AppJet was a website that let users create web based applications in a client web browser, with no other client software. AppJet was founded by 3 MIT graduates, 2 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.
On August 14, 2008, AppJet released a programming tutorial aimed at "absolute beginners". The tutorial used the AppJet IDE to provide a programming sandbox for examples, 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.
Appjet is often updated with bug-fixes, improvements, and other features. A major update to the site was a graphical change implemented on July 10, 2008. This update also added the feature to "Comment" on users apps. Comments are messages about apps left at the URL comments.appname.appjet.net.
Another update occurred on May 2, 2008. This update lets apps be hosted at custom domains
