## What it is
A high-performance Swift library for GPU-accelerated image and video processing built on Apple's Metal, inspired by GPUImage. It provides 80+ built-in filters, filter chaining, camera capture, and video writing for iOS apps.

## Use cases
- apply gpu-accelerated filters to images in ios
- process live camera video with real-time filters
- build a photo editor with filter chains
- record filtered camera output to a video file
- replace gpuimage with a faster metal-based alternative
- render view animations to video

## When to choose
- you need high-performance image/video filtering on iOS with low CPU and memory usage
- you want camera capture, filter processing, preview, and recording in one pipeline
- you need custom Metal-based filters with a GPUImage-like API

## When to avoid
- you target platforms other than iOS, since it requires Metal and iOS 10+
- you need cross-platform image processing
- your project uses Objective-C only, as the library is Swift 5

## Facets
- artifact type: library
