Mantine UI

Why Mantine UI?

Mantine goes beyond just offering beautiful components; it ships with over 70 hooks for managing state, forms, hotkeys, scrolling, and more. With its intuitive API design and modern, neutral default styles, Mantine is perfect for rapidly building feature-rich SaaS products.

• Battery Included: Mantine boasts an impressive collection of over 120 components. Beyond basic buttons and inputs, it includes advanced components that often require separate libraries in other ecosystems, such as a Rich Text Editor, Date Range Picker, Notifications, Code Highlighting, and Spotlight.
• Hooks-Driven Development: Mantine provides a standalone @mantine/hooks package that encapsulates common logic like useClickOutside, useHotkeys, and useDebouncedValue, allowing for a clear separation of logic and UI.
• Modern Styling & Customization: Mantine's styling system is highly flexible. The Styles API allows you to precisely target and modify any internal element of a component. It also offers excellent SSR performance, with full support for the Next.js App Router.
• TypeScript First: The entire library is written in TypeScript, providing comprehensive type definitions and support for polymorphic components.
• Tailwind CSS Friendly: Mantine is fully compatible with Tailwind CSS. Since version 7 uses native CSS, you can use Tailwind classes directly in the className prop, giving you the best of both worlds.
• Ready-made UI Blocks: Mantine provides a collection of UI Blocks at Mantine UI featuring 123+ responsive components. These are fully functional, copy-paste ready blocks (like Heroes, Features, and Authentication forms) designed to significantly accelerate your development process.

If you value Developer Experience (DX)—especially if you enjoy using hooks for logic—you will love Mantine.

Code Snippet

Getting started with Mantine is a breeze. Its core philosophy combines hooks for logic with components for rendering, resulting in incredibly clean and concise code.

import "@mantine/core/styles.css";

import { MantineProvider, Button, Modal, Group, Text } from "@mantine/core";
import { useDisclosure } from "@mantine/hooks";

export default function App() {
  const [opened, { open, close }] = useDisclosure(false);

  return (
    <MantineProvider>
      <Group justify="center" p="xl">
        <Button onClick={open} variant="filled" color="blue">
          Open Modal
        </Button>
        <Modal opened={opened} onClose={close} title="Hello Mantine">
          <Text size="sm">
            No need to manually manage visible/setVisible; hooks and components work seamlessly together.
          </Text>
        </Modal>
      </Group>
    </MantineProvider>
  );
}

The snippet above demonstrates the classic Mantine pattern of combining Hooks and Components.

Pros and Cons

No library is perfect; understanding the trade-offs is key to selecting the right tool.

Pros

• Detailed Documentation: Mantine's documentation is widely considered one of the best in the React community, featuring rich examples and lightning-fast search.
• TypeScript: Built entirely in TypeScript, it offers robust type definitions and supports generics, ensuring a smooth development experience.
• SSR Support: Moving away from runtime CSS-in-JS, Mantine v7 excels in Server-Side Rendering (SSR) and initial load speeds.
• Accessibility (A11y): Follows WAI-ARIA standards, with out-of-the-box support for keyboard navigation and screen readers.

Cons

• V7 Migration/Learning Curve: If you are used to the CSS-in-JS pattern of writing sx props directly on components (like in Mantine v6 or Chakra UI), the new classNames and styles API might take some getting used to.
• "Neutral" Default Style: This is both a pro and a con. Compared to the distinct styles of MUI or Hero UI, Mantine's defaults are relatively "plain". If you need a visually striking impact out of the box, you may need to spend time customizing the Theme.
• CSS File Size: While Tree-shaking is supported, the CSS bundle size can be significant if you import all styles without configuration.

Comparison with Other UI Libraries
