MUI Core

MUI Core contains foundational React UI component libraries for shipping new features faster.

  • Material UI is a comprehensive library of components that features our implementation of Google's Material Design system.

  • Joy UI is a beautifully designed library of React UI components.

  • Base UI is our library of "unstyled" components and low-level hooks. With Base, you gain complete control over your app's CSS and accessibility features.

  • MUI System is a collection of CSS utilities to help you rapidly lay out custom designs.


Material UI

Material UI is available as an npm package.


npm install @mui/material @emotion/react @emotion/styled


yarn add @mui/material @emotion/react @emotion/styled
Older versions

Note: @next only points to pre-releases. Use @latest for the latest stable release.

Base UI

Base UI is available as an npm package.


npm install @mui/base


yarn add @mui/base

Note: Base UI is still in beta. We are adding new components regularly and you're welcome to contribute!

Getting started with Material UI

Here is an example of a basic app using Material UI's Button component:

import * as React from 'react';
import Button from '@mui/material/Button';

function App() {
  return <Button variant="contained">Hello World</Button>;

In the interactive demo below, try changing the code and see how it affects the output. (Hint: change variant to "outlined" and color to "secondary". For more options, see the Button component page in our docs.)

Edit Button

Our documentation features a collection of example projects using Material UI.


Premium themes

You can find complete templates and themes in the MUI Store.
