dsh-web-manager

Using DeepSeek Harness WebUI on a Windows desktop used to mean repeatedly typing commands to start the service, memorizing port numbers, hunting for the right browser tab, and starting over every time the process died. dsh-web-manager tucks all of that into a persistent system tray: double-click the desktop shortcut and a standalone window with no address bar and no tabs pops up instantly, with dsh web auto-launched and continuously guarded behind the scenes. Close the window and the service keeps running; click the tray icon and the window is back wherever you left it. The entire lifecycle no longer requires manual intervention.

At its core, the plugin makes the WebUI behave like a native desktop application. The window runs in Edge --app standalone mode or, from v3.8 onward, an embedded WebView2 mode, both carrying the official whale icon on the taskbar and window, with a dedicated browser data directory fully isolated from the everyday browser. Window size and position are remembered per instance and applied via a geometric hook before the window becomes visible, so the first rendered frame already has the correct geometry with zero visible jump. Multiple instances can be managed simultaneously, mixing Windows and WSL backends on different ports, each with independent port, window, guard, and browser profile. The WSL2 backend supports both a self-healing wrapper script and systemd unit modes, with automatic distro detection and per-backend port memory. The Runtime Bridge lets the tray read the authoritative dsh state and stop the service gracefully via SIGTERM before kill, instead of a blunt process kill. The tray menu includes one-click updates for both dsh and the manager itself, and neither update interrupts running services.

This plugin is for anyone who uses DeepSeek Harness daily on a Windows desktop, especially developers who run dsh inside WSL2 and want a native-level WebUI experience straight from the desktop. If you are tired of manually managing services, tracking port numbers, and digging through browser tabs, this is built for you.
