MUI

React component library implementing Material Design

As of 29 August 2026, MUI is free to use. The most widely used React component library. Softwr lists it under Web Development. MUI is available on Web.

Overview

What MUI does

MUI is a React component library implementing Google’s Material Design, and one of the most widely adopted component libraries in the React ecosystem. It provides a large set of accessible, tested components — data grids, date pickers, autocomplete, dialogs — that would each take real effort to build well. Its theming system allows substantial visual departure from stock Material Design, though teams often report that escaping the Material look entirely is more work than expected. Some advanced components sit behind a commercial licence.

What people use it for

  • Building an admin or internal application quickly with components that already work
  • Teams needing accessible complex widgets without building them
  • Products where Material Design is an acceptable or desired starting point

The honest half

Where it falls short

Concrete and checkable, so you can decide whether any of them matter to you. This is the half of a review a vendor will not write about MUI.

  • Escaping the Material Design look takes more theming effort than teams expect
  • Bundle size is significant, and careless imports pull in far more than needed
  • Advanced components such as the full data grid require a paid licence
  • Major version upgrades have historically required real migration work

Questions people ask

Each answer names the page it came from, so you can check it rather than take our word for it.

Is MUI free?

The core library is open source and free. Advanced components, including the full-featured data grid, require a paid licence.

Can MUI look non-Material?

Yes, through the theming system, but a substantial departure takes real work. Teams wanting full design control often prefer unstyled primitives instead.

Does MUI handle accessibility?

Components follow WAI-ARIA patterns by default, which is a large part of why teams adopt it.

Softwr does not host reviews and shows no star rating for MUI, because a rating we did not collect is not ours to publish. What is here is the pricing and platform detail from the vendor’s own pages, limitations we could state concretely, and alternatives a reviewer confirmed people weigh against it.
