For iOS and Android apps built with React Native, the best component library depends on your design system, need for platform-native controls, and whether you also ship for the web. React web component libraries do not automatically target native iOS and Android. Start with React Native’s built-in components if they meet your needs; add a library when its design system or platform capabilities solve a specific problem.
Quick picks by project need
| Choose | Best fit | What to know |
|---|---|---|
| React Native built-in components | Distinctive design systems, platform-specific behavior, or fewer dependencies | Core components cover common interface needs; add community libraries for specialized features. React Native’s component and API documentation lists the available building blocks. |
| React Native Paper | Teams happy to use Material Design as their visual foundation | Offers themed components and says it supports Material You, accessibility features, RTL, and web and mobile. See Paper’s documentation. |
| Tamagui | Shared React Native and React web styling or a typed design system | Offers styled and unstyled components. Compiler and performance advantages are project-reported claims, not a neutral head-to-head benchmark. See Tamagui’s documentation. |
| Expo UI | Apps that need platform-native SwiftUI or Jetpack Compose controls | A primitives layer, not an opinionated design kit; platform-specific APIs differ, alongside universal components. See Expo UI’s documentation. |
| React Native Elements (RNEUI) | A general component toolkit with React Native Web support | The repository documents @rneui/themed and @rneui/base; confirm current releases and compatibility for your stack. See the RNEUI repository. |
| gluestack-ui | Teams evaluating the current direction of the NativeBase project | NativeBase’s documentation recommends gluestack-ui for new projects. Check migration and support requirements before choosing either. See the NativeBase site. |
First decide whether you need a library
React Native includes common building blocks such as View, Text, Image, TextInput, Pressable, Button, and list components. If those cover the app’s interactions and your team can implement its own visual system, using them directly avoids adopting a broader UI dependency. The official components and APIs reference points to community libraries for more specialized needs.
A library is most useful when it supplies a coherent design language, reusable styling conventions, or controls that would otherwise take substantial work to build. Decide what you need before comparing feature lists: a Material-based app has a different shortlist from one that must share styling with a web product or use platform-native controls.
Compare libraries by the constraint that matters most
React Native Paper: a Material foundation
Paper is a practical starting point when Material Design is an acceptable fit rather than a visual direction you would need to undo. Its project documentation describes Material You support, theming, accessibility features, right-to-left language support, and web and mobile coverage (React Native Paper documentation). Those are project claims, not the result of an independent accessibility audit. Check the components and customization options against your own design requirements.

Tamagui: a shared mobile and web styling system
Consider Tamagui if the product needs shared React Native and React web styling or a typed design system. Its documentation offers styled and unstyled components and describes compiler optimizations and performance benefits (Tamagui documentation). Treat those optimization benefits as vendor-reported capabilities: there is no same-app, same-device comparison here establishing that Tamagui is faster or smaller than the alternatives. Measure your own app if those outcomes determine the choice.
Expo UI: platform-native primitives
Expo describes Expo UI as “not ‘yet another’ UI library and not an opinionated design kit” (Expo UI documentation). Its distinction is that it exposes native UI primitives, including SwiftUI views on Apple platforms and Jetpack Compose components on Android, rather than imposing one cross-platform visual system. It also provides universal components for Android, iOS, and web; the platform-specific APIs are not identical. Treat it as a primitives layer and prototype the controls you need on each target platform before committing.

React Native Elements: a general toolkit with web support
RNEUI is worth evaluating if you want a general-purpose toolkit and React Native Web support. Its repository currently documents installation through @rneui/themed and @rneui/base (RNEUI repository). Because compatibility and release status can change, confirm that its current packages support your React Native and web setup before building around them.
NativeBase and gluestack-ui: account for the project transition
Do not treat NativeBase as the default greenfield choice without considering the project’s stated direction. NativeBase’s official documentation recommends gluestack-ui for new projects, and its site says “NativeBase is now gluestack” (NativeBase site). If you are maintaining an existing NativeBase app, assess its current support needs separately; if starting fresh, examine gluestack-ui’s migration and compatibility guidance for the APIs you expect to use.

How to choose for your app
- Write down your non-negotiables. Specify the platforms you ship, whether web shares UI code, the required design system, and any controls that must behave like platform-native UI.
- Remove mismatches. If you need an opinionated Material foundation, assess Paper. If shared mobile/web styling is central, compare Tamagui and RNEUI. If native SwiftUI or Compose controls matter, prototype Expo UI. If none of those needs applies, begin with React Native’s built-ins.
- Check the actual components. Build a small representative screen using the controls, themes, layout patterns, and accessibility behavior your product requires. A library’s general feature list does not guarantee that its components fit your design.
- Test on every target platform. Pay particular attention to platform-specific APIs, web behavior, and any native dependencies. Expo UI explicitly distinguishes platform-specific from universal components, so shared code should not be assumed to mean identical APIs.
- Verify project health and compatibility. Review current release and platform support information, especially for RNEUI and the NativeBase-to-gluestack direction. Confirm the chosen packages work with the app’s React Native, Expo, and web configuration.
- Measure only what matters. If performance or bundle size is a deciding factor, compare the finalists in the same app and build conditions. The cited project material does not establish a neutral ranking for speed, size, accessibility, or maintenance.
What “best” means in practice
There is no universal winner established by comparable testing. Paper is the most direct fit when Material Design is the desired foundation; Expo UI is distinct when native SwiftUI or Compose primitives are the requirement; Tamagui is relevant when shared mobile/web styling is central. React Native’s built-ins remain a sound option for teams that want to own their design system, while RNEUI and gluestack-ui merit evaluation when their toolkit approach matches the app.
