If you have not heard about Railo, then you should. It is an excellent CFML engine and best of all, the pricing on it is awesome. ColdBox is fully supported under the new Railo 2.0 and let me tell you, it FLIES!! Railo on itself is an incredibly fast CFML engine. You add ColdBox to the mix and you have a powerful combination. You can go here and find out more information about Railo & ColdBox.

ColdBox can also be converted into a Railo archive and all the new upcoming releases will include the framework in Railo Archive format. So if you haven't checked out Railo, then do, it is a great CFML alternative.
