Is there a service for automatically checking the cross-browser compatibility of a site?

Question

Browsers

The essence of the question is clear from the subject. More specifically, you want to enter the site's URL and get human-readable information about which browsers are supported and why others are not supported. For example, "your site uses {such-and-such a feature} so {such-and-such a browser is not supported}".
Please recommend a similar tool!
