I felt the same so I've built https://cert.chief.app.

Also had to find another source for revoked test certificates for the homepage examples and found them here: https://www.ssl.com/sample-valid-revoked-and-expired-ssl-tls.... The badssl ones are expired too which means they are no longer revoked since revocation only lasts the lifetime of the certificates, which makes sense of course.
