AppScale is the world’s most popular open source PaaS. AppScale implements Google App Engine in Open Source, meaning you have the same benefits of the brilliant App Engine development model without being locked-in to Google. You now have the flexibility to run your GAE application on any public or private cloud, including on-premise. AppScale provides “freedom for your application.” You still retain the agile App Engine model to quickly develop and launch your application, but now you have the freedom to choose which public cloud to use. Easy. Fast. AppScale.

AppScale is developed and maintained by AppScale Systems, Inc., based in San Francisco and Santa Barbara, California.



AppScale began as a research project at the "University of California, Santa Barbara Computer Science Department under the supervision of Professor Chandra Krintz.[3] The project was originally funded by the "NSF, with additional funding from "Google, "IBM and "NIH. In 2012, co-founders Dr. Chandra Krintz, Chief Scientist, Dr. Navraj Chohan, Development Lead, and Woody Rollins, CEO founded AppScale Systems to commercialize the private PaaS AppScale technology.

In 2014, Graziano Obertelli joined AppScale as VP of Operations from Eucalyptus Systems, where he was a co-founder.
