Why This Project?

On January 13, 2026, Anthropic released Claude Cowork:

"Introducing Cowork: Claude Code for the rest of your work."

Great product, but:

| | Claude Cowork | DeepSeek Cowork | |--|---------------|-----------------| | Price | 💰 Expensive | ✅ Ultra-low cost | | Accessibility | 🔒 Complex setup, regional restrictions | ✅ Ready to use | | Open Source | ❌ Proprietary | ✅ Fully open source | | Self-hosting | ❌ Not supported | ✅ Supports private deployment |

We want everyone to have access to a great AI assistant — so we built this.

Why DeepSeek?

| Solid Baseline | Ultra Affordable | Fully Open | |----------------|------------------|------------| | Reliable performance among open-source LLMs | Most competitive API pricing | Supports local deployment & customization |

Core Philosophy

Open-source models will eventually catch up with closed-source.

We believe it's only a matter of time. Rather than wait, we're building the infrastructure now.

When open-source models reach parity, DeepSeek Cowork will be ready.

Why Now?

This would have been impossible before. But two things changed:

1. AI Coding explosion - Dramatically reduced development costs, enabling individuals to build complex applications
2. Engineering bridges the gap - Prompt engineering, skill systems, and context management can enhance the experience on existing models

What Can It Do?

Use natural language to have AI help you with:

• 🌐 Browser Automation - Open pages, batch fill forms, extract data, cross-site operations
• 📁 File Management - Browse, organize, and preview your workspace files
• 🧠 Persistent Memory - AI remembers conversation context, understands your habits

Typical Scenarios

| Scenario | Example | |----------|---------| | Data Collection | "Extract prices from these 10 pages and make a spreadsheet" | | Form Filling | "Batch fill registration forms using this contact list" | | Content Organization | "Sort files in my downloads folder by type" | | Monitoring | "Check this page daily and notify me of updates" |

💡 Like having a 24/7 digital assistant at your command

Architecture Highlights

DeepSeek Cowork adopts a unique Hybrid SaaS architecture, combining the best of cloud-based SaaS and local desktop applications:

| Feature | Benefit | |---------|---------| | Zero Server Cost | Static frontend hosted on GitHub Pages, no backend infrastructure needed | | Data Privacy | All user data, settings, and files remain on your local machine | | Unified Experience | Same UI/UX whether using Desktop app or Web browser |

How It Works

1. Desktop Mode: Electron app communicates with LocalService via IPC
2. Web Mode: Browser connects to LocalService via HTTP/WebSocket on localhost:3333
3. CLI Mode: Manage LocalService directly from terminal

The ApiAdapter layer automatically detects the environment and routes API calls appropriately.

Happy Integration

DeepSeek Cowork integrates with Happy, an open-source mobile and web client for AI coding agents.

| Feature | Description | |---------|-------------| | End-to-End Encryption | All messages are encrypted locally before transmission - your data never leaves your device unencrypted | | Mobile Access | Use the Happy App (iOS / Android) to monitor and control AI tasks on the go | | Push Notifications | Get alerted when AI needs permission or encounters errors | | Open Source | Fully auditable code with no telemetry or tracking |

DeepSeek Cowork uses Happy's account server for session management and encrypted sync across devices.

Core Components

| Component | Description | |-----------|-------------| | Claude Code | Original Claude Code integrated as Agent kernel with all features and capabilities | | Happy | Open-source AI session management with E2E encryption and mobile app support | | JS Eyes | Browser extension for tab control, script execution, data extraction | | Electron App | Cross-platform desktop interface integrating all components |

Quick Start

git clone https://github.com/imjszhang/deepseek-cowork.git

Build Web Version

# Build static files for web deployment
npm run build:web

# Output: docs/app/

The web frontend is deployed to GitHub Pages automatically.

Building Desktop Clients

Build standalone installers for Windows, macOS, and Linux:

# Build for current platform
npm run build

# Build for specific platform
npm run build:win    # Windows (NSIS installer + portable)
npm run build:mac    # macOS (DMG, Intel + Apple Silicon)
npm run build:linux  # Linux (AppImage, deb, rpm)

# Build for all platforms
npm run build:all

Built packages will be output to the dist/ directory.

Version Management

The project uses semantic versioning (SemVer). Current version: V0.1.25

Update version numbers:

npm run version:patch   # 0.1.0 → 0.1.1 (bug fixes)
npm run version:minor   # 0.1.0 → 0.2.0 (new features)
npm run version:major   # 0.1.0 → 1.0.0 (breaking changes)

The version number is automatically synchronized to:

• package.json - Source of truth
• renderer/index.html - UI display (auto-updated during build)
• Application runtime - Dynamically loaded from package.json

Browser Extension

Browser automation requires the JS Eyes extension.

Installation

1. Download JS Eyes
2. Open browser extension page
   • Chrome: chrome://extensions/
   • Edge: edge://extensions/
   • Firefox: about:debugging
3. Enable "Developer mode"
4. Click "Load unpacked" and select the extension folder for your browser
5. Make sure DeepSeek Cowork is running, extension will auto-connect
