Does Chrome have the "Work offline" option?

Question

I am trying to check my fallback page in html5 cache manifest. I would rather not actually disconnect from the Internet to do this. I heard that Chrome doesn’t work in Chrome, so I need to check it specifically. Does Chrome have the ability to work offline? I looked through the settings and available extensions, and I can not find anything.

Answer 1

It looks like Chrome now has this feature using the Chrome Developer Tools (Ctrl-Shift-I). Click on the "Device Mode" icon in the upper left corner. Now the device and network bandwidth and latency (or fully autonomous) can be modeled using the drop-down menus at the top of the screen:

The screenshot above is the version of Chrome version 42.0.2311.60 beta (64-bit) on Linux.

NOTE. By 2015, unfortunately, this does not affect Websocket connections, which continue to work regardless of network settings. See https://code.google.com/p/chromium/issues/detail?id=423246 .

Chrome has a flag called "Enable showing saved copy button."
Find the flag by visiting the chrome://flags/#show-saved-copy URL chrome://flags/#show-saved-copy

Enable showing saved copy button
When the page does not load, if an outdated copy of the page exists in the browser’s cache, a button will be presented allowing the user to download this outdated copy. The main allowing selection makes the button in the most noticeable position on the error page; secondary enable selection makes it secondary to the reset button.

Note that this flag was called "Enable offline download."

Gmail also has a standalone option. Gmail Offline is a Google Chrome app that lets you read and manage messages when you don’t have an internet connection. You can even create messages that will be sent when you are online again.

Google chrome itself does not have this feature, however, I found this page to do exactly what with the extension.

It works by routing chrome traffic to a proxy server, which you specify where there is no proxy server, and therefore will not receive any network traffic.

Answer 4

Offline Switch is Chrome’s new convenient extension for quickly completing this task. You can switch between offline and online on Google.

The add-on is simple, just to install a Chrome proxy on a non-existent point.

Answer 5

As far as I know, Google Chrome does not have offline mode, so disconnecting from the Internet is the only way I can imagine it.
