Flex is a free, open-source framework for building and maintaining expressive web applications that deploy consistently on all major browsers, desktops, and operating systems. Flex is licensed under the open-source MPL license.

Adobe Flex Builder™ is an Eclipse™ based development tool that accelerates Flex development and includes capabilities for deploying RIAs on Adobe AIR.

To add even more functionality to your Flex web applications, try Adobe AIR™. Adobe AIR software lets you extend your RIAs to the desktop easily and quickly, using your existing tools and skills.
