PureMVC is a lightweight framework for creating applications in ActionScript 3, based upon the classic Model-View-Controller design meta-pattern. This free, open source framework does not depend on any Flash, Flex or Apollo classes, and is therefore suitable for architecting applications on any platform running AS3.

ActionScript 3 is a strongly-typed, fully object-oriented language based on the same standard as JavaScript (ECMAScript), though AS3 implements a more current edition (Edition 4). It is the internal scripting language for Adobe Flash, Flex, and Apollo, and is currently being integrated into the FireFox browser by the Mozilla Foundation as the next generation of JavaScript.
