DeepSeek Harness Desktop

DeepSeek Harness Desktop for Mac & Windows

  • DeepSeek's open-source, plugin-based agent runtime (MIT licensed)
  • Everything is a plugin: add tools and MCP servers without touching the core
  • Community-built desktop app; Apple Silicon is the best-supported build
  • Prefer the browser? The official Web UI runs with npx @deepseek-ai/dsh web

Best-supported desktop path

The project reports real Harness startup, DMG packaging, code signing and Apple notarization on Apple Silicon. Download from the project release page and still treat the app as an early preview.

Community desktop app · macOS + Windows

DeepSeek Harness Desktop is a community-built app around DeepSeek's local DSH runtime. Apple Silicon has the strongest documented path; Intel Mac and Windows x64 builds need more caution, and Windows ARM64 is not supported.

Use official DSH instead

Independent guide · Releases and documentation checked 18 August 2026.

Choose Apple Silicon for the lowest-friction desktop route. On every other platform, compare the wrapper's current release notes with the official browser-based Web UI before installing.

The app's top-level download copy is broader than its detailed validation section. This table turns those notes into a practical decision.

Documentation mismatch

Do not assume automatic desktop updates are working

The repository's overview advertises automatic updates, while the detailed current-status section says update integration is not finished. Until a release explicitly closes that gap, update manually from GitHub.

  1. 01

    Bookmark the release page

    Use dataelement/dsh-desktop releases, not a third-party mirror.

  2. 02

    Compare the bundled DSH version

    Read the release notes for the bundled @deepseek-ai/dsh version before opening an existing workspace.

  3. 03

    Back up local state before upgrading

    Keep a copy of profiles, plugins and sessions before moving between early desktop builds.

Official fallback

Run the official DeepSeek Harness Web UI

The official route gives you a desktop-like local interface in the browser without adding a community application layer. It requires Node.js and opens locally on port 3080.

  1. 01

    Install a current Node.js release

    The official DSH Web UI uses npx and therefore needs Node.js.

  2. 02

    Run the command in a terminal

    Start the official local Web UI.

    npx @deepseek-ai/dsh web
  3. 03

    Open the local address

    Open http://localhost:3080 if the browser does not open automatically.

    http://localhost:3080
  4. 04

    Add a model provider

    Add a model provider, then start in a disposable workspace.
