Looks like we missed it, but back in December of 2011, Google officially stopped developing App Inventor (it was a result of the company’s shutdown of Google Labs), allowing MIT to take the reins of a very similar project. Today, that project went open source, and though there’s very little in the way of documentation or guides, you can download the code now and begin modifying the Inventor.

Additionally, MIT hasn’t yet opened its servers, so you’ll have to find your own place to upload your modified version(s) of the file – but hey, if nothing else, at least MIT deems you “free to use the term ‘App Inventor’ and the puzzle-piece Android logo” in your work. The code will be updated “periodically”; for a look at what’s out there now, hit up the source link.
