The free plan stays free. Pro is an addition, never a paywall around what you have today.

A few honest answers

Calm questions get calm answers.

Is free really forever?

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.

What counts as a domain or monitor?

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.

Do I need a credit card?

No. You sign in with your email, we mail you a one-time link, and you add a site. There's no card field anywhere on the free plan — there's nothing to cancel later.

When does Pro launch?

It's on the trail. We're building cert change-detection and CT issuance monitoring first. We don't have a date to promise yet — we'd rather ship it right than ship it Tuesday.

Will my free plan change when Pro ships?

No. Everything you have today stays exactly as it is. Pro adds deeper watching on top — it is never a paywall placed around what's already free.
