DISCLAIMER: This tool circumvents CORS security rules baked into the browser and is intended for testing your own website during development. Some production websites like Google Docs or Facebook may not work if they detect something has been tampered with. You can use the whitelist feature to only turn on for some domains. To avoid security issues, it is recommend to turn off after debugging.
