Using the Flex profiler with a Flash Website or Application

Ted Patrick posted on is blog a video of a presentation that was made at 360 Flex about the Flex Builder 3 Profiler by Jun Heider. It’s a pretty interesting talk about some unknown feature and tweaks of the profiler. One of the thing I learned that I am really happy to have found was the fact that you can use the profiler on a project that wasn’t made using the Flex Builder,¬† for example a project made in the Flash IDE. Here are the three simple steps you have to do.


  • Go to the Profiler view and in the Profile menu select “Profile External Application”
  • In the window that will prompt, select the radio button Launch the application manually outside Flex Builder

In Flash

  • All you have to do in Flash is to run the debug version of your movie (“Debug Movie” in the Debug menu)

That’s it, the Profiler will kick in for your Flash application.

Now I don’t see any reasons to use Flex anymore.

    Thank you for this! I have wanted to do this for a long time now but never knew it was possible.

    Did you ever try the Open Source alternative?
    Try FlashPreloadProfiler:
