 ## Why choose `react-native-error-boundary` over [`react-error-boundary`](https://github.com/bvaughn/react-error-boundary)?

It provides a default `FallbackComponent` that uses React Native components underneath, so this is **not compatible with React** on the web. Additionally, the API for `react-error-boundary` is somewhat different, having many more options than `react-native-error-boundary` while also seemingly being compatible with React Native.
