dsh-desktop

A local-first, cross-platform desktop shell for DeepSeek Harness.

English · 简体中文 · 日本語 · Русский · Español · Português

Beyond official DeepSeek models, DSH Desktop supports mainstream third-party model providers—with more DSH-powered desktop experiences coming soon.

DSH Desktop packages the local DeepSeek Harness web experience as a desktop application. It launches a local Harness instance automatically, manages a random loopback port, persists profiles, plugins, and sessions, and opens the full interface as soon as Harness is ready. Project workspaces are added and managed entirely in the Harness interface.

[!IMPORTANT] DSH Desktop is currently an early preview and depends on the rapidly evolving @deepseek-ai/dsh@0.1.1-rc.1. macOS releases are code-signed and notarized by Apple; current installers are distributed through the official website.

Download

Download DSH Desktop for macOS and Windows from the official website.

Installed macOS and Windows builds check for updates automatically after startup and every six hours. Updates download in the background and prompt you to restart when they are ready. You can also choose Check for Updates… from the application menu.

Why this project exists

DeepSeek Harness already provides a complete agent runtime and Web UI. DSH Desktop does not reimplement Harness; it supplies the host capabilities needed for a desktop product:

• Run without manually starting a CLI or managing local ports
• Create an application-owned Harness launch directory automatically at startup
• Add and manage project workspaces through Harness's built-in directory picker
• Manage the Harness child process, readiness checks, logs, and shutdown in one place
• Store profiles, plugins, and sessions outside the application installation directory so upgrades do not remove user data
• Provide packaging entry points for macOS and Windows

Features

• Opens directly into Harness without an additional landing page
• Starts without an initial directory prompt by creating and reusing an internal launch directory
• Offers retry, log viewing, and exit actions when Harness fails to start
• Provides Harness menu actions for restarting the child process and viewing its log
• Gracefully terminates the Harness child process when the desktop app exits
• Listens only on a random 127.0.0.1 port for each launch
• Removes Node.js privileges from the renderer and enables contextIsolation, sandboxing, and navigation restrictions
• Uses the DSH brand logo consistently in the desktop window and Harness sidebar
• Imports and exports complete custom Agent presets as portable .dshpreset packages, with conflict checks and a trust warning before installation
• Includes a production DSH app icon in macOS ICNS and Windows ICO formats
