Flex is a highly productive, open source application framework for building and maintaining expressive web applications that deploy consistently on all major browsers, desktops, and devices. It provides a modern, standards-based language and programming model that supports common design patterns suitable for developers from many backgrounds.
Get involved with an active open source project. Flex is now being developed at the Apache Software Foundation so you can participate in the project and directly contribute to the next version of the framework.
Use constructs like strong typing, inheritance, and interfaces to program more efficiently. Extensive mobile and traditional components help speed development. Flex applications can access device capabilities such as GPS, accelerometer, camera, and local database.
Create applications that run consistently across Android™, BlackBerry® Tablet OS, and iOS devices, as well as inside the browser and on traditional desktop computers. Although cross platform, with Flex you get an uncompromised native experience on each platform.
Build Flex applications more easily using Adobe® Flash® Builder® software, an enterprise-class Eclipse™ based IDE. Productivity features include on-device debugging and mobile simulators for testing across screen sizes and resolutions.
