What is shadcn/ui? How to Choose Between MUI, Chakra, and Ant Design

What is shadcn/ui? How to Choose Between MUI, Chakra, and Ant Design

Introduction: Last month I took over a legacy project, opened the package.json and saw Material-UI 5.x staring back at me. My heart sank a little. It’s not that MUI is bad - it’s that this project needed to look nothing like Material Design. I was about to start wrestling with MUI’s theming system again. Then I remembered shadcn/ui - the component library that made me think “this is exactly what I need” the first time I used it.

---

1. shadcn/ui: A Component Library That’s Not a Component Library

1.1 The Copy & Own Philosophy

shadcn/ui is interesting - it’s not even an npm package.

You won’t see a command like npm install shadcn-ui. Instead, it gives you component code that you copy directly into your project. Copy, paste, and that code becomes yours.

Honestly, when I first saw this concept, I was skeptical: won’t copying code into my project create a mess?

But after using it, I realized this approach is actually brilliant.

The traditional component library pattern goes like this: install package -> import component -> configure styles via props and theme -> hit customization needs and start working around - wrapping components, overriding styles, writing a pile of workarounds.

shadcn/ui cuts through this entirely. Need to change something? Just modify the component code directly. Because the code is in your project, there’s no “black box.”

1.2 Technical Architecture: A Three-Layer Cake

shadcn/ui’s tech stack is essentially three layers:

Bottom Layer: Radix UI

This is a set of “unstyled” component primitives. What does unstyled mean? It handles behavior and accessibility, but not appearance. For example, a Dialog component - Radix is responsible for:

• Open/close state
• Focus management (tab key navigation)
• ARIA attributes (screen reader support)
• Keyboard interactions (Esc key to close)

But styling? None at all. A blank canvas.

Middle Layer: Tailwind CSS

Radix gives you the skeleton, Tailwind gives you the skin. Each shadcn/ui component comes with styles written in Tailwind utility classes. You can modify these classes directly without “overriding” anything.

Top Layer: Your Modifications

This is the essence of shadcn/ui. The component code is in your hands - customize it however you want. No API limitations, no props that can’t reach certain places.

// shadcn/ui's Button component (code lives in your project)
const Button = React.forwardRef<HTMLButtonElement, ButtonProps>(
  ({ className, variant, size, ...props }, ref) => {
    return (
      <button
        className={cn(buttonVariants({ variant, size, className }))}
        ref={ref}
        {...props}
      />
    )
  }
)

// Want to change it? Just modify directly
// For example, adding a custom animation
const Button = React.forwardRef<HTMLButtonElement, ButtonProps>(
  ({ className, variant, size, ...props }, ref) => {
    return (
      <button
        className={cn(
          buttonVariants({ variant, size, className }),
          "transition-all duration-300 hover:scale-105" // Add directly
        )}
        ref={ref}
        {...props}
      />
    )
  }
)

See? No sx prop, no styled() - just modify the classes directly.

1.3 Performance Advantage: Numbers Don’t Lie

shadcn/ui’s performance advantage is genuinely noticeable.

I ran some numbers through Bundlephobia:

Why is shadcn/ui so small? Because you only bundle the components you actually use - unused components never make it into your bundle. Plus, there’s no CSS-in-JS runtime overhead - Tailwind processes styles at build time.

In a real project, migrating a medium-sized app from MUI to shadcn/ui, I saw the bundle size drop from 1.2MB to around 600KB. That’s a significant difference.

1.4 The Trade-off: Maintenance Responsibility Is Yours

shadcn/ui isn’t perfect.

Code in your hands means maintenance responsibility is in your hands too.

When MUI releases a new version fixing security vulnerabilities, you just run npm update and you’re done. With shadcn/ui? You have to manually merge upstream changes into your components.

This isn’t a huge deal for small projects, but for large projects where you’ve modified many components, merging upstream updates becomes a chore.

Also, shadcn/ui currently lacks those “advanced components” - DataGrid, Charts, complex date pickers. For those, you’ll need to find third-party libraries or build them yourself.

---

2. The Three Giants of Traditional Component Libraries

shadcn/ui is the new kid on the block, but let’s look at the “veterans” first.

2.1 Material-UI: The Enterprise Choice

Material-UI (now called MUI) came out in 2014, making it the oldest component library in the React ecosystem.

