deepseek-harness-desktop

中文 · Releases

An open-source, unofficial Windows Electron wrapper for DeepSeek Harness.

The desktop process starts the official @deepseek-ai/dsh local web server and loads its unmodified UI in a sandboxed Electron WebContentsView. The wrapper only owns process lifecycle, native-window integration, navigation policy, and the custom title bar.

[!IMPORTANT] This is not an official DeepSeek product. It does not provide model credits or bypass API authentication. DeepSeek Harness is currently a Developer Preview; do not open untrusted projects with elevated permissions.

Downloads

GitHub Releases contains the complete NSIS installer, a portable executable, SHA-256 checksums, an explicit source snapshot, and GitHub-generated source archives. Community builds are not commercially code-signed, so Windows may display an unknown-publisher warning. The installer uses the standard per-user application directory to avoid legacy Windows path-length limits. Use the portable build when a custom location is required.

Pinned components

Run from source

Requirements: Windows 10/11 x64, Node.js 24, npm, and PowerShell 5 or newer.

git clone https://github.com/cc1252/deepseek-harness-desktop.git
cd deepseek-harness-desktop
npm ci
npm run setup
npm run start

npm run setup installs the pinned Harness dependency tree, downloads the official Node.js Windows runtime, verifies it against the official SHASUMS256.txt and a repository-pinned checksum, extracts the upstream icon, and generates bundled dependency license notices.

Build Windows releases

npm ci
npm run build:windows

The dist/ directory will contain the NSIS installer, portable executable, unpacked build, and SHA256SUMS.txt.

Security model

• The Harness service listens on a random 127.0.0.1 port.
• The upstream UI uses sandbox: true, contextIsolation: true, and nodeIntegration: false.
• The title bar receives only a narrow minimize/maximize/close IPC bridge.
• Non-local navigation is delegated to the operating system browser.
• Closing the desktop app stops the child Harness process.
