DeepSeek Harness Desktop

A one-click desktop application for DeepSeek Harness. Double-click the icon and start using it — no need to open a terminal or cd into the git repository every time.

Note: This is a companion launcher for the DeepSeek Harness developer preview. DeepSeek Harness itself is iterating rapidly and there will be compatibility-breaking changes.

✨ Features

• One-click launch — Detects the Harness service (default http://127.0.0.1:3080). If it is not running, the app starts it in the background using the repository’s node --import tsx/esm apps/cli/src/bin.ts web command, waits until it is ready, and opens the Web UI inside the app window.
• Runs in the background — Closing the window minimizes to the system tray and the Harness service keeps running. Choose Exit (Stop Harness) from the tray menu to stop the process started by this app.
• Never hijacks an existing service — If you already started Harness manually, the app reuses it and will not kill it on exit.
• Single instance — Launching the app again focuses the existing window instead of starting a second server.
• F12 opens the developer tools inside the window.

🚀 Quick Start

Option 1: Install the packaged application (recommended)

1. Download the installer from the Releases page: DeepSeek Harness 桌面端 Setup 1.0.0.exe
2. Run the installer. A DeepSeek Harness shortcut is added to your desktop and Start Menu.
3. Double-click the shortcut. That’s it.

Option 2: Run from source (for development)

cd "D:\DeepSeek Harness 桌面端"
npm install --cache "D:\DeepSeek Harness 桌面端\.npm-cache"
npm start

Build the installer yourself

.\build.ps1    # one-click build (handles dependencies, Electron binary, and toolchain cache)

The build.ps1 script automatically prefetches the winCodeSign / NSIS / nsis-resources toolchain into %LOCALAPPDATA%\electron-builder\Cache, which avoids extraction failures caused by missing symbolic-link privileges on some Windows accounts.

⚙️ Configuration

The app reads its settings from %APPDATA%\dsh-desktop\settings.json:

{
  "repoPath": "C:\\Users\\tianj\\deepseek-harness",
  "port": 3080
}

Environment variables DSH_DESKTOP_REPO and DSH_DESKTOP_PORT override these values. If startup fails, a dialog lets you pick another repository directory or retry.

📋 Requirements

• Windows 10/11
• Node.js >= 22 installed
• The DeepSeek Harness repository, already set up with pnpm install && pnpm run build

🗂 Logs

Runtime logs are written to %APPDATA%\dsh-desktop\logs\harness.log.

🔌 DSH Plugin

This repository also ships a cordis plugin for DeepSeek Harness — dsh-desktop-launcher: it adds a Desktop card to the DSH Web UI settings page that detects the desktop app and launches it with one click.

dsh plugin --profile web add dsh-desktop-launcher

See packages/desktop-launcher-plugin/README.md for details.
