Disable same origin policy in Chrome

Question

Is there any way to disable the Same-origin policy on Google's Chrome browser?

This is strictly for development, not production use.

Answer 1

For Windows... create a Chrome shortcut on your desktop.
Right-click > properties > Shortcut
Edit "target" path :

"C:\Program Files\Google\Chrome\Application\chrome.exe" --args --disable-web-security

(Change the 'C:....\chrome.exe' to where ever your chrome is located).

et voilà :)

Answer 2

Don't do this! You're opening your accounts to attacks. Once you do this any 3rd party site can start issuing requests to other websites, sites that you are logged into.

Instead run a local server. It's as easy as opening a shell/terminal/commandline and typing

cd path/to/files
python -m SimpleHTTPServer

Then pointing your browser to

http://localhost:8000

If you find it's too slow consider this solution

Answer 3

Yep. For OSX, open Terminal and run:

$ open -a Google\ Chrome --args --disable-web-security --user-data-dir

--user-data-dir required on Chrome 49+ on OSX

For Linux run:

$ google-chrome --disable-web-security

Also if you're trying to access local files for dev purposes like AJAX or JSON, you can use this flag too.

-–allow-file-access-from-files

For Windows go into the command prompt and go into the folder where Chrome.exe is and type

chrome.exe --disable-web-security

That should disable the same origin policy and allow you to access local files.

Update: For Chrome 22+ you will be presented with an error message that says:

You are using an unsupported command-line flag: --disable-web-security. Stability and security will suffer.

However you can just ignore that message while developing.
