Technology Comparisons

Note: The current release is Flex 4. This page is for Flex 3. To get started with Flex 4 and Flash Builder 4 (formerly known as Flex Builder), see the Getting Started page on the Flex Developer Center.

When integrating Flex 3 with other technologies, the most important points to remember are:

• Flex is a client-side technology that is rendered by Flash Player 9 or Adobe AIR.
• Flex can work with JavaScript on the client.
• Flex requires a server-side technology (like ColdFusion, LiveCycle Data Services, Java, ASP.NET or PHP) to provide it with real-time data.
