The initial release of deepseek-harness-windows-native: DeepSeek Harness in its own native Windows window. No terminal, no browser tab, no browser profiles, no accounts, no sync. Your sessions, your settings, your local files. Exactly like dsh web, minus the browser.

✨ New Features

  • Native window, zero browser involvement: The harness UI renders inside an embedded WebView2 window. No Edge, Chrome or Firefox, and therefore no browser profiles, no sign-in prompts and no sync anywhere near your sessions.
  • Portable single-file executable: One .exe, no DLLs next to it, no .NET installation needed (runtime bundled). Download, double-click, done.
  • Server managed for you: The app boots dsh web --no-open on 127.0.0.1:3080 in the background, and closing the window stops the server. If a server is already running, it attaches to that one instead and leaves it untouched.
  • Always the latest harness: On launch it checks npm and updates the global @deepseek-ai/dsh to the latest release tag (skippable with --no-update).
  • Your data stays yours: Sessions, settings and storages live exactly where they already are, under DSH_HOME (default C:\Users\<you>\.dsh). Nothing is uploaded or synced anywhere.

🚀 Improvements

  • Official DeepSeek branding: Window and taskbar icons use the real artwork, the blue whale from deepseek.com in light mode, the white whale from platform.deepseek.com in dark mode.
  • Theme-aware window chrome: The title bar is recolored to match the app's actual background instead of staying white. Dark app, dark title bar, no startup flash.
  • Versioning in one place: The version lives in a single <Version> entry in the .csproj, and the build scripts name the artifacts from it automatically.
  • Built for developers: Fully open source (MIT), PowerShell build scripts (build_portable.ps1 for the single-file exe), Visual Studio solution + publish profiles.

💻 How to Use

  1. Download DeepSeekHarness-win-x64-2026.09.26.zip (or the .exe) from the assets below.
  2. Unzip it anywhere, then double-click DeepSeekHarness.exe.
  3. Machine requirements: Windows 10/11 x64, the WebView2 Runtime (preinstalled on Windows 11 and most Windows 10 builds), and Node.js with the harness installed once: 
    npm install -g @deepseek-ai/dsh
  4. That's it. The window opens with your existing sessions. The first launch can take a minute (npm check + server boot). Close the window to stop the server, unless the app attached to one you were already running.
