## What it is
HeroUI (formerly NextUI) is an open-source React UI component library built on Tailwind CSS v4 and React Aria Components, offering accessible, fully typed, customizable components for web, plus a React Native variant for mobile. It includes an official CLI, MCP packages for AI coding agents, and machine-readable documentation.

## Use cases
- build accessible react ui components
- styled react component library with tailwind
- react native ui component library
- customize a design system in react
- dark mode theming for react app
- accessible forms and modals in react

## When to choose
- you want polished, accessible React components out of the box with Tailwind CSS v4
- you need both web (React) and mobile (React Native) components from one ecosystem
- you want fully typed APIs, tree-shaking, and deep component customization
- you use AI coding assistants and want MCP/llms.txt documentation support

## When to avoid
- you need a headless/unstyled primitives library rather than pre-styled components
- your project uses Tailwind v3 or React versions older than 19 without migration effort
- you prefer copy-paste component sources (e.g., shadcn/ui style) over a maintained dependency
- you need frameworks other than React/React Native
