I made https://monitorcertificates.com from this simple script - https://hackernoon.com/monitor-your-https-certificate-expiry...

It reminds you when your certificates are due for renewal, or if they have been configured incorrectly.

The way you sell it seems pretty effective. Do you have any "big boy" clients yet?

No, mostly devs who have been burned by bad certs, and devs who's boss bought a certificate and now doesn't remind devs when they get a "reminder" to renew.
