A downloadable desktop tool

OpenAnima v1.0 is out

OpenAnima is an open-source desktop overlay engine for Windows.

It lets you place animated GIFs, APNGs, WebM videos, sprites, pixel-art characters, HUD elements, frame animations, and other local 2D assets directly on your desktop as movable overlay windows.

The goal is simple: turn the desktop into a small interactive visual playground.

Included in v1.0

  • Windows EXE release
  • Asset Library and Desktop Inspector
  • GIF, APNG, WebM, sprite strip, spritesheet, and HUD support
  • Safer config persistence and recovery tools
  • Diagnostics and runtime logging
  • Overlay actions and movement physics
  • Improved asset setup workflow
  • Better recovery for broken or hidden overlays

Supported asset types

  • GIF overlays
  • APNG animations
  • WebM overlays
  • PNG / JPG / WEBP images
  • Frame-folder animations
  • Sprite strips
  • Spritesheets
  • Composite UI / HUD assets

OpenAnima v1.0 focuses on creating a stable and flexible 2D desktop overlay system for Windows while keeping everything local and lightweight.

Future updates will focus on:

  • better polish
  • stronger asset workflows
  • creator-focused tools
  • experimental 3D desktop objects
