[HeroUI](https://heroui.com) pairs [React Aria](https://react-spectrum.adobe.com/react-aria/) accessibility with [Tailwind CSS v4](https://tailwindcss.com/) styling and a compound component API (`Card.Header`, `Table.Column`, `Modal.Body`). Components work with React 19 and the Next.js App Router out of the box.

**Key strengths:**

- **Accessibility-first architecture.** Every component is built on React Aria, Adobe's battle-tested accessibility primitives. This means screen reader support, keyboard navigation, and ARIA attributes are handled correctly out of the box — not bolted on as an afterthought.
- **Tailwind CSS v4 native.** HeroUI's styling system uses CSS-based theming with `@theme` and design tokens, avoiding the runtime overhead of CSS-in-JS.
- **Compound component API.** Components use a composable pattern (`Card.Header`, `Card.Content`, `Card.Footer`) that gives you full control over markup and layout without sacrificing ergonomics.
- **AI tooling.** HeroUI ships an [MCP server](/docs/react/getting-started/mcp-server), [llms.txt](/docs/react/getting-started/llms-txt), and [agent skills](/docs/react/getting-started/agent-skills) so AI coding assistants can look up current HeroUI APIs instead of relying only on training data.
- **Server component friendly.** Components are designed with React Server Components in mind — client boundaries are minimal and clearly documented.

**When to use it:** You want a modern, accessible component library with Tailwind CSS styling and first-class AI tooling support. Ideal for new projects using Next.js, React 19, and Tailwind v4.

## 2. shadcn/ui

[shadcn/ui](https://ui.shadcn.com/) isn't a traditional component library — it's a collection of copy-paste components built on Radix UI and Tailwind CSS. Instead of installing a package, you add component source code directly to your project.

**Key strengths:**

- **Full ownership.** Components live in your codebase, so you can modify them freely without fighting library abstractions or waiting for upstream changes.
- **Radix UI foundation.** The underlying primitives handle accessibility and complex interactions (popovers, comboboxes, dialogs) reliably.
- **CLI tooling.** The `shadcn` CLI scaffolds components into your project with the right dependencies and file structure.
- **AI-ready docs.** shadcn/ui publishes `llms.txt`, skills, and an MCP server for agents.
- **Massive ecosystem.** The community has built hundreds of extensions, themes, and integrations around shadcn's patterns.

**When to use it:** You want maximum control over component code and you're comfortable maintaining copied components. Works well for teams that need heavy customization.

**Trade-offs:** You own the code, which means you also own the bugs. Upstream fixes and improvements require manual re-integration. No central update mechanism. Additionally, shadcn/ui's foundation on Radix UI carries some uncertainty — the original Radix team has shifted focus to Base UI, and the long-term maintenance status of Radix primitives is an open question in the community.

---

## 3. Material UI (MUI)

[Material UI](https://mui.com/) is the most established React component library, with a decade of production use. MUI's stable styling path still centers on Emotion and the `sx` prop; Pigment CSS exists as an experimental zero-runtime direction rather than the default.

**Key strengths:**

- **Massive component count.** Over 70 components covering nearly every UI pattern you can think of, from basic buttons to complex data grids.
- **Material Design compliance.** If your design system is built on Material Design, MUI gives you pixel-perfect implementations.
- **Enterprise ecosystem.** MUI X offers premium components (data grid, date pickers, charts) with enterprise support and SLAs.
- **Mature and battle-tested.** Thousands of production apps run on MUI. Edge cases have been found and fixed over years.

**When to use it:** You're building a large enterprise application that needs Material Design compliance, or you need MUI X's premium data grid and date picker components.

**Trade-offs:** The Material Design aesthetic is opinionated. Theming away from Material's look-and-feel is possible but requires significant effort. Bundle size is larger than most alternatives.

---

## 4. Chakra UI

[Chakra UI](https://chakra-ui.com/) pioneered the "style props" pattern in React, letting you style components with props like `bg="blue.500"` and `p={4}`. Chakra's current theming docs describe a system built around the Panda CSS API with `defineConfig`, `createSystem`, recipes, slot recipes, tokens, and semantic tokens.

