Flex is a highly productive, free open source framework for building and maintaining expressive web applications that deploy consistently on all major browsers, desktops, and operating systems. While Flex applications can be built using only the free Flex SDK, developers can use Adobe® Flex® Builder™ 3 software to dramatically accelerate development. Try Flex Builder 3 free for 60 days. Try ILOG Elixir to enhance data display in your Flex applications.
