Download DeepSeek Harness (DSH) Desktop

A community-maintained desktop distribution with DeepSeek Harness and Node bundled, so no separate Node installation is required. v2.0.9 bundles DSH v0.1.5-rc.1, adds a title-bar remote-control shortcut, and fixes plugin detection and Windows subprocess startup.

DSH Desktop is a community-maintained open-source project, not an official DeepSeek product, and does not represent DeepSeek's position. Upstream Harness upgrades may affect plugins, so back up important configuration first.

Troubleshooting

  1. 1.

    I unzipped it. Now what?

    On macOS, open the DMG and drag DSH Desktop into Applications. On Windows, run Setup.exe and follow the installer. Launch the app, then configure a model, API key, and workspace.

  2. 2.

    Where do I put my API key?

    In the settings panel of the interface. It lands in a local config file, so you only type it once. No key yet? Create one on the DeepSeek open platform. The key stays on your machine and never reaches us.

  3. 3.

    macOS says the developer can't be verified

    Find DSH Desktop in Finder, right-click it, choose Open, and confirm in the system dialog. Download only from the GitHub Release linked on this page; stop if you cannot verify the source.

  4. 4.

    Windows shows "Windows protected your PC"

    After confirming the installer came from the GitHub Release linked here, use More info to inspect the publisher and filename before deciding whether to run it. Do not bypass the warning for an unverified source.

  5. 5.

    The app fails after an upgrade or a Profile will not open

    v2.0.9 retains Quick Recovery with an isolated Safe Mode. Safe Mode creates a separate Profile and data environment and removes that temporary environment after you exit and launch again. Use it to confirm the app itself starts before repairing the original Profile, and back up important configuration first.

  6. 6.

    Can stable and Beta builds coexist?

    Yes, but they share data and configuration. A warning appears when the same Profile is loaded by both stable and Beta builds. Back up important Sessions and configuration before Beta testing.

  7. 7.

    Where is the Linux build?

    The current v2.0.9 Release provides a Windows x64 installer and a macOS Universal DMG. Linux users should follow the official npm installation path and the DeepSeek Harness guide on this site.

  8. 8.

    How do I fully quit?

    Quit DSH Desktop from its app menu or system tray. Exit the running old build before installing an update.

  9. 9.

    How do I uninstall?

    On macOS, remove DSH Desktop from Applications. On Windows, uninstall it from Installed apps. Back up any Profiles, Sessions, and configuration you want to keep before removing application data.

  10. 10.

    Why is the installer relatively large?

    The desktop build bundles Harness, Node, and runtime dependencies, so it does not require a separate system Node installation. It is therefore larger than a normal web client.

  11. 11.

    Can I go back to an older build?

    Harness remains a developer preview. Older installers remain on GitHub Releases, but a newer build may already have migrated data. Back up first, read the relevant release notes, and do not test an old build against your only copy.

What to do after it starts

Model configuration, run modes, permissions and headless setup are all covered in the DeepSeek Harness guide.
