Your desktop but alive.

Animated sprite companions that walk, idle, and play across your screen. Run the ones bundled with the demo, or build your own. No code required.

What is in the demo

A focused build you can actually use today, on macOS and Windows.

Ready-made pets

19 pets and 27 objects ship with the demo. Toggle one on and it walks your desktop right away.

Visual behavior editor

Wire Start, Idle, Walk, and Random nodes into a behavior graph that decides what your pet does.

Importer and slicer

Bring in PNG sequences, GIFs, or sprite sheets, and slice a grid image into clean frames.

macOS and Windows

Native window rendering on both platforms keeps pets smooth, transparent, and light.

Two ways to enjoy Screen Pet Engine. Start wherever you like.

For players

Just want fun desktop companions? Turn a pet on, drag it around, and let it roam. You never need to open the editor.

For creators

Want to build your own? Import your artwork, wire up a behavior graph, preview it live, then add it to your library.
