## What it is
Reflexjs is a React styling library for rapid UI development using style props, themes, variants, and color modes, based on the System UI specification. It ships with starter kits, themes, and copy-paste blocks for building Next.js and Gatsby sites faster.

## Use cases
- style react components with css props
- add dark mode to a next.js site
- build a design system with theme tokens and variants
- create responsive mobile-first styles quickly
- bootstrap a gatsby site with starter kits and blocks
- replace theme ui with a zero-runtime styling library

## When to choose
- you build React apps with Next.js or Gatsby and want fast prop-based styling
- you need theming, variants, and color modes without runtime overhead
- you want copy-paste blocks and starter kits to scaffold sites quickly

## When to avoid
- you need a full component library with prebuilt accessible components
- your project uses Vue, Svelte, or non-React frameworks
- you need a library under heavy active development - releases have slowed
