What is CORS?

For security, browsers stop scripts from accessing URLs on different domains. This is done via CORS or Cross-Origin Resource Sharing. It is implemented by looking at the HTTP headers returned by a URL. So if you are on google.com and try to access example.com/font.ttf, it will only be allowed if example.com returns a header allowing it. Learn more.

What does this site do?

This site will make a test request to the URL and check if it has valid CORS headers. If it does, you should be good to go when using it in a browser.
