Who CORS? is a free Chrome add-on developed by whocors. It falls under the category of Browsers and is classified as an Add-ons & Tools subcategory. This plugin aims to ease Cross-Origin Resource Sharing (CORS) related issues for developers.

With Who CORS? enabled, developers can make requests to domains without worrying about CORS. The add-on allows users to whitelist specific domains, ensuring that requests and responses won't fail if the appropriate CORS headers are not set.

Who CORS? is a fork of the popular "Allow-Control-Allow-Origin: *" extension available on the Chrome Web Store. It offers the same functionality but with the added benefit of being able to configure the origin.

For developers looking to handle CORS-related problems more efficiently, Who CORS? is a valuable tool that simplifies the process of making requests to domains without CORS restrictions.
