If I understand correctly, it's WebSocket on top of Embedded C/C++ web server (civetweb).

Also, the application must find and launch the installed browser. In my opinion, this part is very fragile. On my system, this function (webui/src/webui.c) :

   static bool _webui_browser_exist(_webui_window_t * win, size_t browser);

cannot find my browser.
