In plain English

Lively is a free, open-source Windows application that lets you use animated content as your desktop wallpaper. Instead of a static image, you can set your desktop background to a video file, an animated GIF, a YouTube stream, a live webpage, a GLSL shader (a type of GPU-rendered visual), or even a Unity or Godot game running silently behind your open windows. The clever part is performance: Lively automatically pauses wallpaper playback when you run a fullscreen app or game, dropping CPU and GPU usage from the animated wallpaper to essentially zero so your games are not impacted. You can also configure it to always mute audio, pause on specific apps, or span a single wallpaper across multiple monitors. Dragging and dropping a video file or a URL directly onto the Lively window is all it takes to set a new wallpaper, no complicated setup required. You would use Lively if you want a visually dynamic desktop on Windows without paying for commercial alternatives. It supports multiple monitors, lets you run different wallpapers on each screen, and includes a library view for browsing your collection. It is built in C# as a WinUI 3 native application, licensed under the Microsoft Public License.
