Five domains watched daily, no card, no clock. Pro adds the deeper SSL and security watching for $15 a month.
forever, no credit card
Everything, on every plan:
monthly — no annual plan, no lock-in
Pro attaches to an account, so you'll sign in first — email, one-time link, no password. Starting an account is free either way.
Everything in Free, plus:
CT issuance monitoring
The moment any new certificate is issued for your domain, I'll write — including the ones you didn't request.
Nobody touches your domain's certificates without you knowing.
The free plan stays free. Pro is an addition, never a paywall around what you have today.
Calm questions get calm answers.
Yes. The free plan is the baseline, not a trial — no clock, no card, and no day where it quietly turns into something you pay for. Five domains, watched daily, for as long as you keep the account.
One domain is one site we watch — say apple.com. Each gets the full daily routine: certificate, reachability, and the complete snapshot. A subdomain you want watched separately counts as its own domain.
Not for the free plan. No card field, nothing to cancel later. Pro is the only thing that asks for one.
$15 a month, monthly only. It adds CT issuance monitoring, cert change-detection, hourly checks, and a ceiling of 25 domains. Stripe handles the payment; you can stop any month.
No. Nothing moved from free to paid. Five domains, daily checks, the full snapshot, and email alerts are all still free, exactly as before.
