Among the libraries that do span both, there's a real philosophical split. Native-first libraries start from React Native's model and reach the web through react-native-web, which gives excellent mobile fidelity but a web experience that can feel like a port. Universal libraries start from a platform-agnostic layer and compile to each target, which keeps the web first-class but ties you to that library's compiler and styling conventions. Neither is wrong; they optimise for different ends of the same spectrum.
The decisive factors are therefore about coherence and lock-in: does the same component API behave the same on both platforms so your team isn't relearning per target, and is the theming genuinely shared so a brand change doesn't have to be made twice? A token system that both platforms read from is the cleanest answer to both, because it sidesteps the question of whose styling model wins by expressing design in values neither platform owns.
What actually matters
- Genuine first-class support for both web and React Native, not a web-only library you discover too late can't ship to mobile.
- Theming and tokens shared across platforms, so a palette or spacing change is made once rather than maintained separately per target.
- Consistent component APIs across web and native, so the team doesn't relearn props and behaviour per platform.
- Accessibility that holds on both platforms, since web ARIA and native accessibility APIs are entirely different surfaces to get right.
Recommendations
Tamagui
The most mature universal option for true React Native + web: an optimizing compiler flattens styles for web performance, with a powerful typed theming system shared across both. The cost is real lock-in to its compiler and styling conventions, and a steeper learning curve than most libraries. Compare Vireya vs Tamagui.
gluestack-ui
Universal copy-paste components styled with NativeWind, so teams already fluent in Tailwind get familiar DX across both platforms with real React Native components. You own and maintain the copied source, and you're committing to the NativeWind toolchain on native. Compare Vireya vs gluestack-ui.
React Native Paper
A mature Material Design 3 library that's excellent if mobile is your primary target. Its web support comes via react-native-web, so the web experience is more a capable port than a first-class web UI, and you're adopting Material Design. Compare Vireya vs React Native Paper.
Vireya
Vireya takes a different route to mobile and is worth knowing here precisely because it isn't a React Native library. Instead of rebuilding your UI in native components, you build it once as a web app and ship it inside a native WebView shell with a typed bridge — one codebase reaching web and mobile (see the hybrid approach). Choose it if you'd rather not maintain a separate React Native UI; choose a true-RN library above if maximum nativeness is the goal.
The bottom line
There are really two answers here, because there are two routes to mobile. If you want true React Native — your UI rendered as native components — Tamagui leads for proven universal apps, gluestack-ui suits Tailwind teams, and React Native Paper is the safe, mature pick when mobile leads and Material fits. If you'd rather not build a second UI in React Native at all, Vireya's hybrid route ships one web codebase inside a native WebView with a typed bridge. Pick by whether you value raw nativeness (true RN) or a single codebase and web velocity (hybrid).

Frequently asked questions
What is the best React UI library for React Native and web?
For true React Native rendered as native components, Tamagui is the most proven universal option, gluestack-ui suits Tailwind teams, and React Native Paper leads when mobile is the priority. Vireya is a different route — a hybrid WebView approach that ships one web codebase to mobile rather than rebuilding it in React Native.
Can I use the same components on web and React Native?
With universal RN libraries, yes — Tamagui and gluestack-ui render real React Native components on native and reach the web too. Vireya works differently: it doesn't render React Native components; it runs your web UI inside a native WebView, so the 'same components' run as web in a native shell rather than as native views.
Is hybrid WebView or true React Native better?
Neither is universally better. True React Native (Tamagui, gluestack-ui, React Native Paper) maximises nativeness at the cost of a second UI codebase and toolchain. Hybrid WebView (Vireya) keeps one web codebase and updates dynamic screens without app-store review, trading some nativeness for velocity. Content- and commerce-heavy apps often favour hybrid; deeply native or animation-heavy apps favour true RN.