**Key strengths:**

- **Intuitive styling API.** Style props make it fast to prototype and iterate on designs without leaving your JSX.
- **Design token system.** The theme object gives you centralized control over colors, spacing, fonts, and breakpoints.
- **Good accessibility defaults.** Components follow WAI-ARIA patterns and include keyboard navigation.
- **Recipe-driven styling.** Chakra uses recipes, slot recipes, and a token-based system for component styling.
- **AI support.** Chakra documents an MCP server for AI-assisted workflows.

**When to use it:** You like styling through props rather than class names, and you want a cohesive design system with good defaults.

**Trade-offs:** The style props pattern can make JSX noisy for complex components. Migrating from v2 to v3 required significant changes because the component and theming APIs changed.

---

## 5. Mantine

[Mantine](https://mantine.dev/) is a full-featured React component library with a very broad component catalog, a hooks package, and a rich extension ecosystem. Mantine's homepage currently describes the library as `120+` components and `70+` hooks.

**Key strengths:**

- **Unmatched breadth.** Mantine has components and extensions for many product needs — date pickers, notifications, spotlight search, charts, forms, and more.
- **Large hooks package.** Beyond components, Mantine ships hooks for local storage, media queries, clipboard, idle detection, and many other common patterns.
- **CSS styling.** Mantine components are built with CSS files and can be customized through the Styles API.
- **AI tooling.** Mantine publishes LLM docs, skills, and an MCP server.
- **Form library.** `@mantine/form` provides form state management with validation that integrates seamlessly with Mantine inputs.

**When to use it:** You want a batteries-included library where you can find a component for almost any use case without adding third-party packages.

**Trade-offs:** The huge surface area means the bundle can grow quickly if you're not tree-shaking carefully. The component design aesthetic, while clean, is fairly specific.

---

## 6. Radix UI (Primitives)

[Radix UI](https://www.radix-ui.com/) provides unstyled, accessible UI primitives that you style yourself. It's the foundation behind shadcn/ui and many other component libraries.

**Key strengths:**

- **Accessibility gold standard.** Every primitive is built to WAI-ARIA specification with exhaustive keyboard navigation, focus management, and screen reader support.
- **Unstyled by default.** Zero design opinions means zero fighting with the library's aesthetic. Bring your own styling system.
- **Composable APIs.** Primitives use a compound component pattern with slot-based composition that gives you control over every rendered element.
- **Production-proven.** Radix primitives power thousands of production applications through both direct usage and shadcn/ui.

**When to use it:** You need accessible, behavior-only primitives and want complete control over styling. Great for teams building custom design systems.

**Trade-offs:** You need to bring all your own styling. The learning curve for the composition patterns can be steep for simpler use cases.

---

## 7. Ant Design

[Ant Design](https://ant.design/) is a comprehensive design system and component library created by Ant Group (Alibaba). It's especially popular in enterprise applications and the Chinese development community.

**Key strengths:**

- **Enterprise-grade components.** Complex components like Table (with sorting, filtering, pagination), Form (with validation), and Tree are mature and feature-rich.
- **Design system included.** Ant Design is a complete design system with design tokens, patterns, and guidelines — not just a component library.
- **Internationalization.** First-class i18n support with 60+ locale packages.
- **Component quality.** Each component handles dozens of edge cases that you'd otherwise need to build yourself.

**When to use it:** You're building a complex enterprise application, especially one that needs sophisticated data tables, forms, and tree views.

**Trade-offs:** The design aesthetic is distinctly "Ant Design" and theming it to look different requires substantial effort. Bundle size is significant. Accessibility support, while improving, still lags behind Radix/React Aria-based libraries.

## 8. Headless UI

[Headless UI](https://headlessui.com/) is a set of unstyled, accessible UI components from the Tailwind Labs team. It focuses on common interactive patterns — dropdowns, dialogs, tabs, comboboxes.

