Your agent harness, at home on the desktop.

DSH Desktop runs the official DeepSeek Harness Web UI — untouched — inside native shells for Windows, Linux, macOS, HarmonyOS and Android. The agent host lives in the app itself, talking to the UI over localhost: no cloud relay, no CORS, no account. Tray, notifications and a built-in plugin marketplace included.

DeepSeek Harness running in its native shell.

why a native shell

Why a native shell

The whole dsh experience — none of the browser tab.

100% official DeepSeek Harness — zero upstream changes.

The official Web UI, WebApiClient and every plugin run unmodified. The agent core is never forked, so dsh upgrades land the day they're released.

Local-first, in-process.

The dsh Host runs inside the app and the UI talks to it over localhost. Everything stays on your machine — no cloud relay, no CORS, no account.

A desktop citizen.

System tray, native notifications, native window controls and clipboard image paste. The agent harness behaves like a first-class desktop app — because it is one.

Plugins, one click away.

The built-in visual marketplace (dsh-market) lets you browse and install plugins right inside Settings, live.

Four editions cover Windows, Linux & macOS (Electron), HarmonyOS — where two independent editions ship, Electron on HarmonyOS (keeps Electron) and HarmonyOS (system ArkWeb + embedded Node, no Electron) — and Android (system WebView + embedded Node). Independent open-source shells built on DeepSeek AI's DeepSeek Harness with zero upstream changes.

how it works

One host. One origin. Zero friction.

  1. In-process host

    The shell boots the dsh Host inside the app.

  2. Same-origin UI

    The official Web UI loads from the app's own localhost server.

  3. Official data plane

    dsh's WebApiClient drives it all — HTTP uplink, WebSocket downlink.

No CORS · No auth dance · No custom protocol · Agent core untouched.
