Introduction

PanelUI is a React Native component library for Expo apps. 26 typed components — bottom sheets, dialogs, selects, toasts, forms — styled with Tailwind CSS v4 and animated on the UI thread with Reanimated. It ships no native code, so it runs in Expo Go with no prebuild.

import { PanelUIProvider, Button, Card } from 'panelui-native';

export default function App() {
  return (
    <PanelUIProvider>
      <Card>
        <Card.Header>
          <Card.Title>Create project</Card.Title>
          <Card.Description>Deploy your new project in one click.</Card.Description>
        </Card.Header>
        <Card.Footer>
          <Button>Deploy</Button>
        </Card.Footer>
      </Card>
    </PanelUIProvider>
  );
}

Why PanelUI

• Tailwind CSS for React Native, via Uniwind — no Babel transform, and roughly 2.4–3× faster styling than NativeWind.
• 60fps animations on the UI thread with Reanimated 4. Press feedback, switches, sheets, dialogs and tabs never touch the JS thread.
• Six built-in themes across three families. A theme sets radius as well as colour, so switching one restyles the shape of the UI too.
• Native dark mode — theme changes are applied natively by Uniwind, without re-rendering your component tree.
• Accessible by default — every interactive component wires up accessibilityRole, mirrors its state through accessibilityState, and hides decorative icons from screen readers.
• TypeScript, tree-shakeable, zero native modules.

Design language

The token set comes from Coss UI — the same semantic names (background, primary, muted, destructive, …), translated for native. The component APIs follow the compound-component shape shadcn/ui popularised, so Card.Header and Dialog.Content behave the way you would expect.
