Disable same origin policy in Chrome


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


Solution

  • 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).

    Note: Kill all Chrome instances before running this command.


    For me the exact command was:

    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
