shadcn/ui — Own Your Components

Best for: Teams that want full control over their component code.

The key insight: shadcn/ui isn't a library — it's a collection of copy-pasteable components. You own the code.

npx shadcn-ui@latest add button dialog table

This copies component files into your project. You modify them freely.

Pros:

• Full control (it's your code)
• Tailwind CSS (no CSS-in-JS runtime)
• RSC compatible
• Only ship what you use
• Beautiful defaults (Radix primitives)
• Most popular in 2026

Cons:

• Fewer components than Mantine
• You maintain the components
• No automatic updates
• Requires Tailwind knowledge

Mantine — The Full-Featured Library

Best for: Teams that want the most components and features out of the box.

import { TextInput, Button, Select, DatePicker } from '@mantine/core'

function Form() {
  return (
    <>
      <TextInput label="Name" placeholder="Enter name" />
      <Select label="Country" data={['US', 'UK', 'Canada']} searchable />
      <DatePicker label="Birth date" />
      <Button>Submit</Button>
    </>
  )
}

Pros:

• 100+ components (most of any library)
• Rich form components (DatePicker, MultiSelect, RichTextEditor)
• CSS Modules (no CSS-in-JS runtime)
• Excellent documentation
• Hooks library included (@mantine/hooks)

Cons:

• Larger bundle (even with tree-shaking)
• Opinionated styling (harder to customize deeply)
• Less popular than shadcn in 2026
• Major version upgrades can be painful

Chakra UI — The Styled System

Best for: Teams that like style props and a component-driven design approach.

import { Box, Button, Heading, Text } from '@chakra-ui/react'

function Card() {
  return (
    <Box p={6} borderWidth={1} borderRadius="lg">
      <Heading size="md">Title</Heading>
      <Text mt={2}>Description</Text>
      <Button mt={4} colorScheme="blue">Action</Button>
    </Box>
  )
}

Pros:

• Style props are intuitive (p={6}, mt={4})
• Strong accessibility out of the box
• Good theme system
• Active community

Cons:

• CSS-in-JS runtime (Emotion) — slower than Tailwind
• Server Component support is limited
• Falling behind shadcn in popularity
• Larger bundle size

FAQ

Can I switch between them?

Switching is a significant rewrite. Choose carefully. shadcn/ui is the safest bet — you own the code, so migrating away means updating your own components.

Which is most popular in 2026?

shadcn/ui by a wide margin. It's the default for new Next.js projects.

What about Radix UI directly?

shadcn/ui is built on Radix primitives. Use Radix directly if you want unstyled, accessible primitives without shadcn's Tailwind styling.

Bottom Line

shadcn/ui is the default for new React projects in 2026 — full control, Tailwind-based, RSC-compatible. Mantine when you need rich form components (DatePicker, RichTextEditor). Chakra UI if you prefer style props. Start with shadcn/ui.
