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

Close chrome (or chromium) and restart with the --disable-web-security argument. I just tested this and verified that I can access the contents of an iframe with src="http://google.com" embedded in a page served from "localhost" (tested under chromium 5 / ubuntu). For me the exact command was:

Note : Kill all chrome instances before running command

chromium-browser --disable-web-security --user-data-dir="[some directory here]"

The browser will warn you that "you are using an unsupported command line" when it first opens, which you can ignore.

From the chromium source:

// Don't enforce the same-origin policy. (Used by people testing their sites.)
const wchar_t kDisableWebSecurity[] = L"disable-web-security";

Before Chrome 48, you could just use:

chromium-browser --disable-web-security

Answer 2

For Windows:

(using windows 8.1, chrome 44.0)

First, close google chrome.

Then, open command prompt and go to the folder where 'chrome.exe' is.

( for me: 'chrome.exe' is here "C:\Program Files (x86)\Google\Chrome\Application".

So I type: cd C:\Program Files (x86)\Google\Chrome\Application )

now type: chrome.exe --disable-web-security

a new window of chrome will open.
