Material UI vs Semantic UI
Which should you use? A side-by-side look at what each one does, who it suits, what it costs, how hard it is to set up, and where each falls short.
Open source · MIT
A React component library of ready-made UI pieces built on Google's Material Design.
Open source · MIT
A CSS and JavaScript UI component framework built around theming and readable HTML.
Our verdict
Material UI is a React-only component library that gives you a consistent, prebuilt set of interface pieces in Google's Material Design style, and it is actively maintained. Semantic UI is a framework-agnostic CSS and JavaScript toolkit focused on theming through CSS variables and simple HTML markup, with the setup being easier for beginners but its development pace has slowed. Pick based on whether you are building in React and want Material Design, or want a theme-driven look with less React dependence.
Pick Material UI if you are building a React app and want a large, well-documented set of components that follow Material Design.
Pick Semantic UI if you want prebuilt components you can restyle through CSS variables and you are not committed to React or Material Design.
| Key difference | Material UI | Semantic UI |
|---|---|---|
| Framework fit | Built specifically for React; does not help with other frameworks. | Styled with CSS and JavaScript; can be integrated into React, Angular, Meteor or Ember. |
| Default look | Recognizably Material Design; restyling takes extra work. | Designed for theming with many customizable CSS variables and inheritable settings. |
| Setup | Intermediate difficulty; installed with a package manager. | Beginner difficulty; full customization relies on a Gulp and Node build workflow. |
| Activity | Last code update in the last day; mature project with thousands of contributors. | Latest release noted is October 2022; last push November 2024, so slower activity. |
| Support | Large, documented component set; advanced components live in the separate MUI X project. | Help is linked to external sites like Gitter and StackOverflow rather than GitHub Issues. |

Who each one is for
Choose Material UI if you need…
- React developers who want a consistent, prebuilt set of UI components
- Teams that want to follow Material Design guidelines
- Projects that need a large, documented component set
- Developers who want to extend basic components with more complex ones from the companion MUI X library

What each one is
Material UI
Material UI is a collection of React components, such as buttons, menus and form controls, that follow Google's Material Design visual system. Developers add these pieces to a React web app instead of building every interface element from scratch. The README describes it as a mature project with thousands of contributors and an MIT license.
Semantic UI
Semantic UI is a front-end framework that provides ready-made interface pieces such as buttons, menus, grids, dropdowns and popups, styled with CSS. Its README describes it as designed for theming, with many customizable CSS variables and a layered system where settings can be inherited and overridden. It is meant to help developers build responsive web pages using simple HTML markup and JavaScript.
Best for
Material UI
- React developers who want a consistent, prebuilt set of UI components
- Teams that want to follow Material Design guidelines
- Projects that need a large, documented component set
- Developers who want to extend basic components with more complex ones from the companion MUI X library
Semantic UI
- Front-end developers who want prebuilt UI components they can restyle with themes
- Teams building responsive websites that need to work across many devices
- Developers integrating a UI layer into React, Angular, Meteor or Ember projects
- Projects that want to customize the look through CSS variables rather than rewriting styles
Strengths
Material UI
- Large, well-documented component set based on a known design system
- Long development history and a large contributor base, according to the README
- Free under the MIT license
Semantic UI
- Large set of prebuilt components (the README lists 50+ UI elements) with many CSS variables for theming
- Uses MIT license, which permits free commercial and personal use
- Includes official packages for CSS-only, LESS and several frameworks
Not ideal for
Material UI
- People who are not writing React code, since the library is built for React specifically
- Teams that want a completely custom visual style without Material Design, because the components follow that look by default
- Beginners with no JavaScript or React background, who should learn the basics first
Semantic UI
- Projects that must support Internet Explorer 9 or older browsers, because the README says grids and flexbox components may not display correctly there
- Developers who want the newest component approach; the latest release noted in the README is from October 2022 and the last push was November 2024, so activity may be slower than mainstream alternatives
- Anyone who needs a support forum on GitHub, since the README asks users to avoid usage questions in Issues and to use Gitter or StackOverflow instead
Trade-offs
Material UI
- Tied to React, so it does not help with other frameworks
- Its default look is recognizably Material Design, which takes extra work to restyle
- Advanced components are in a separate project, MUI X, which may need its own setup
Semantic UI
- The README points to a 2022 release as the most recent, and browser support for older systems is limited
- Relies on a build workflow (Gulp, Node) for full customization, which adds setup work for beginners
- Documentation and community support are linked to external sites, so answers may be spread across several places
