dsh-splash-launcher

A one-click Windows launcher for the DeepSeek Harness (dsh) Web GUI with a borderless WPF startup animation (stroke-by-stroke "HARNESS" lettering inspired by SPlayer-Next). It starts dsh web in the background, preloads the real GUI behind the animation, and fades into it only when the GUI is actually ready. Closing the window stops the service it started.

Quick start

Option A: Download the portable build (recommended, no build required)

1. Download dsh-splash-launcher-vX.Y.Z.zip (or just the single-file DSH-GUI.exe) from Releases;
2. Unzip (or drop the exe) anywhere — the exe is self-contained, all splash assets are embedded, a single file is enough;
3. Double-click DSH-GUI.exe.

If SmartScreen shows "Windows protected your PC" on first run: click More info → Run anyway (the exe is unsigned).

Option B: Build from source

build.cmd

Produces a self-contained DSH-GUI.exe (black-whale icon, assets embedded as resources) using the Windows built-in csc.exe (no external toolchain).

Requirements

• Windows 10/11
• Node.js + global npm install -g @deepseek-ai/dsh
• Microsoft Edge WebView2 Runtime (bundled with Windows 10/11 / Edge; standalone installer if missing)

Configuration

• DSH_GUI_WORKSPACE env var, or a workspace.txt next to the exe — working directory for dsh web (default: your user profile %USERPROFILE%)
• DSH_GUI_PORT — port (default 3080)
• Window form is remembered: if you close the window maximized, it reopens maximized next time (only normal/maximized — size and position are not stored; delete %LocalAppData%\DSH-GUI\window.state to reset to the default normal window).
• Splash assets are embedded in the exe; drop the same-named files (splash.html, *.svg, whale.png) next to the exe to override them (custom splash, no rebuild needed).

Known issues

1. Startup takes a while (dsh boot + browser cold start + plugin loading). The animation covers the whole wait and only fades out when the GUI is ready.
