Cross-Platform Development Framework

A software development toolkit that allows developers to write application code once and deploy it on multiple operating systems, such as iOS and Android. Popular examples include React Native, Xamarin, and Flutter. While CPDFs reduce development and maintenance costs, research has shown they have significant gaps in accessibility support — particularly for screen reader APIs. Many native accessibility features are not wrapped by CPDFs, forcing developers to write platform-specific code to achieve full accessibility, which partially negates the write-once advantage.
