Is shadcn/ui free to use?

Yes, shadcn/ui is fully open source and free for commercial use. Because you copy components into your project, there is no license, no dependency, and no subscription required. You are free to modify, reuse, and distribute the code in commercial projects without any restrictions whatsoever. This is a significant advantage over Material UI's paid Pro components for enterprise features.

Can I use shadcn/ui without Tailwind CSS?

No, shadcn/ui is specifically designed for and inseparably connected to Tailwind CSS. All components use Tailwind utility classes for styling and the configuration is based on Tailwind's design tokens. If you prefer a different CSS approach such as CSS-in-JS or CSS Modules, Material UI with Emotion or Styled-components is a better alternative for your project.

Which has a smaller bundle size?

shadcn/ui is significantly lighter because you only include the components you actually use and no runtime CSS-in-JS engine is required. Material UI includes more code by default due to the Emotion runtime and Material Design stylesheets, even with tree-shaking enabled. For performance-critical applications, shadcn/ui typically results in a significantly smaller final bundle size.

Can I migrate from Material UI to shadcn/ui?

Yes, but it requires considerable effort. The component APIs are different, the styling approach is fundamentally different with Tailwind versus CSS-in-JS, and not all MUI components have a shadcn/ui counterpart. We recommend migrating component by component rather than all at once, starting with simple components like buttons, inputs, and cards before tackling more complex widgets.

Which library is better for a design system?

shadcn/ui is better suited for building a custom design system because you own the source code and can customize every visual aspect to your brand guidelines. Material UI is better if you want to use the Material Design system as a foundation and build upon it via the theme object. The choice depends on how much you want to deviate from an existing design system.

shadcn/ui or MUI for your React app? We rebuilt the same dashboard in both. Final bundle size, time-to-customize, accessibility scores and total cost of ownership measured. Clear pick per project type.

shadcn/ui and Material UI represent two fundamentally different philosophies for component libraries. shadcn/ui gives maximum control and flexibility by placing components as source code in your codebase, making it ideal for custom designs with Tailwind CSS and projects where brand identity is crucial. Material UI offers the most complete package of production-ready components with a proven design system, advanced DataGrid and DatePicker components, and an extensive theme system. Choose shadcn/ui when you want to build a unique design without restrictions. Choose Material UI when you need a consistent, professional interface quickly with advanced enterprise components that are complex to build yourself.

shadcn/ui vs Material UI (2026): Which Should You Pick?

Background

The choice between shadcn/ui and Material UI reflects a broader trend in the React world: the shift from traditional npm-installed component libraries toward a copy-paste model where developers own the source code. shadcn/ui, created by shadcn, has accelerated this trend by making high-quality Radix UI-based components available that you copy into your project and fully customize. Material UI remains the most downloaded React component library with millions of monthly npm installations. Both approaches have clear advantages and the right answer depends on your priorities: maximum control or maximum component offering.

shadcn/ui

Not a traditional component library but a collection of reusable components you copy into your own project. shadcn/ui is built on Radix UI primitives for accessibility and styled with Tailwind CSS for maximum flexibility. Because the source code lives in your project, you have full control over styling, behavior, and customizations. There is no vendor lock-in, no external dependency to track, and no abstraction layer limiting you. In 2026, shadcn/ui has more than 40 components and a growing ecosystem of community extensions and themes.

Material UI

The most popular React component library in the world, based on Google's Material Design system. Material UI (MUI) version 6 provides an extensive set of more than 50 production-ready components, a powerful theme system with CSS variables, and support for both Material Design and fully custom design systems via MUI System. MUI also offers paid components such as DataGrid Pro and DatePicker Pro for enterprise applications with advanced data display and manipulation capabilities.

What are the key differences between shadcn/ui and Material UI?

Feature	shadcn/ui	Material UI
Distribution model	Copy-paste where components live in your own codebase and you fully own them	NPM package installed as a dependency with automatic updates via your package manager
Styling	Tailwind CSS utility-first with full customizability via classnames and CSS variables	Emotion or Styled-components as runtime CSS-in-JS, with Tailwind option via MUI System
Customizability	Complete because you own the source code and can modify everything directly without limits	Via theme object and sx prop, but the underlying component structure is determined by MUI
Component offering	Growing with more than 40 components and active community extensions increasing every week	Very extensive with 50+ components including complex DataGrid, DatePicker, and TreeView widgets
Bundle size	Minimal because only used components are included without any extra runtime overhead at all	Larger due to Emotion runtime, Material Design CSS, and extra abstraction layers that ship
Accessibility	Excellent thanks to Radix UI primitives specifically designed for complete WAI-ARIA compliance	Good with Material Design guidelines that follow accessibility standards but offer less granular control
Design flexibility	Unlimited because you modify the full source code and can change every visual aspect freely	Limited to theme variables and sx prop, deviating from Material Design requires more effort
Maintenance	You manage updates yourself, giving more control but also more responsibility for changes	Updates via npm with changelogs and migration guides, less control but less maintenance work

When to choose which?

Choose shadcn/ui when...

Choose shadcn/ui when you want full control over every component without abstraction layers or vendor lock-in. shadcn/ui is ideal for projects with Tailwind CSS, custom design systems, and situations where you want to precisely tune the appearance of every button, input, and dialog to your brand identity. The combination with Radix UI primitives guarantees excellent accessibility as a foundation. The smaller bundle size without runtime CSS-in-JS is a bonus for performance.

Choose Material UI when...

Choose Material UI when you need a professional interface quickly with a consistent, recognizable design and advanced components out of the box. Material UI offers the broadest component selection with DataGrid Pro, DatePicker, TreeView, and Autocomplete that are complex and time-consuming to build yourself. It is ideal for admin dashboards, internal tools, and enterprise applications where the Material Design aesthetic fits and development speed is the priority.

What is the verdict on shadcn/ui vs Material UI?

Which option does MG Software recommend?

At MG Software, shadcn/ui is our default component library for all new projects. The combination with Tailwind CSS 3.4 and Radix UI primitives gives us full control over the design while benefiting from accessible, tested components as a solid foundation. We appreciate Material UI specifically for admin dashboards and internal tools where the rich component offering, particularly the DataGrid and DatePicker, saves significant development time. For customer-facing products where brand identity and visual differentiation are crucial, we always recommend shadcn/ui for its boundless customizability and absence of vendor lock-in.

Migrating: what to consider?

Migrating from Material UI to shadcn/ui requires replacing MUI components with their shadcn/ui equivalents and converting theme configuration to Tailwind CSS classes. Not all MUI components have direct counterparts in shadcn/ui, particularly the DataGrid and DatePicker require custom solutions or alternative libraries. Budget three to eight weeks depending on the number of components. The reverse migration from shadcn/ui to Material UI is simpler but requires giving up your custom styling in favor of the MUI theme system.

Frequently asked questions

shadcn/ui has a clear advantage thanks to its use of Radix UI primitives, which are specifically designed for complete WAI-ARIA compliance with keyboard navigation and screenreader support. Material UI also follows accessibility standards via Material Design guidelines, but Radix UI primitives are considered in the industry to be the most robust and thoroughly tested accessibility primitives for React.

shadcn/ui offers a basic Table component and a DataTable built on TanStack Table for sorting, filtering, and pagination. This is less comprehensive than Material UI's DataGrid Pro which offers enterprise features such as virtualization, column grouping, and inline editing. For complex data-intensive applications, Material UI's DataGrid provides more out-of-the-box functionality without building it yourself.
