Isilsolme/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 or Google Chrome

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)
• 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. The taskbar briefly shows the Chrome/Edge default icon before the page favicon (black whale) loads; this is a browser-level placeholder and cannot be preset via command line.
2. 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.
3. Unsigned launchers that start hidden processes / stop process trees may trigger SmartScreen or behavior-based antivirus heuristics; click "More info → Run anyway" on first run, add the folder to your AV exclusions, or code-sign the exe.
