Run Chrome browser without CORS

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.

Windows

Just do follow steps:

• Right click on desktop, add new shortcut
• Add the target as "[PATH_TO_CHROME]\chrome.exe" --disable-web-security --disable-gpu --user-data-dir=%LOCALAPPDATA%\Google\chromeTemp
• Click OK.

NOTE: On Windows command will be: "C:\Program Files\Google\Chrome\Application\chrome.exe" --disable-web-security --disable-gpu --user-data-dir=%LOCALAPPDATA%\Google\chromeTemp

OSX

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

Linux

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.

Remark

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.
