Preface¶

DeepSeek Harness (dsh) is an agent framework open-sourced by DeepSeek AI. The official repository summarizes its architecture in one sentence: Everything is a plugin. The official setup path for its web interface is straightforward: first install Node.js, then run npx @deepseek-ai/dsh web, and access http://127.0.0.1:3080 via your browser.

This path works well for users already familiar with the CLI, but it may not be convenient on Windows. Each time you need to open a terminal, wait for npx to run, then switch to the browser, and closing the window often risks losing active sessions. As a result, a number of desktop wrappers have emerged in the community that package the official Web UI into standalone windows.

deepseek-harness-desktop is one such project. Maintained by chyra-moon, it is open-sourced under the MIT license and categorized under “Interface Enhancements” in the community plugin directory. The pinned note on its repository README clearly states: this is a community-driven project, not an official offering; the copyright of DeepSeek Harness itself and the @deepseek-ai/* packages remains with deepseek-ai. The community directory site https://deepseek-harness-plugin.com is also an independent platform and has no official affiliation with DeepSeek / Fangtian.

What is this?¶

In one sentence: this is an Electron desktop wrapper for Windows x64 that loads the official dsh web UI 1:1 into a standalone window, and additionally hosts or reuses the official dsh server.

Its goal is to solve the problem of “how to double-click to open the official interface on Windows”, rather than building a completely new cloned interface. The directory page description matches the GitHub repository blurb: a Windows desktop wrapper that is a 1:1 replica of the official web interface. As of 2026-08-18, both the directory page and GitHub repository have 11 stars; the current released version is v0.1.0, the primary language is JavaScript, and the packaged target is only Windows x64.

Core Features¶

Based on the repository README, v0.1.0 Release notes, and the src/main.js source code, the following capabilities have been verified:

Zero-configuration startup. The installation package includes the Electron runtime and dependencies. The README states that there is no need to install Node.js separately or type commands—just install and double-click to launch the official interface. The loaded interface is the official frontend, not a cloned skin.
Built-in server, with support for reusing existing instances. The application first detects 127.0.0.1:3080: if the web version or CLI is already running, it will directly reuse the existing instance for shared session data; otherwise, it will spin up a built-in @deepseek-ai/dsh server. The current package.json locks this dependency to version 0.1.0-rc.6. If the built-in entry point is missing or fails, it will automatically fall back to npx -y @deepseek-ai/dsh web.
Disconnection self-recovery. It performs health checks every 5 seconds during runtime; if the external server is shut down, the application will take over and restart it within approximately 5 seconds, then automatically reload the page. The source code comments note that this is intended to avoid the scenario where “the interface is still up but messages cannot be sent”.
Desktop wrapper behavior. System tray residency, window position memory, single-instance lock, automatic restart after crash, and a clean window without a menu bar. Closing the window defaults to minimizing it to the system tray, and right-clicking the tray icon allows you to exit or view the about information.
Whale loading animation on startup. The README explains that the animation uses the official whale icon with blue/white light dots, with aligned details for the belly, eyes, and water splashes, plus a breathing undulation effect. The v0.1.0 Release also mentions the sidebar hover behavior: it automatically collapses after opening, expanding when the mouse hovers over it and collapsing when the mouse moves away.

The key shortcuts are consistent across both the README and the main process code:
- Ctrl+Shift+I: Developer tools
- Ctrl+R / F5: Reload page
- Ctrl+Shift+O: Open the current server address in your system browser

Installation and Activation¶

The installation command provided on the community directory can be run in a DeepSeek Harness terminal:

dsh plugin add github:chyra-moon/deepseek-harness-desktop

For a reproducible installation, pin the commit hash as specified on the directory page:

dsh plugin add github:chyra-moon/deepseek-harness-desktop#commit

The directory page also reminds users that the plugin runs with the permissions of the current dsh process, and may execute code during installation. Please review the source code repository and license before installing.

