## What it is
Aseprite is an animated sprite editor and pixel art drawing tool for creating 2D game assets, with layers, frames, onion skinning, and palette control. It exports to sprite sheets, GIFs, and PNG sequences, and includes a CLI and Lua scripting for asset pipeline automation.

## Use cases
- draw pixel art sprites for games
- create 2D frame-by-frame animations
- export sprite sheets and texture atlases
- make animated GIFs from pixel art
- edit tilemaps and tile patterns
- automate sprite conversion in a build pipeline
- design retro 8-bit and 16-bit style graphics

## When to choose
- you need pixel-perfect drawing tools like Pixel Perfect stroke and shading ink
- you are authoring animated game sprites with layers and tagged animations
- you want sprite sheet, GIF, or PNG sequence export
- you need scripting or CLI automation for asset generation

## When to avoid
- you need general-purpose photo or vector image editing
- you require high-resolution non-pixel-art digital painting
- you need a free open-source build for commercial use without purchasing a license (source is available but the license is custom)
