AppJet, Inc. [1] 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. [2] 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. [3] 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. [4]
On August 14, 2008, AppJet released a programming tutorial aimed at a target audience of "absolute beginners". [5]
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.
"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.
A major update to the site was a graphical change implemented on July 10, 2008. [11]
Appjet.ai launched on August 27, 2025 as an independent, AI powered version of the original product [12] [13]