Its advantages are clear:

Unmatched component richness. DataGrid, Charts, Date Picker, TreeView, Autocomplete… basically any enterprise component you can think of, it has. I remember one project where MUI’s Pro components alone saved us about 2 months of development time.

Mature design system. Google’s Material Design specification, complete Figma files - designers and developers collaborate smoothly.

Rich ecosystem. Stack Overflow is full of MUI questions - you can basically find answers to any problem. Plus official templates, theme marketplace, abundant resources.

But the problems are also clear:

Large bundle size. 335KB core package - even if you only use a few components, the base package is still there. Tree-shaking helps, but doesn’t solve the root issue.

Customization difficulties. If your design differs significantly from Material Design, you’re in for a painful experience. I remember one project where the designer gave us designs that weren’t Material at all - we spent a week writing theme configurations and style overrides, the code piled up, maintenance got harder and harder.

Locked into Material style. Even if you change all the colors and fonts, that “Material feel” is hard to completely remove. Button ripple effects, card shadows, input animations… these details keep reminding users: this is Material Design.

// MUI's Button - you control it via variant and color props
<Button variant="contained" color="primary">
  Click Me
</Button>

// Want full customization? You have to do this
<Button
  sx={{
    background: 'linear-gradient(45deg, #FE6B8B 30%, #FF8E53 90%)',
    borderRadius: 3,
    border: 0,
    color: 'white',
    height: 48,
    padding: '0 30px',
    boxShadow: '0 3px 5px 2px rgba(255, 105, 135, .3)',
  }}
>
  Custom Button
</Button>

2.2 Chakra UI: King of Developer Experience

Chakra UI is a newer entrant, but the developer experience is genuinely excellent.

Its core philosophy: accessibility (a11y) is the default, not optional. Every component has built-in WAI-ARIA support, keyboard navigation, focus management, screen reader support - all out of the box.

Fast development. Chakra’s style props let you write styles like HTML attributes:

// Chakra UI approach - styles directly in props
<Box bg="tomato" p={4} borderRadius="md" boxShadow="lg">
  <Text fontSize="xl" fontWeight="bold" color="white">
    Hello World
  </Text>
</Box>

This approach makes prototyping incredibly fast - barely need to write CSS files.

Clean theming system. Define one theme configuration file, and your entire app’s colors, fonts, and spacing are unified. Dark mode is also one line of code.

But there are limitations:

React only. Using Vue or Svelte? Chakra is irrelevant to you.

Fewer components. Compared to MUI, Chakra’s component library is thinner. Especially those complex data display components - you’ll need third-party libraries.

Runtime styles. Chakra computes styles at runtime, which has some performance overhead. Most projects won’t feel it, but in scenarios with ultra-high-frequency updates (like real-time data dashboards), it could become a bottleneck.

2.3 Ant Design: The Standard for Chinese Enterprises

Ant Design comes from Alibaba and is widely used in China.

Complete enterprise components. Tables, forms, uploads, tree controls… covers almost all enterprise application scenarios. The Table component in particular is insanely powerful - sorting, filtering, pagination, fixed columns, virtual scrolling, everything.

Great internationalization support. Built-in support for over twenty languages, making multilingual projects convenient.

Friendly Chinese documentation. This is a huge advantage for Chinese teams. Official docs are detailed, tutorials are plentiful - when you run into issues, the Chinese community basically has answers.

But customizability is indeed weaker. Ant Design’s design language is strong - making it look like something else isn’t easy. Plus its styling system uses Less, while most projects have switched to Tailwind, making integration a bit awkward.

3. Seven Dimensions of Comparison

Talking about features isn’t enough - let’s look at concrete comparisons.

3.1 Bundle Size Comparison

Real-world data (using Bundlephobia and actual projects):

Component Library	Core Bundle	Actual Project Bundle
shadcn/ui	No core package, on-demand	150-200KB
Material-UI	335KB	300-400KB
Chakra UI	200KB	180-250KB
Ant Design	300KB+	280-350KB

Why is shadcn/ui so small?

1. No core package, only bundle components you use
2. No CSS-in-JS runtime
3. Tailwind styles are purged at build time, unused styles are deleted

For a medium-sized project, migrating from MUI to shadcn/ui, I’ve seen bundle sizes shrink 40-50% on average. This makes a real difference in mobile scenarios.

