While I was writing scenario applications to test Google App Engine, I had the following idea: If BBEdit, Dreamweaver, CSSEdit, and TextMate were at a party, what kind of application would be welcomed to help with App Engine development? As silly as this sounds, it led me to think more about workflow. I used:
I began to think about how unfriendly command line interfaces can be, and how much repetitive typing I had been doing to test and deploy applications. With that said, I worked with John Grabowski of the Google Mac team and Brett Slatkin, an engineer on App Engine, on a 20% project to make Google App Engine Launcher for Mac OS X.
Now, App Engine Launcher is not a replacement for your code editor or your IDE. It improves your App Engine development experience by managing a list of your applications. With a few clicks you can run, browse, deploy, and view logs for your applications. It also has some added sugar thrown in like drag and drop, integration with your editor, and quick links to the local developer console and the live application dashboard.
