Things people build with this

USE CASE 1

Build a mobile app with consistent buttons, forms, and modals across iOS and Android without designing each component.

USE CASE 2

Create a web app that shares the same UI component library as your React Native mobile app for brand consistency.

USE CASE 3

Set up a design system with centralized theming so color, font, and spacing changes apply to all components automatically.

USE CASE 4

Ensure your app is accessible to screen reader users by leveraging built-in ARIA patterns in every component.

In plain English

NativeBase is a component library for React Native and the web, built to help developers create consistent user interfaces across Android, iOS, and web browsers without having to build everything from scratch. It provides roughly 40 pre-built UI components, buttons, forms, checkboxes, badges, alerts, modals, navigation elements, and more, that behave and look consistently no matter which platform they run on. The library was designed with accessibility baked in from the start, using standard ARIA patterns so that screen readers and other assistive technologies work out of the box. It also supports theming, meaning you can define your app's colors, fonts, and spacing once and have every component follow those rules automatically, including a built-in dark mode. Responsiveness is handled through a utility-props system (inspired by tools like TailwindCSS), where instead of writing separate style rules for different screen sizes you pass in an object with values for each breakpoint. NativeBase runs on top of React Native and Expo, and web support is provided via React Native Web. The maintainers have noted that the project is now deprecated and has evolved into a successor library called gluestack-ui, which they recommend for new projects. For existing projects using NativeBase, or teams evaluating it for historical context, it is most relevant to developers building cross-platform React Native apps who want a production-ready UI component foundation without designing every element themselves.
