📖 Introduction

Open Cowork is an open-source implementation of Claude Cowork, with one-click installers for Windows and macOS—no coding required.

It provides a sandboxed workspace where AI can manage files, generate professional outputs (PPTX, DOCX, XLSX, etc.) through our built-in Skills system, and connect to desktop apps via MCP (browser, Notion, etc.) for better collaboration.

[!WARNING] Disclaimer: Open Cowork is an AI collaboration tool. Please exercise caution with its operations, especially when authorizing file modifications or deletions. We support VM-based sandbox isolation, but some operations may still carry risks.

📦 Installation

Option 1: Homebrew (macOS, Recommended)

brew tap OpenCoworkAI/tap
brew install --cask --no-quarantine open-cowork

The --no-quarantine flag bypasses macOS Gatekeeper, so you won't see the "Apple cannot verify this app" warning.

Option 2: Download Installer

Get the latest version from our Releases Page.

Platform	File Type
Windows	.exe
macOS (Apple Silicon)	.dmg

Option 3: Build from Source

For developers who want to contribute or modify the codebase:

git clone https://github.com/OpenCoworkAI/open-cowork.git
cd open-cowork
npm install
npm run rebuild
npm run dev

To build the installer locally: npm run build

Security Configuration: 🔒 Sandbox Support

Open Cowork provides multi-level sandbox protection to keep your system safe:

Level	Platform	Technology	Description
Basic	All	Path Guard	File operations restricted to workspace folder
Enhanced	Windows	WSL2	Commands execute in isolated Linux VM
Enhanced	macOS	Lima	Commands execute in isolated Linux VM

• Windows (WSL2): When WSL2 is detected, all Bash commands are automatically routed to a Linux VM. The workspace is synced bidirectionally.
• macOS (Lima): When Lima is installed (brew install lima), commands run in an Ubuntu VM with /Users mounted.
• Fallback: If no VM is available, commands run natively with path-based restrictions.

Setup (Optional, Recommended)

• Windows: WSL2 is auto-detected if installed. Install WSL2

• macOS: Lima is auto-detected if installed. Install command:

brew install lima
# Open Cowork will automatically create and manage a Lima VM (internal Lima name: 'claude-sandbox')

🚀 Quick Start Guide

1. Get an API Key

You need an API key to power the agent. We support OpenRouter, Anthropic, and various cost-effective Chinese Models.

Provider	Get Key / Coding Plan	Base URL (Required)	Recommended Model
OpenRouter	OpenRouter	https://openrouter.ai/api	claude-4-5-sonnet
Anthropic	Anthropic Console	(Default)	claude-4-5-sonnet
Zhipu AI (GLM)	GLM Coding Plan (⚡️Chinese Deal)	https://open.bigmodel.cn/api/anthropic	glm-4.7, glm-4.6
MiniMax	MiniMax Coding Plan	https://api.minimaxi.com/anthropic	minimax-m2
Kimi	Kimi Coding Plan	https://api.kimi.com/coding/	kimi-k2

2. Configure

1. Open the app and click the ⚙️ Settings icon in the bottom left.
2. Paste your API Key.
3. Crucial: Set the Base URL according to the table above (especially for Zhipu/MiniMax, etc.).
4. Enter the Model name you want to use.

3. Start Coworking

1. Select a Workspace: Choose a folder where Claude is allowed to work.
2. Enter a Prompt:

   "Read the financial_report.csv in this folder and create a PowerPoint summary with 5 slides."

📝 Important Notes

1. macOS Installation: If you downloaded the DMG directly (not via Homebrew) and see a security warning, go to System Settings > Privacy & Security and click Open Anyway. Or install via Homebrew to avoid this entirely:

   brew tap OpenCoworkAI/tap && brew install --cask --no-quarantine open-cowork
   

2. Network Access: For tools like WebSearch, you may need to enable "Virtual Network Interface" (TUN Mode) in your proxy settings to ensure connectivity.
3. Notion Connector: Besides setting the integration token, you also need to add connections in a root page. See https://www.notion.com/help/add-and-manage-connections-with-the-api for more details.

❓ FAQ

What is Open Cowork? Open Cowork is a free, open-source desktop application that provides a local AI agent workspace. It wraps AI models (Claude, GPT, Gemini, DeepSeek, etc.) into a GUI with one-click installers for Windows and macOS — no terminal or coding knowledge required.

How is Open Cowork different from Claude Cowork? Open Cowork is the open-source implementation of Claude Cowork. It adds multi-model support (not just Claude), GUI automation via computer use, remote control through Feishu/Slack, and VM-level sandbox isolation. See the feature comparison table for details.

What AI models does Open Cowork support? Claude (via Anthropic or OpenRouter), OpenAI-compatible APIs, and Chinese models including GLM (Zhipu AI), MiniMax, and Kimi. Any provider offering an OpenAI-compatible API endpoint can be configured.

Is Open Cowork free? Yes. Open Cowork itself is completely free and open-source under the MIT license. You only need to pay for the AI model API usage from your chosen provider.

Does Open Cowork work on Linux? Currently, Open Cowork provides pre-built installers for Windows and macOS only. Linux users can build from source — see the Build from Source section.

How does sandbox isolation work? Open Cowork offers multi-level protection: basic path-based restrictions on all platforms, and enhanced VM-level isolation using WSL2 (Windows) or Lima (macOS). When a VM is available, all commands execute inside an isolated Linux environment, protecting your host system.

What are Skills and how do I create custom ones? Skills are built-in workflows for specific tasks like generating PPTX, DOCX, PDF, or XLSX files. Open Cowork ships with default skills under .claude/skills/ and includes a skill-creator tool to help you build your own custom skills.

What is MCP and how does it work? MCP (Model Context Protocol) lets AI connect to external tools and services. Open Cowork supports MCP connectors for browsers, Notion, and other desktop apps — extending the AI's capabilities beyond just file management and code.

How do I set up remote control via Feishu or Slack? Open Cowork supports remote control through Feishu (Lark) and Slack integration, allowing you to send commands and receive results from collaboration platforms. Check the app settings for remote control configuration.

Is my data safe? Does Open Cowork send data to external servers? Open Cowork runs locally on your machine. Your files stay in your workspace. The only external communication is with the AI model API you configure (e.g., Anthropic, OpenRouter). No data is sent to Open Cowork servers.
