Domains everywhere, no single place to see them.
Dozens of domains across different registrars and hosts. Certificates and registrations expire on their own schedules, and the reminders are scattered across inboxes and dashboards. One missed renewal can take a site down or hand a domain to someone else. SSLCanary puts them all in one list and warns you ahead.
What it watches
SSL and domain expiry are both first-class. We track each, and tell you plainly whether a site is fine.
SSL certificate expiry
We check the certificate on each site and warn you well before it expires, at the lead times you choose (30, 14, 7, and 1 day by default).
Domain-name expiry
We track each domain's registration and warn you before it lapses, so a renewal never slips through.
Is it OK right now
Plain-language status for every site: secure, expiring, expired, or not secure. No broken-chain jargon, just what to do.
The whole chain, not just the leaf
We check the full certificate chain, so an expiring intermediate is caught too, not only the site's own certificate.
How it works
- 1
Add your domains
Paste a list, or import a CSV, Excel, or OpenDocument file, or paste a public Google Sheet link. Never one at a time.
- 2
We watch them
We check SSL and registration on a schedule, from our own infrastructure. Nothing to install, no software on your servers. You can even check from the region you choose, for sites that behave differently by location.

We warn you ahead
Email by default, plus Slack, Teams, Discord, Telegram, or a webhook. You set the lead times, and every alert is logged.

A calm weekly digest
Once a week, a short summary of what needs attention, what is coming up, and, most weeks, an all-clear.
Full delivery history
Every alert, on every channel, with its delivery status. Nothing sent into the dark.
We tell you when we can't check
If a site stops responding, you get a clearly separate notice that we can't check that one, never mistaken for a healthy result.

Registrars remind you about your own domains. SSLCanary is for when you manage many, across providers, and need one calm place that warns you before anything lapses. Certificate lifetimes keep getting shorter, so there are more renewals to miss, not fewer.
Questions
- What is SSL certificate monitoring?
- SSL certificate monitoring means tracking when each of your sites' SSL/TLS certificates expire and whether they're valid right now, so you can renew before visitors ever see a security warning. SSLCanary does this for every domain you add and warns you in plain language, well ahead of time.
- How does SSLCanary warn me before a certificate or domain expires?
- You choose the lead times — 30, 14, 7, and 1 day by default — and the channels: email, Slack, Microsoft Teams, Discord, Telegram, or a webhook. SSLCanary checks each certificate and domain registration on a schedule and sends a heads-up before either lapses.
- Can SSLCanary monitor domain-name (registration) expiry too?
- Yes. Alongside SSL certificate expiry, SSLCanary tracks each domain's registration date and warns you before it lapses, so a missed renewal never quietly takes a site offline.
- How many domains can I monitor for free?
- Up to 5 domains free, with no card to start. Paid plans scale to 25, 100, 500, or 1000 domains for freelancers, teams, and agencies watching many sites across different registrars.
- Do I need to install anything on my servers?
- No. SSLCanary checks your sites from the outside, over the public internet — there is nothing to install and no sysadmin knowledge required.
