ActionScript 3.0 UML and Code Generation Tools

If you are interested in generating UML and/or AS3 code you might want to take a look at the following tools. The price tags range from $0 to $239.

Cairngen - Free

This tool provides AS3 code generation for Cairngorm based Flex projects. You’ll need to have Ant installed and know how to run and modify Ant scripts so there is a barrier of entry here. It would be great if Cairngen had a GUI.

VASGen - Free

There are a few issues with VASGen, like no package name support, but the AS3 code generation is pretty good. This tool is definitely worth checking out, especially considering the price. If you aren’t planning on using Cairngorm and you want a free tool this might be the solution.

UMLet - Free

This app can be set up as a Flex/Eclipse plug in. Pretty cool, no code generation from what I could tell though.

Enterprise Architect - $239-$135

At one point I had a trial copy of EA that was generating AS3, if memory serves me it did take a few hours of changing settings and research to get the code gen working though. Unfortunately the current price tag is out of my reach so no further information is available.

Visual Paradigm - $70-$59

Visual Paradigm claims AS3 generation but I’ve seen some concerns, and have my own (that doesn’t look like AS3 to me, notice the lack of a package?).
