cros-anywhere is a free Chrome add-on developed by yaozeyuan93. It falls under the category of Browsers and is specifically categorized as an Add-ons & Tools subcategory.

The main purpose of cros-anywhere is to allow explicit requests from the origin domain and modify the Cross-Origin Resource Sharing (CORS) option response. It enables the modification of the `Access-Control-Allow-Origin` header to specify the origin host instead of the previous wildcard `*`. This is particularly useful when `Access-Control-Allow-Credentials` is set to true, allowing the transfer of cookies across domains.

With cros-anywhere, users can easily manage and customize the CORS settings for their Chrome browser. It provides a simple and accessible solution for dealing with cross-origin resource sharing, ensuring secure and efficient communication between different domains.

Please note that cros-anywhere does not provide any additional features or functionalities beyond the modification of the CORS options. It focuses solely on enhancing the CORS capabilities of the Chrome browser.
