SSLMate-style SSL monitors costs $10–20/mo — and unlike a tool you buy once, that bill never stops. Over three years that's roughly $540 for software doing a job your own hardware could just as easily do.
Where the subscription actually goes
$10–20/mo is the sticker price. It compounds: cancel and you typically lose access to your own history, and most plans ratchet the price up as you add usage, seats or storage — the bill rarely stays flat for long.
Certwatch: the pay-once alternative
Certwatch does the same core job for $24, once. Real TLS handshake checks on a schedule with 30/14/7/1-day email and webhook alerts.
| Certwatch | SSLMate-style SSL monitors | |
|---|---|---|
| Price | $24 once | $10–20/mo |
| 3 years, 50 domains | $24 | $360–720 |
| Handshake checks (expiry, chain, keys) | Yes | Yes |
| Domain (WHOIS) expiry | Yes, best-effort | Sometimes |
| Email + webhook alerts | Yes | Yes |
| Data on your server | Yes | No |
| Domain limits | None | Usually tiered |
| Source you can read | Yes, MIT | No |
Two months of a paid SSL monitor covers Certwatch, and one cert it saves from expiring covers the 2am page it would have cost you.
Is the subscription ever still worth it?
If you need SSLMate-style SSL monitors's specific ecosystem, integrations or managed infrastructure and that's genuinely load-bearing for you, the subscription earns its keep — that's a real trade-off, not a trick. Certwatch is for everyone else: people paying every month for a job that runs fine on hardware they already own.
