You're the one who gets blamed

When a client's site shows "not secure" or their domain lapses, they call you — even if it was their registrar's job. SSLCanary quietly watches every site you look after and warns you first, so you fix it before anyone notices.

How SSLCanary keeps you ahead

  1. 1

    Add your sites

    Paste your list or import a CSV, Excel file, or Google Sheet — we start checking right away.

  2. 2

    Set your lead times

    We warn you 30, 14, 7, and 1 days ahead by default. Change them, or add channels.

  3. 3

    Get warned in time

    A plain-English heads-up lands well before anything expires.

Everything in one place

Lead-time alerts

30 / 14 / 7 / 1 days before expiry, or whatever schedule suits you.

Is it OK right now?

Plain status: valid, expiring, expired, or not secure — no jargon.

SSL and domain, together

Certificate and registration expiry, watched side by side.

Common questions

Is it really free to start?
Yes — monitor up to 5 domains free, forever, with no card. Paid plans start small and grow only as you take on more sites.
Can I keep client sites organized?
Yes. Group and label sites by client so your list stays tidy as you add more work.
Does it cover domain renewals too?
Yes. It watches both the SSL certificate and the domain-name registration for every site, so nothing lapses on your watch.
Do I need to be technical?
No. Status is in plain English — "secure", "expiring in 9 days", "not secure" — with what to do, never certificate jargon.
Do I have to install anything?
No. SSLCanary checks each site from the outside — nothing to install on your or your clients' servers.
