Google Developers (previously Google Code) is Google's site for software development tools[update], application programming interfaces (APIs), and technical resources. The site contains documentation on using Google developer tools and APIs—including discussion groups and blogs for developers using Google's developer products.
The site also features a variety of developer products and tools built specifically for developers. Google App Engine is a hosting service for web apps. Project Hosting gives users version control for open source code. Google Web Toolkit (GWT) allows developers to create Ajax applications in the Java programming language.
Google offers a variety of APIs, mostly web APIs for web developers. The APIs are based on popular Google consumer products, including Google Maps, Google Earth, AdSense, Adwords, Google Apps and YouTube.
The Google Data APIs allow programmers to create applications that read and write data from Google services. Currently, these include APIs for Google Apps, Google Analytics, Blogger, Google Base, Google Book Search, Google Calendar, Google Code Search, Google Earth, Google Spreadsheets, Google Notebook, and Picasa Web Albums.
The AdSense and AdWords APIs, based on the SOAP data exchange standard, allow developers to integrate their own applications with these Google services. The AdSense API allows owners of websites and blogs to manage AdSense sign-up, content and reporting, while the AdWords API gives AdWords customers programmatic access to their AdWords accounts and campaigns.
Google Plugin for Eclipse (GPE) is a set of software development tools that enables Java developers to design, build, optimize, and deploy cloud computing applications. GPE assists developers in creating complex user interfaces, generating Ajax code using the Google Web Toolkit, optimizing performance with Speed Tracer, and deploying applications to Google App Engine. GPE installs into the Eclipse integrated development environment (IDE) using the extensible plugin system. GPE is available under the Google terms of service license.
Google OR Tools provides programming language wrappers for Operational Research tools such as optimisation and constraint solving.
Google previously ran a project hosting service called Google Code that provided revision control offering Subversion, Mercurial and Git (transparently implemented using BigTable as storage), an issue tracker, and a wiki for documentation. The service was available and free for all OSI-approved Open Source projects (as of 2010, it was strongly recommended but no longer required to use one of the nine well-known open source licenses: Apache, Artistic, BSD, GPLv2, GPLv3, LGPL, MIT, MPL and EPL). The site limited the number of projects one person could have to 25. Additionally, there was a limit on the number of projects that could be created in one day, a 200 MB default upload file size limit, which could be raised, and a 5 GB per-project total size limit. The service provided a file download feature, but on May 2013 the creation of new downloads was disabled, with plans to disable it altogether on January 14, 2014. In March 2015, Google announced that it would be closing down Google Code on January 15, 2016. Most projects on the site entered read-only mode on August 24, 2015.
Residents of countries on the United States Office of Foreign Assets Control sanction list, including Cuba, Iran, North Korea, Sudan and Syria, are prohibited from posting to or accessing Google Code.
Gears was beta software offered by Google to enable offline access to services that normally only work online. It installed a database engine, based on SQLite, 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 (GDGs) are for developers who are interested in Google's developer technology. 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 March 2015, there are currently 600+ GDGs worldwide.
