AppJet

AppJet, Inc. was a website that allowed users to create web-based applications on a client web browser. AppJet was founded by three MIT graduates, two of whom were engineers at Google, before starting AppJet. They launched their initial public beta on December 12, 2007, allowing anyone to create a web app.

AppJet received funding from Y Combinator in the summer of 2007. However, the project was closed on July 1, 2009 to focus on other businesses. AppJet was finally acquired by Google on December 4, 2009, for an undisclosed amount.

Programming tutorial
On August 14, 2008, AppJet released a programming tutorial aimed at a target audience of "absolute beginners".

The tutorial used the AppJet IDE to provide a programming sandbox, allowing readers to experiment with sample code. This was one of the first online tutorials to embed an IDE, exposing a complete server-side web app framework inline with text.

Web software framework
"AppJet" refers to both the web application development platform and the server-side JavaScript framework that powers AppJet applications. This framework enables developers to code entire web applications using only one language, instead of having to use separate languages for server-side and client-side scripting.