3.2 Customization Flexibility

This is shadcn/ui’s biggest advantage.

shadcn/ui: Source code is in your hands, change whatever you want. No “can I pass this prop?” or “how do I override this style?” questions. Just modify the component code directly.

MUI: Customize through theme and sx prop. Powerful, but always feels like “working around” things. Plus the theme system itself has a learning curve.

Chakra UI: Style props are flexible, but deep customization still has limitations. Some components have complex internal implementations that props alone can’t handle.

Ant Design: Weakest customizability. Theme variables exist, but what you can change is limited. Want a completely different visual style? Prepare to rewrite a lot of styles.

3.3 Developer Experience

Learning Curve:

• Chakra UI: Gentlest slope. Clear docs, clean API, basically ready after one read.
• MUI: Medium. Many components, many APIs, takes time to get familiar.
• Ant Design: Medium-steep. Complex component functionality, many configuration options.
• shadcn/ui: Steepest. You need to understand Radix primitives, be familiar with Tailwind, and get used to modifying component code directly.

Documentation Quality:

• MUI: Very detailed docs, many examples, complete API documentation.
• Chakra UI: Clean, clear docs with practical examples.
• Ant Design: Complete Chinese docs with design specifications.
• shadcn/ui: Docs are improving, but still thinner than the others.

Community Support:

• MUI: Largest community, most Stack Overflow questions, rich third-party resources.
• Ant Design: Active Chinese community, lots of Chinese resources.
• Chakra UI: Medium-sized community, but growing fast.
• shadcn/ui: New community, but fast-growing - GitHub Stars are approaching MUI already.

3.4 Accessibility

This is actually really important and shouldn’t be overlooked.

Chakra UI: Best accessibility work. Every component has built-in WAI-ARIA support, complete keyboard navigation, screen reader friendly. If your project has strict a11y requirements, Chakra is the first choice.

shadcn/ui: Based on Radix UI, accessibility is also excellent. Radix primitives are designed for a11y - ARIA attributes, focus management are all well done.

MUI: Accessibility is good too, most components comply with WAI-ARIA specs.

Ant Design: Medium level. Basic component accessibility is okay, but some complex components have incomplete keyboard navigation.

3.5 Component Richness

MUI: Most abundant. Basic components + advanced components (DataGrid, Charts, Date Picker, Tree View, etc.). The Pro components like x-grid and x-date-pickers are paid, but the functionality is truly powerful.

Ant Design: Very rich. Table, Form, Upload and other enterprise components are complete, basically enough.

Chakra UI: Medium. Has all basic components, but few advanced ones. If needed, you’ll have to find third-party libraries.

shadcn/ui: Least. Currently only has basic components (Button, Input, Dialog, Table, etc.), no DataGrid, Charts. The good news is the community is filling in the gaps - there are some extension libraries based on shadcn.

3.6 Long-term Maintainability

This needs to be looked at from two angles:

Automatic vs Manual Updates:

• MUI / Chakra / Ant Design: npm update gets you new features and bug fixes.
• shadcn/ui: Need to manually merge upstream updates.

Control vs Convenience:

• Traditional libraries: High convenience, limited control. Hit a bug or need customization? Wait for official fix or fork it yourself.
• shadcn/ui: Maximum control, but maintenance cost is on you. The upside is you can fix bugs yourself, don’t need to wait for official.

Migration Cost:

Migrating from one component library to another is never cheap. So choose carefully - once you pick one, you’re in it for the long haul.

3.7 Use Case Comparison

Scenario	Recommendation	Reason
Fully custom design system	shadcn/ui	Source code in hand, modify however you want
Enterprise admin dashboard	MUI or Ant Design	Rich components, works out of the box
Rapid prototyping / MVP	Chakra UI	Fast development, clear docs
Mobile / Performance-sensitive	shadcn/ui	Smallest bundle size
High accessibility requirements	Chakra UI or shadcn/ui	Built-in a11y support
Designer uses Figma	MUI	Has official Figma UI Kit

4. Selection Decision Framework

After all this, how do you actually choose? I’ve summarized a simple decision process.

4.1 Ask Yourself Three Questions

Question 1: How “unique” is your design?

