CORS Header Checker

Sends a real request to any URL you provide, attaches an Origin header, and reads back all six standard cross-origin permission headers the server returns. Tells you whether cross-origin requests are enabled at all, whether your specific origin is permitted, and shows you every permission value exactly as the server sent it. Perfect for figuring out why a browser is blocking a request, confirming a freshly deployed service is configured correctly, or auditing whether a public API allows credentialed cross-origin calls.
