Mantine UI is a React component library that provides more than 120 responsive UI components built on top of the Mantine design system.
The library addresses the need for a cohesive set of pre-built, production-ready components that developers can drop into React applications. Each component is designed to work seamlessly with Mantine's theming system, supporting both dark and light color schemes out of the box. Components automatically respect Mantine theme customizations, allowing developers to maintain visual consistency across their applications without rebuilding common UI patterns from scratch.
Mantine UI suits teams already using or planning to adopt the Mantine ecosystem who want a comprehensive component library with built-in theme support. The breadth of components—over 120—means most common UI needs are covered without reaching for additional libraries. The project is free and open source, removing licensing concerns. However, potential adopters should note that the project does not accept community contributions to its codebase; the maintainers have explicitly stated that pull requests are not accepted unless directly requested by maintainers. Those interested in contributing should direct their efforts to the underlying Mantine library instead.
The project maintains a clear separation between its component showcase website and the core Mantine library, with development activity focused on the component collection itself rather than accepting external code changes. The maintainers have established firm boundaries around the contribution process, prioritizing codebase stability and consistency over community-driven development.
