Non-standard: This feature is non-standard and is not on a standards track. Do not use it on production sites facing the Web: it will not work for every user. There may also be large incompatibilities between implementations and the behavior may change in the future.

Whether the app or extension is expected to work offline. When Chrome detects that it is offline, apps with this field set to true will be highlighted on the New Tab page.

As of Chrome 35, apps (ChromeOS only from 2018) are assumed to be offline enabled and the default value of "offline_enabled" is true unless "webview" permission is requested. In this case, network connectivity is assumed to be required and "offline_enabled" defaults to false.

The "offline_enabled" value is also used to determine whether a network connectivity check will be performed when launching an app in ChromeOS kiosk mode. A network connectivity check will be performed when apps are not offline enabled, and app launching put on hold until the device obtains connectivity to the Internet.
