[Show and tell] DeepSeek Harness Desktop — a self-contained Windows app

[SpxZhu]

Hi everyone! I’ve been working on DeepSeek Harness Desktop, an experimental Electron desktop shell for DeepSeek Harness.

The goal is to make the existing Harness Web experience easier to launch and use on Windows—without requiring users to install Node.js, pnpm, or clone the source repository.

What it does

• Starts the existing DeepSeek Harness web profile locally
• Opens it in a dedicated Electron window
• Packages the Harness backend and a pinned Node.js runtime
• Shares sessions, settings, and credentials with the CLI through the default DSH_HOME
• Shuts down the complete backend process tree when the app closes
• Restricts in-app navigation to the local Harness backend and opens external links in the system browser

The desktop shell deliberately reuses the existing agent, session, tools, configuration, and Web implementations. It is a compatibility layer rather than a separate Harness frontend.

Windows installer

The project can produce a self-contained Windows x64 NSIS installer. A GitHub Actions workflow also builds and verifies the installer on every push.

You can find the implementation and build instructions here:

Current limitations

This is still an early version:

• Windows x64 only
• No code signing yet, so Windows may display a security warning
• No automatic updates
• No system tray, file associations, or custom title bar
• The app currently loads the local HTTP Web interface rather than using a dedicated Electron IPC client

I’d love to hear your feedback:

• Would a desktop distribution make DeepSeek Harness easier for you to use?
• Which platform should be supported next?
• What desktop-specific features would be most valuable?
• Would you prefer a lightweight shell like this or a deeper native desktop integration?

Feedback, testing, and contributions are very welcome!
