MUI Core

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

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

  • MUI Base 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

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.)

For how-to questions that don't involve making changes to the code base, please use Stack Overflow instead of GitHub issues. Use the "mui" tag on Stack Overflow to make it easier for the community to find your question.


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


Premium themes

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


Read the contributing guide to learn about our development process, how to propose bug fixes and improvements, and how to build and test your changes.
Contributing to MUI Core is about more than just issues and pull requests! There are many other ways to support MUI beyond contributing to the code base.
