## What it is
Material UI is a comprehensive open-source React component library implementing Google's Material Design, MIT-licensed and production-ready. It includes prebuilt accessible components, theming and customization via the sx prop, and is backed by a decade of development from thousands of contributors.

## Use cases
- build a react app with material design components
- react ui component library for dashboards
- prebuilt react buttons, dialogs, and forms
- customize a react design system with theming
- react dashboard or marketing page templates
- accessible react components out of the box

## When to choose
- you want production-ready, battle-tested React components following Material Design
- you need a mature library with a huge community and long-term support
- you want built-in theming, dark mode, and accessibility
- you need free templates for dashboards, sign-in, or checkout flows

## When to avoid
- you need a fully custom, non-Material visual identity from scratch
- you want unstyled headless components only (consider Base UI)
- you need advanced components like data grids or date pickers without a commercial MUI X plan
- you are not using React

## Facets
- artifact type: library
- maturity: stable
- function: ui-components, css-framework, frontend-framework, theme
- domain: web-development, frontend, web-design, developer-tools
