Silverlight Spy, FireBug type tool for Flex

Question

Is there a debugging tool for Flex that functions like Silverlight spy or FireBug?

Answer 1

Checkout flexbug, its built on fxspy. I'm sure how well supported it is, but its open source so if you don't like something... change it :)

For remote objects, http services, web services etc. I like charles.

Answer 2

De MonsterDebugger. It has an AIR app that acts like firebug, let you inspect/change variables, call public methods at runtime, etc. It is not Flex only, instead, you can use it in any as3 project.

reflexutil is for flex. But I haven't used it.

Also, I found the list of helpful Flex or Flash debug tools.
