Every account now gets one HTTPS certificate monitor free, forever. It runs the same checks as a paid monitor: expiration, chain and trust, hostname coverage, revocation, CAA, and fingerprint changes, with alerts on every channel your account uses. There is no trial period and no credit card required.
HTTPS Only
The free monitor covers HTTPS. Monitors on other protocols, including STARTTLS for SMTP, IMAP, and LDAP, are billed at the standard $0.01 per host per day.
The free monitor keeps being checked when your balance runs out. Only paid monitors stop until you add funds.
On Your Bill
The free monitor shows up in your charges and monthly history as its own $0 line, next to your paid monitors.
