@mantine/core

Mantine is a fully featured React component library providing 100+ customizable components, 50+ hooks, and a rich set of utilities for building modern web applications. Mantine stands out for its comprehensive scope — beyond standard UI components, it includes a rich text editor, date pickers, notifications system, spotlight (command palette), carousel, dropzone, and code highlighting. All components support dark mode, responsive styles through Mantine's style system, and deep customization through CSS modules, style props, or the createStyles API. Mantine's hook library (@mantine/hooks) provides 50+ hooks for common UI patterns including useDisclosure, useClickOutside, useHotkeys, useIntersection, useScrollIntoView, useClipboard, and useForm for form validation. The form library (@mantine/form) handles validation, nested objects, list fields, and form state management. Mantine supports server-side rendering with Next.js, Remix, and Gatsby. Components use CSS Modules for styling in v7+, eliminating runtime CSS-in-JS overhead. The design system supports polymorphic components (rendering any element type), composable styles, and theme extension points. Mantine is particularly well-suited for data-rich applications, admin panels, and projects that benefit from a comprehensive, well-integrated component ecosystem.
