 # Desktop
 
-One of Dioxus' killer features is the ability to quickly build a native desktop app that looks and feels the same across platforms. Apps built with Dioxus are typically <5mb in size and use existing system resources, so they won't hog extreme amounts of RAM or memory.

-Dioxus Desktop is built off Tauri. Right now there aren't any Dioxus abstractions over keyboard shortcuts, menubar, handling, etc, so you'll want to leverage Tauri - mostly [Wry](http://github.com/tauri-apps/wry/) and [Tao](http://github.com/tauri-apps/tao)) directly. The next major release of Dioxus-Desktop will include components and hooks for notifications, global shortcuts, menubar, etc.