• Design is completely custom, doesn’t look like any existing design system -> shadcn/ui
• Design is close to Material Design -> MUI
• Design is clean and modern, but doesn’t need heavy customization -> Chakra UI
• Design is enterprise-style, lots of tables and forms -> Ant Design

Question 2: How big is your project?

• Small project / MVP -> Chakra UI or shadcn/ui
• Medium to large enterprise application -> MUI or Ant Design
• Performance-sensitive (mobile, high traffic) -> shadcn/ui

Question 3: What is your team familiar with?

• Team knows Tailwind -> shadcn/ui is a natural fit
• Team knows Material Design -> MUI
• Team values development speed -> Chakra UI
• Team is in a Chinese enterprise -> Ant Design

4.2 My Personal Recommendations

For new projects:

My default choice now is shadcn/ui.

Reasons:

• Tailwind is already a standard, shadcn/ui fits perfectly
• Best performance, smallest bundle size
• Complete control, no “black box”
• Long-term maintenance is more manageable (code is in your hands)

Exceptions:

• If the project needs complex tables, charts, and the team doesn’t have time to find third-party libraries -> MUI
• If the project requires strict accessibility, and the team isn’t familiar with a11y -> Chakra UI
• If it’s a large Chinese enterprise project needing Chinese docs and local support -> Ant Design

For existing projects:

Migration cost is usually high. Unless there’s a clear reason (performance issues, customization difficulties, design system change), I don’t recommend switching. But if you do need to switch, shadcn/ui migration is relatively cheaper - because its components are independent, you can replace them one by one.

---

5. Migration in Practice: From MUI to shadcn/ui

If you decide to migrate, here’s some practical experience.

5.1 Migration Steps

Step 1: Audit Existing Components

List out which MUI components you’re currently using:

• Button, Input, Select and other basic components -> shadcn has all of these, replace directly
• DataGrid, Charts and other advanced components -> need third-party libraries or implement yourself

Step 2: Create Replacement Mapping

// Mapping table
const componentMap = {
  'Button': 'Button',          // Direct correspondence
  'TextField': 'Input',       // Different name, similar function
  'Dialog': 'Dialog',          // Direct correspondence
  'Select': 'Select',          // Direct correspondence
  'Table': 'Table',           // shadcn has basic Table, but no advanced features
  'DataGrid': '???'           // Need replacement (like TanStack Table)
}

Step 3: Replace One by One

Don’t switch everything at once. Start with one page, verify it works, then expand.

Step 4: Style Migration

MUI theme variables -> Tailwind configuration

sx prop -> Tailwind classes

// MUI approach
<Button sx={{ mt: 2, mb: 1, backgroundColor: 'primary.main' }}>
  Submit
</Button>

// shadcn/ui approach
<Button className="mt-8 mb-4 bg-primary">
  Submit
</Button>

5.2 Important Notes

1. Completely different style systems: MUI uses theme object + sx prop, shadcn uses Tailwind classes. During migration, you need to “translate” the styles.

2. Find replacements for advanced components: shadcn doesn’t have a ready-to-use DataGrid, I recommend TanStack Table. For Charts, you can use Recharts or Chart.js.

3. Animations may be lost: MUI’s ripple effects and transitions are built-in, shadcn needs you to add them yourself. You can use Tailwind’s transition and animate- classes.

4. Test! Test! Test!: After migration, make sure to test all interactions, especially forms and modals - those complex components.

5.3 Migration Cost Reference

My own experience:

• Small project (under 10 pages): 1-2 weeks
• Medium project (10-30 pages): 2-4 weeks
• Large project (30+ pages): 4-8 weeks, depending on advanced component complexity

---

6. Conclusion

After all this, I really just want to express one point:

There’s no best component library, only the one that’s best for you.

shadcn/ui’s emergence gives us a new choice: not “using a library,” but “owning the code.” For teams pursuing performance and customization, this is quite attractive.

MUI, Chakra UI, and Ant Design each have their strengths. MUI’s component richness and ecosystem maturity, Chakra’s developer experience and accessibility, Ant Design’s enterprise capabilities and localization support - these are all solid advantages.

The key to choosing: Know your needs, understand each library’s characteristics, and make the choice that fits your current project.

Finally, if you’re still undecided, I have a suggestion:

Try shadcn/ui.

Seriously, give it a try, and you’ll find it’s a completely different approach from traditional component libraries. That feeling of “the code is in my hands” is pretty satisfying.
