Jumpstart your next React project with developer-friendly and user-friendly UI libraries: aesthetic, performance-optimized, and RSC-compatible.

Heading into 2025, selecting a React component library goes beyond aesthetics — you need libraries that meet rigorous standards for accessibility, internationalization, and performance.

In this post, we’ll explore 15 leading React component libraries that offer robust technology, ready-made templates, large community support, and performance-oriented features to help you deliver top-quality applications in the new year.

Before diving in, let’s take a look at a few concepts that have been around but are now more widely adopted across UI libraries.

Trends in UI component libraries

Zero Runtime CSS-in-JS: build-time CSS extraction of CSS-in-JS declarations. It retains most of the advantages of CSS-in-JS, like excellent developer experience, while eliminating its performance penalties. Perhaps more importantly, it offers support for React Server Components (RSC), which aren’t able to make use of runtime style-injection mechanisms like useContext or useState to manipulate CSS (since React lifecycle mechanisms are not available for them). These solutions often rely on WyW-in-JS (“whatever you want in JS”).
“Copy-Pasting” UI Components and “UI Blocks”: CLI tools for directly embedding the source code of UI components or UI component compositions into your project rather than installing npm packages. Shadcn UI is the most prominent player, but this can be seen in Chakra V3 as well. In addition to that, tools like Bit and Bit Platform have made every UI component, big or small, copy-able and are often used precisely for that.
Semantic tokens: These design tokens make styling and theming much more manageable by replacing “raw” or “primitive” values with an abstract layer that represents design intent, such as roles and UI elements. For example, you might use tokens like body.text.default.
CSS props (CSS variables): Instead of relying on library-specific styling solutions, CSS props allow for defining styles directly in CSS. This improves DevX as CSS props can be reviewed and manipulated from your browser’s dev tools. It also means there’s one less thing to learn about the library you’re using.

1. Material UI

Material UI is a comprehensive React component library that implements Google’s Material Design, providing accessible, responsive, and customizable components out of the box. It allows developers to quickly build production-ready UIs with advanced theming options, CSS utilities, and a strong design system. Material UI integrates seamlessly with popular frameworks and includes a suite of templates and design resources, making it a go-to choice for both rapid prototyping and scalable application development.

Technologies and optimizations

MUI uses a combination of runtime and build-time CSS-in-JS.

• Emotion: The default runtime CSS-in-JS solution.

• Pigment CSS: An optional zero-runtime CSS-in-JS engine designed for improved performance and React Server Component compatibility.

In addition to its new “zero runtime” support, which includes plugins and configurations for popular bundlers, MUI has been built for tree-shaking by implementing an incredibly modular design.

Theming and styling

Theming: Customize global themes using MUI’s theme provider to alter colors, typography, spacing, and more.
Styled Components: The styled API from Emotion creates custom themeable components
SX Prop: Apply styles directly to components using the sx prop with a concise syntax.
CSS variables (CSS props): Optional.

Internationalization and accessibility

RTL support: Automatically adjusts RTL language layout and component styling. This includes utility functions to manage RTL styling within custom components.
WCAG Compliance: Adheres to WCAG 2.1 guidelines to ensure content is perceivable, operable, understandable, and robust.
ARIA Attributes: Implements appropriate ARIA attributes in components.
Keyboard Navigation: Ensures all interactive components are accessible via keyboard.

Resources and tools from the community

Copy-able MUI components on Bit Platform

Probably the easiest way to start your own custom Material UI library is by copying this collection of Material UI components and themes from Bit Platform (using Bit’s CLI tool). This gives you the freedom to customize and extend individual MUI components and quickly create custom themes.

When you’re ready, share your components to your own collection on Bit Platform. From there, they can be installed in other projects as regular packages.

Radix Themes is a pre-styled sibling of the Radix Primitives library which is designed for rapid development with minimal configuration.

It offers a collection of accessible, customizable components that integrate seamlessly into modern web applications. You can quickly install Radix Themes, import the global CSS file, and wrap your application with the Theme component to start building immediately.

The library provides various customization options, including theming, color schemes, and layout components, allowing developers to tailor the appearance and behavior of components to meet specific project requirements.
