## What it is
gka is a Node.js command-line tool that generates high-performance frame animations from a folder of image sequences. It optimizes images (deduplication, blank cropping, sprite-sheet merging, compression) and outputs CSS keyframes animation files with preview support.

## Use cases
- generate css keyframe animation from image sequence
- create sprite sheet animation from png frames
- optimize frame animation images for web
- batch rename and process animation frames
- generate multi-resolution frame animations
- preview frame animation before shipping

## When to choose
- you have numbered image frames and need a lightweight css-based frame animation
- you want automatic sprite-sheet merging and image optimization for animations
- you prefer a one-command cli workflow over manual animation tooling

## When to avoid
- you need video or gif output rather than css/html animations
- you need a gui-based animation editor
- your animation requires runtime scripting beyond css keyframes

## Facets
- artifact type: cli-tool

- function: image-processing, animation, cli, developer-tools
- domain: web-development, frontend, graphics, developer-tools
- platform: cli, cross-platform