**Key strengths:**

- **Tailwind CSS integration.** Built by the Tailwind team, it works perfectly with Tailwind's utility classes and transition utilities.
- **Small, focused scope.** Only includes components that are genuinely hard to build accessibly (menus, listboxes, dialogs, etc.).
- **Lightweight.** Minimal bundle impact because of the focused component set.
- **Clean API.** Uses render props and compound components with a simple, predictable API.

**When to use it:** You're using Tailwind CSS and need a few accessible interactive components without a full UI library.

**Trade-offs:** Very small component set — you'll need other solutions for data tables, form inputs, date pickers, and most other patterns.

---

## 9. React Aria (Primitives)

[React Aria](https://react-spectrum.adobe.com/react-aria/) is Adobe's library of accessibility primitives for React. It provides hooks and components for building accessible UI from scratch.

**Key strengths:**

- **Industry-leading accessibility.** React Aria is arguably the most thoroughly accessible UI primitive library available. It handles internationalization, right-to-left layouts, touch interactions, and edge cases that most libraries miss.
- **Hooks + components.** Offers both low-level hooks (for maximum flexibility) and higher-level components (for convenience).
- **Platform-aware.** Adapts behavior based on device type, pointer type, and platform conventions.
- **Foundation for other libraries.** HeroUI, Adobe Spectrum, and other libraries build on React Aria, proving its reliability at scale.

**When to use it:** You're building a design system from scratch and need the strongest possible accessibility foundation. Also useful when you need specific primitives (like a color picker or calendar) that other libraries don't offer.

**Trade-offs:** Steeper learning curve than styled libraries. You need to bring all your own styling and composition patterns.

---

## 10. Ark UI

[Ark UI](https://ark-ui.com/) is a headless component library from the creators of Chakra UI, built on top of state machines for predictable behavior.

**Key strengths:**

- **State machine architecture.** Uses Zag.js state machines under the hood, making component behavior predictable and debuggable.
- **Framework-agnostic core.** The same state machines power React, Vue, and Solid versions of every component.
- **Modern patterns.** Includes components like Signature Pad, Pin Input, and Splitter that aren't commonly found in other headless libraries.
- **Styling flexibility.** Works with any styling solution — Tailwind, Panda CSS, vanilla CSS, CSS modules.

**When to use it:** You want headless components with predictable state management, or you need to share component logic across React, Vue, and Solid projects.

**Trade-offs:** Smaller community than Radix or React Aria. The state machine abstraction adds conceptual overhead for simple components.

---

## 11. Tremor

[Tremor](https://tremor.so/) is focused on dashboards and data visualization. Its current docs describe Tremor Raw as designed for React 18.2+ and Tailwind CSS 4.0+.

**Key strengths:**

- **Dashboard-first design.** Purpose-built resources for analytics, dashboard UI, and data display.
- **Tailwind native.** Integrates seamlessly with existing Tailwind projects without additional styling configuration.
- **Clean defaults.** Charts and metrics look polished out of the box with a cohesive design language.
- **Lightweight scope.** Focused on data display, so you pick what you need without pulling in an entire UI framework.

**When to use it:** You're building analytics dashboards or data-heavy interfaces and already use Tailwind CSS.

**Trade-offs:** Limited to dashboard-specific components. You'll need another library for general UI patterns like forms, navigation, and dialogs.

---

## 12. Park UI

[Park UI](https://park-ui.com/) is a styled component library built on Ark UI primitives, available in both Panda CSS and Tailwind CSS variants.

**Key strengths:**

- **Pre-styled Ark UI.** Takes Ark UI's headless components and adds polished, customizable styling — similar to what shadcn/ui does for Radix.
- **Dual styling support.** Available in both Panda CSS and Tailwind CSS variants, so you can pick the approach that fits your project.
- **Copy-paste model.** Like shadcn/ui, components are added to your project as source files you own and customize.
- **Design tokens.** Ships with a token system that makes global style changes straightforward.

**When to use it:** You like the shadcn/ui copy-paste model but prefer Ark UI's state-machine-based primitives over Radix, or you're using Panda CSS.

**Trade-offs:** Smaller community and ecosystem compared to shadcn/ui. Fewer third-party extensions and themes.
