Material UI

Material UI (MUI) is the most complete React component library available. Data grids, date pickers, autocomplete, dialogs, form controls — it covers every enterprise UI pattern out of the box. The theming system is flexible enough to override Material Design's look entirely.

For internal tools and enterprise applications where shipping fast matters more than pixel-perfect custom design, MUI is the pragmatic choice. The component quality is high, accessibility is built in, and the documentation is excellent. Combine it with Tailwind for custom sections where the component library doesn't fit.