In terms of the actual structure of this repository, the README frames the daily usage path as “download the Windows installation package, double-click to launch”. The repository root is a standalone Electron application (with src/main.js as the entry point), rather than a skin layered on top of an existing dsh web instance. If your goal is a standalone desktop window, installing from GitHub Releases aligns better with the project’s stated purpose.

v0.1.0 offers three packages, all only for Windows x64:
1. Installer (recommended in README): DeepSeek.Harness-0.1.0-x64.exe, which creates desktop and Start Menu shortcuts.
2. Extractable archive: DeepSeek.Harness-0.1.0-win32-x64.zip, usable immediately after extraction, with a progress indicator during extraction.
3. Portable standalone executable: DeepSeek.Harness-0.1.0-portable-x64.exe, a single file; it will decompress in the background for several minutes on first launch, with no progress indicator.

To run from source code, you will need Node.js and npm installed locally. The README notes that you must first generate icons before first use:

npm run icon
npm install && npm start

You can use npm run dist to package the application. When the official dsh releases a new version, the repository will open an upgrade PR via Dependabot; after merging, run npm run update:dsh to rebuild the package.

Typical Usage Scenarios¶

Install and double-click to launch. The window will first display a status page while the backend detects or starts the dsh server, then load the official frontend once ready. The source code hints that first launch or reusing an external server may take several seconds to tens of seconds.
If you are already using the web version or CLI, you can run the official command as normal first:

    npx @deepseek-ai/dsh web

Then open the desktop version. The application will reuse the existing official server on `127.0.0.1:3080` for shared session data across both instances. The README also notes: if you want to stay on the latest official version, run the latest `npx @deepseek-ai/dsh web`, and the desktop version will automatically reuse it.

Closing the window does not equal exiting. By default, it will minimize to the system tray; to fully exit, use the “Quit” option in the right-click tray menu.
If you do not want the window to minimize to the tray when closed, edit settings.json in your application data directory:

    {
      "closeToTray": false
    }

If the workspace picker fails to open in a remote desktop environment, switch to the in-app browsing picker by modifying the same file:

    {
      "directoryPicker": "browse"
    }

The default value is `"native"`, which uses the Windows native dialog. This switch in the source code will make dsh use the in-app picker to avoid crashes of the native dialog worker in remote desktop sessions.

Applicable Scenarios and Notes¶

This project is suitable for Windows x64 users who want to double-click to launch the official dsh web interface, as well as users already using dsh web / CLI who want to use a desktop window with shared session data from their existing instance. Using the installer package means you do not need to configure Node.js beforehand.

Current repository badges and packaging configurations only list Windows x64 support; macOS, Linux, and Windows ARM are not within the stated scope. It is also not intended to be understood as an official client—the README’s pinned note clearly states that this is a community project and not an official offering.

Before using, we recommend verifying the following points:
1. Review the source code and license before installing. This project uses the MIT license. The community directory notes that the plugin runs with the permissions of the current dsh process and may execute code during installation. The desktop version will spin up or reuse a dsh server on your local machine, with permission boundaries equivalent to the official web version—do not treat it as a sandbox.
2. Antivirus software may flag it as malicious. The README attributes this to common false positives for community unsigned applications, and recommends auditing the source code or building from source yourself.
3. The built-in dsh version will lag behind the latest official release. The current package.json depends on @deepseek-ai/dsh version 0.1.0-rc.6. The official repository notes that DeepSeek Harness is still in developer preview, and compatibility-breaking changes may occur. To use the latest official version, first run npx @deepseek-ai/dsh web so the desktop wrapper can reuse the external server.
4. The portable version will have a slow first launch with no progress indicator, which the README notes is normal; the extractable archive provides more transparent progress.

Summary¶

deepseek-harness-desktop does one specific thing: adding a double-clickable wrapper for the official web interface on Windows, with support for spinning up its own server or reusing an existing instance, and it will attempt to restart the server if the connection drops. It does not replace dsh’s plugin ecosystem, nor does it modify the official frontend.
