
|
||
| op-app | Thin composition root — re-exports the per-platform host (target-gated) | ✅ / ❌ per target |
|
||
|
||
**Shared library crates:** `op-editor-core` (canonical `.op` state), `op-editor-ui` (platform-free widgets + `RenderBackend`), `op-editor-host-core` (transport-free host state machines), `op-mcp`, `op-ai`, `op-ai-skills`, `op-codegen`, `op-orchestrator`, `op-figma`, `op-git`, `op-opmerge`, `op-pen-loader`, `op-design-lint`, `op-config-store`, `op-process-io`, `op-acp`, `op-i18n`, `op-rpc-transport` — plus `op-smoke` (headless design-turn test runner). The browser bundle renders through the official CanvasKit skia WASM (loaded separately), so the retired `skia-safe-op` wasm fork + `wasm-libc-shim` no longer exist.
|
||
|
||
**Submodule:** `vendor/agent` → `github.com/ZSeven-W/agent-rs` (cross-product Rust agent runtime).
|
||
|
||
**Phase boundary:** Step 0 = workspace skeleton only (no feature porting). Real implementation begins at Step 1 (kill-spike) and beyond.

## Roadmap
|
||
|
||
- [x] Design variables & tokens with CSS sync
|
||
- [x] Component system (instances & overrides)
|
||
- [x] AI design generation with orchestrator
|
||
- [x] MCP server integration with layered design workflow
|
||
- [x] Multi-page support
|
||
- [x] Figma `.fig` import
|
||
- [x] Boolean operations (union, subtract, intersect)
|
||
- [x] Multi-model capability profiles
|
||
- [x] Monorepo restructure with reusable packages
|
||
- [x] CLI tool (`op`) for terminal control
|
||
- [x] Built-in AI agent SDK with multi-provider support
|
||
- [x] i18n — 15 languages
|
||
- [x] Headless design engine (`pen-engine`) + React UI SDK (`pen-react`)
|
||
- [x] Style Guides with tag-based matching and MCP tools
|
||
- [x] Concurrent Agent Teams with delegate tool and canvas indicators
|
||
- [x] Native agent runtime (`agent-native` — Zig NAPI)
|
||
- [x] Git integration — clone, branch, push/pull, folder-mode three-way merge
|
||
- [x] Canvas raster export (PNG / JPEG / WEBP / PDF)
|
||
- [x] Rust shell — Step 1a (G1 shared Skia context) on `v0.8.0`: `SharedSkiaContext` + `NativeBackend` (Jian-`DrawOp`-backed) + shell-core re-exports `jian_core::gesture::*` (events stay consistent with Jian — no OP-side translation layer per v19.4) + `basic_window` demo, with the multi-platform CI matrix green (macOS aarch64 + x86_64, Linux x86_64 + aarch64 cross, Windows x86_64 + aarch64 cross, iOS aarch64 + sim, Android aarch64 + x86_64, wasm32). Spec `v19.5` FROZEN; `vendor/jian` pinned at `c4a794dc`. OP visual model (single-page + infinite canvas canonical / multi-page also supported / no routing / Figma import auto-converts) and OP chrome (toolbars / panels — Rust-only) deferred to Step 1c+.
