What is Google Gears?

Google Gears is an open source browser extension that lets developers create web applications that can run offline. Gears provides three key features:

  • A local server, to cache and serve application resources (HTML, JavaScript, images, etc.) without needing to contact a server
  • A database, to store and access data from within the browser
  • A worker thread pool, to make web applications more responsive by performing expensive operations in the background

Google Gears is currently an early-access developers' release. It is not yet intended for use by real users in production applications at this time.


If you're a developer interested in using Google Gears with your application, visit the Google Gears Developer Page.

If you wish to install Google Gears on your computer, visit the Google Gears Home Page. Please note, however, that Google Gears is not yet intended for general use.
