OpenFL is an open-source framework designed for building cross-platform applications and games. It allows developers to write code in Haxe, a high-level programming language, and then deploy it on various platforms, including HTML5, iOS, and Android. This flexibility makes it easier to create applications that can run on multiple devices without needing extensive modifications. The framework is inspired by Adobe Flash, providing a familiar environment for developers who have experience with Flash development. With its rich set of features, including support for graphics, sound, and user input, OpenFL simplifies the process of creating interactive content while maintaining high performance across different platforms.
