Run Chrome browser without CORS

chrome browser cors debug development english

I use this sometimes, for posting a localhost frontend app to a localhost backend API. I created a separate shortcut on my Windows 10 laptop, so that it never is used for normal browsing, only for debugging locally.


Just do follow steps:

NOTE: On Windows 10 command will be: "C:\Program Files (x86)\Google\Chrome\Application\chrome.exe" --disable-web-security --disable-gpu --user-data-dir=~/chromeTemp


open -n -a /Applications/Google\\ Chrome --args --user-data-dir="/tmp/chrome_dev_test" --disable-web-security


google-chrome --disable-web-security

If you need access to local files for dev purposes like AJAX or JSON, you can use -–allow-file-access-from-files flag.


Since Chrome 22+ you will get 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.
