Gears, formerly Google Gears, is discontinued utility software offered by Google that aimed to facilitate creating more powerful web apps by adding offline storage and other additional features to web browsers. Released under the BSD license, Gears is free and open-source. Gears was conceived at a time when a comparable alternative was not available. However, Gears was discontinued in favor of the standardized HTML5 meaning that eventually became prevalent.
Gears did not support attachment files with sizes greater than 2 GB under Mac OS X Leopard or Snow Leopard due to a bug in the Blob handling code.
On May 29, 2008, Opera Software ASA announced that Opera Mobile 9.5 would support Gears.
The technology preview release of the browser was published on February 20, 2009.
It was available for touch-screen devices on Windows Mobile 5 & 6 only. Gears was not built into browsers other than Google Chrome and had to be downloaded separately.
The Ruby on Rails framework supported interfaces to Gears without needing to understand the Google Gears API.
End of life
In late November 2009, numerous online news sources reported that Google was going to migrate to Web Storage rather than use Gears in the future. A Google spokesman later clarified that Google would, however, continue to support Gears so as not to break sites using it. On February 19, 2010, the Gears team at Google announced that the development of Google Gears had stopped, as they are working on bringing all of the Gears capabilities into web standards like HTML5. Although development of new features had ceased, Google was planning to continue supporting Gears until they have developed a "simple, comprehensive" method for users' data to be migrated to HTML5 features. On 22 November 2011, Google announced that on 1 December 2011, Gears support would be removed from Gmail and Google Calendar. Gears was removed from Google Chrome on June 7, 2011.
