DeepSeek Harness Desktop

> 中文 · English

Put DeepSeek Harness into a native desktop window: double-click to launch, and the window hosts the live UI of your current dsh web profile — agent sessions, tools, plan, goal, subagent, workflow… everything works out of the box. Nothing is re-implemented.

> Everything is a plugin — this repo is the "window".


Features

• 🖱️ One-click launch: desktop shortcut or the in-install launcher — double-click to get the window (white/light by default, dark Codex skin optional)
• 🪟 Native Electron window loading the live UI at http://127.0.0.1:<port>
• ⌨️ Type /desktop in the web UI to open/reuse the window (one window per backend)
• 🔗 External links open in the system browser
• 🛑 Closing the window stops the backend (installer version); without DSH_DESKTOP_LAUNCH, plain dsh web stays browser-first
• 🚀 Startup splash: an instant whale progress window (initializing the backend / loading the UI) hands off to the main window when ready
• 🐋 Official DeepSeek whale icon everywhere (window, taskbar, shortcuts, installer)

Getting started

Option 1: install via git clone (recommended — always the latest code)

Run these in a terminal (Node.js ≥ 22.19 required; git needed; clone to a path without spaces):

git clone https://github.com/Muelsysel/DeepSeek-Harness-Desktop.git
cd DeepSeek-Harness-Desktop
start.cmd

start.cmd automatically: first build (npm install + npm run build) → checks Node.js → checks DeepSeek Harness → registers the plugin (installs it into $DSH_HOME\profiles\web) → creates the Desktop shortcut (whale icon) → launches the window. No file edits needed. The window opens and is ready to use; for everyday use afterwards, double-click the 「DeepSeek Harness 桌面版」 icon on your Desktop (or bin\dsh-desktop.cmd, or /desktop in the web UI).

> To update to the latest code later: git pull, then re-run start.cmd (registration is idempotent and the shortcut is refreshed). > You can also build manually first: npm install && npm run build && start.cmd.

Option 2: zip portable version (no install, no git needed)

Three steps: download → one command → use.

1. Download DeepSeek-harness-desktop-plugin-<version>.zip from GitHub Releases and extract it (Node.js ≥ 22.19 required; pnpm is auto-installed during registration) 2. Open a terminal (any directory) and run one line — replace <extract-path> with your actual extraction location (or just double-click root start.cmd — same effect):

``bat cd /d "<extract-path>" && start.cmd ``

This single command automatically: checks Node.js → checks DeepSeek Harness → registers the plugin (installs it into $DSH_HOME\profiles\web) → creates the Desktop shortcut (whale icon) → launches the window. No file edits needed. 3. The window opens and is ready to use. For everyday use afterwards, double-click the 「DeepSeek Harness 桌面版」 icon on your Desktop (or bin\dsh-desktop.cmd, or /desktop in the web UI).

> Already installed? Re-running this command is safe — registration is idempotent and the shortcut is refreshed. Moved the extraction? Re-run it once to rebuild the shortcut for the new location.

Option 3: setup.exe installer (bundled backend, no environment needed)

1. Download DeepSeek-Harness-Desktop-Setup-<version>.exe from GitHub Releases 2. Run it (no admin required); the app launches automatically when the install finishes 3. No Node.js / pnpm / DeepSeek Harness needed — the backend and the Electron runtime are bundled; the first launch shows progress (built-in dependency init), then it opens instantly

Install location: %LOCALAPPDATA%\Programs\DeepSeek-Harness-Desktop (no spaces). Launch entries: Desktop shortcut (whale icon), Start Menu entry, and a DeepSeek Harness Desktop.lnk inside the install folder — any of the three works. Private data lives in %APPDATA%\DeepSeek-Harness-Desktop (your $DSH_HOME profiles are untouched); closing the window exits the app.

Option 4: manual install into an existing dsh profile (advanced)

Prereq: Node.js ≥ 22.19 (required), pnpm (auto-installed during registration).

:: 1) install into the web profile (registers the plugin + creates the Desktop shortcut)
bin\install.cmd

:: 2) launch every time afterwards (equivalent to DSH_DESKTOP_LAUNCH=1 dsh web)
bin\dsh-desktop.cmd

What bin\install.cmd does:

1. Adds this plugin as a link: dependency of $DSH_HOME\profiles\web via pnpm 2. Appends dsh-desktop to the profile's dsh.profile.bundles (idempotent, with backup) 3. The bundle patch (patch\desktop.bundle.yml) inserts the desktop row; autoOpen is driven by DSH_DESKTOP_LAUNCH 4. Creates the Desktop shortcut "DeepSeek Harness 桌面版" (whale icon)

> You can skip bin\install.cmd: bin\dsh-desktop.cmd checks registration on first click (install-profile.mjs --check: 0 ready / 1 needs install / 2 profile not created yet) and registers once before booting (creating the minimal profile skeleton when needed) — but the Desktop shortcut still needs bin\install.cmd or create-shortcut.cmd.

Usage summary:

> Without DSH_DESKTOP_LAUNCH, plain dsh web keeps its browser-only behavior — no window pops up. > Port: the launcher defaults to --port 0 (OS-assigned, never collides with 3080); set DSH_DESKTOP_PORT to pin a port, or pass --port 3180 directly.

Configuration (plugin version)

Plugin config is overridden at the profile's patch layer (e.g. write a desktop row in cordis.patch.yml):

Environment: DSH_DESKTOP_LAUNCH=1 enables auto-open; DSH_DESKTOP_TITLE overrides the title; DSH_DESKTOP_ELECTRON pins the electron binary (fallback); DSH_DESKTOP_DEBUG=1 writes a debug log to %TEMP%\dsh-desktop-debug.log.

Building from source

:: Plugin zip (tsc build + offline zip: source + lib + node_modules, extract and run)
npm install
npm run build
node scripts\package.mjs        :: → dist\DeepSeek-harness-desktop-plugin-<version>.zip

:: setup.exe installer (NSIS: self-contained app — bundled dsh backend + Electron + splash,
:: no Node/pnpm/dsh on the target machine; downloads the NSIS compiler to tools\ on first build)
node scripts\make-setup.mjs     :: → dist\DeepSeek-Harness-Desktop-Setup-<version>.exe

Dev commands: npm run build / npm run typecheck / npm test (node --test).
