Note: There is another open-source project with the same name — OpenPencil, focused on Figma-compatible visual design with real-time collaboration. This project focuses on AI-native design-to-code workflows.
Why OpenPencil
🎨 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.
🤖 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.
🧠 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.
🔌 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.
🎨 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.
📦 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.
🖥️ Runs Everywhere
Web app + native desktop on macOS, Windows, and Linux — one Rust core, a single self-contained binary, no browser engine. .op file association — double-click to open.
⌨️ 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.
🎯 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.
🧩 Embeddable SDK
op-web-sdk (vanilla) + op-web-sdk-react / op-web-sdk-vue adapters — embed a read-only .op viewer in your own app, powered by the same wasm renderer the editor ships.
🛡️ 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.
Install
macOS (Homebrew):
brew tap zseven-w/openpencil
brew install --cask openpencil
Windows (Scoop):
scoop bucket add openpencil https://github.com/zseven-w/scoop-openpencil
scoop install openpencil
Linux / Windows direct download: GitHub Releases — .exe (Windows), .AppImage / .deb (Linux)
CLI (op):
brew install zseven-w/openpencil/op
Or use the install script (macOS / Linux):
curl -fsSL https://raw.githubusercontent.com/ZSeven-W/openpencil/main/scripts/install-op.sh | bash
To allow the newest pre-release:
curl -fsSL https://raw.githubusercontent.com/ZSeven-W/openpencil/main/scripts/install-op.sh | OP_PRERELEASE=1 bash
Windows PowerShell:
irm https://raw.githubusercontent.com/ZSeven-W/openpencil/main/scripts/install-op.ps1 | iex
To allow the newest pre-release:
$env:OP_PRERELEASE = "1"; irm https://raw.githubusercontent.com/ZSeven-W/openpencil/main/scripts/install-op.ps1 | iex
Cloning (with submodules)
git clone --recurse-submodules https://github.com/ZSeven-W/openpencil.git
# Or already cloned — sync first so stale submodule URLs pick up .gitmodules changes:
git submodule sync --recursive && git submodule update --init --recursive
Three submodules live under vendor/, all public and fetched over HTTPS (no SSH key needed): jian (GPU-Skia UI framework — widgets/render/events), casement (winit fork), and agent (agent-rs — cross-product Rust agent runtime, shared by OP + Zode). vendor/anthropic-agent-sdk is tracked in-tree, not a submodule.
Quick Start (Development)
# Web dev server (builds the CanvasKit wasm bundle, then runs the headless web host)
bash scripts/start-web-rust.sh
Browser-entered built-in provider, image-generation, and Openverse credentials
are kept in same-origin localStorage
(openpencil-rust-web-credentials) by default,
separate from ordinary web preferences. A credential needed by an AI request is
sent with that request, but the daemon does not write the browser snapshot to
settings.json.
Private deployments can opt into server persistence with
OPENPENCIL_PERSIST_WEB_CREDENTIALS_SERVER=true. This setting is
deployment-wide; each accepted browser snapshot replaces the shared
browser-owned copy. Enable it only for a trusted, access-controlled deployment
with one active administrator profile, behind HTTPS. Turning the setting off
removes previously persisted browser-owned credentials at the next startup
while preserving operator-owned configuration. As with all localStorage,
same-origin scripts can read these values, so the web origin must be protected
from untrusted scripts and XSS. Before downgrading to a release that predates
this switch, turn it off and start the current release once to scrub the
browser-owned copy.
The web host supports built-in API-key agents only. CLI and ACP agents remain
native-only: they are not shown in the web model picker, stored in browser
credential snapshots, synchronized to the server, or exposed through web
connect routes. Browser requests to credential and AI endpoints allow
loopback/localhost origins by default. A public reverse proxy must separately set
OPENPENCIL_WEB_ALLOWED_ORIGINS to a comma-separated list of exact origins,
for example https://demo.openpencil.dev.
Server persistence does not permit browser-controlled requests to loopback,
private, link-local, metadata, or reserved provider endpoints. A trusted private
deployment that intentionally uses an internal provider must separately set
OPENPENCIL_WEB_AI_ENDPOINT_ALLOWLIST to a comma-separated list of exact URL
origins, for example http://127.0.0.1:11434,https://llm.internal.example.
Or run as a desktop app:
cargo run -p op-host-desktop
Prerequisites: Rust (stable) to build the product. Bun >= 1.0 and Node.js >= 18 are only needed for the web SDK under
packages/.
Docker
Tagged Rust releases publish a single web-host image. The retired TypeScript images with bundled AI CLIs are no longer published.
| Image | Includes |
|---|---|
ghcr.io/zseven-w/openpencil-web:vX.Y.Z |
Rust web host, wasm bundle, and CanvasKit assets |
The web UI exposes built-in agent profiles only; Claude/Codex/OpenCode/Copilot/Gemini CLI tooling is not bundled into Docker images.
Run:
VERSION="$(scripts/workspace-version.sh)"
docker run -d -p 3100:3100 "ghcr.io/zseven-w/openpencil-web:v${VERSION}"
Then open http://localhost:3100/.
Build locally:
docker build -f Dockerfile.web-rust -t openpencil-web-rust .
docker run -p 3100:3100 openpencil-web-rust

Ecosystem
OpenPencil is part of a family of pure-Rust, AI-native tools from ZSeven-W. They compose: jian renders OpenPencil, agent-rs runs its agents, noema remembers, and zode designs from the terminal.
| Project | What it is |
|---|---|
| Zode | Open-source, AI-native coding assistant for your terminal — a fast Rust TUI (ratatui) that reads your code, runs commands, searches files, and manages git. Drives OpenPencil over MCP. |
| agent-rs | A pure-Rust async runtime for shipping LLM agents — multi-provider, tool-capable end-to-end, structured permissions, real MCP, zero unsafe. Powers OpenPencil's built-in agent runtime (vendor/agent) and Zode. |
| jian | Pure-Rust, GPU-Skia UI framework — widgets, layout, events, and hot reload in one stack. Turns a declarative .op document into a native, AI-controllable app with no JS runtime, no DOM, no Electron. OpenPencil's UI framework (vendor/jian). |
| noema | Local-first, non-vector memory system for coding agents. Durable memory as inspectable files, a review queue for new entries, and lexical (embedding-free) recall — works across Zode, Codex, Claude Code, and MCP runtimes. |
Why Rust
OpenPencil was rewritten from the ground up in Rust (#129). The rewrite is complete — the TypeScript + Electron editor was retired at v0.7.5, and the Rust workspace in this repo is the product: one native core that is dramatically smaller and faster, and runs on more platforms from a single codebase.
TypeScript + Electron (retired, v0.7.5) |
Rust (today) | |
|---|---|---|
| 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 | 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-safeon 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-denysupply-chain gating in CI.
Status: the TypeScript editor was retired at
v0.7.5and lives only in git history; this repository is the Rust workspace. The Rust product is under active development (see the Roadmap below).
