RN Custom Alert and Prompt is an open-source React Native library that includes customizable Alert and Prompt components with no third-party dependencies. The library offers the flexibility to display alerts with either Android or iOS style, allowing developers to provide platform-specific consistency or show a general alert across both platforms.

Developers can choose how to implement these alerts based on their app’s requirements. Additionally, the library supports both light and dark themes, with platform-specific variations to ensure a seamless user experience on different operating systems.
