Developer tools and open-source projects

App Engine

lets developers run web applications on Google Cloud. Google App Engine supports apps written in several programming languages. With App Engine's Java runtime environment, one can build their app using standard Java technologies, including the JVM, Java servlets, and the Java programming language—or any other language using a JVM-based interpreter or compiler, such as JavaScript or Ruby. App Engine also features a dedicated Python runtime environment, which includes a fast Python interpreter and the Python standard library.

, on the client system to cache data locally. Gears-enabled pages used data from this local cache rather than from the online service. Using Gears, a web application may periodically synchronize the data in the local cache with the online service. If a network connection is not available, the synchronization is deferred until a network connection is established. Thus Gears enabled web applications to work even though access to the network service is not present. Google announced the end of Gears development on March 11, 2011, citing a shift of focus from Gears to HTML5.

Google Developer Groups

Google Developer Groups (GDGs) are communities of developers who are interested in Google's developer technology products and platforms. A GDG can take many forms—from just a few people getting together, to large gatherings with demos and tech talks, to events like code sprints and hackathons. As of June 2020, there are currently 1000+ GDGs worldwide. DevFest is one of these events.
