## What it is
A React library that renders React components to HTML5 <canvas> instead of the DOM, using hardware-accelerated canvas for smooth mobile web app performance. It provides components like Surface, Layer, Group, Text, Image, Gradient, and ListView for building application UIs.

## Use cases
- build high-performance mobile web apps with smooth scrolling
- render React UI to canvas instead of DOM
- avoid slow DOM rendering on mobile devices
- create fast touch-scrolling lists on mobile web
- efficiently render multi-line truncated text
- optimize rendering of long lists with cached drawing

## When to choose
- you're building a mobile web app where DOM performance is a bottleneck
- you need smooth 60fps scrolling and animations on mobile browsers
- you want React component ergonomics with canvas rendering
- you need efficient multi-line text truncation that's expensive in DOM

## When to avoid
- you're building a standard desktop web app where DOM is fast enough
- you need accessibility features like screen readers or text selection
- you need SEO or server-side rendering of content
- you're building data visualizations or games (other canvas libraries fit better)
- you need a library with active development and modern React support
