This is a comparison between two different jobs. Cert Spotter monitors certificate transparency logs to tell you when a certificate is issued for your domain — including ones you did not authorise. We warn you before your own certificate expires. Both matter; they are not substitutes.

Is MonitoringDaddy a real Cert Spotter alternative?
Honestly, no — not for what Cert Spotter is for. It watches certificate transparency logs for unauthorised issuance, which is a security control we do not offer in any form. If that is your requirement, buy Cert Spotter. We are an alternative only if what you actually wanted was an expiry warning.
Certificate transparency monitoring and certificate expiry monitoring are both "SSL monitoring" and are completely different. People often arrive looking for one and find the other.
For most small teams the realistic risk is their own certificate lapsing, not an attacker obtaining one for their domain.
Which is not something we solve — see the verdict above.
Green marks the stronger option on that row. Third-party pricing and limits change without notice — treat the SSLMate Cert Spotter column as a starting point and confirm current figures on their site before you decide.

Every comparison page on the internet claims the author's product wins on everything. Here is where it does not.
If any of those are load-bearing for your team, staying put is the correct decision and this page has done its job. Monitoring you actually trust beats monitoring that is marginally cheaper.
Six monitor types and one dashboard. No add-on products, no separate SKUs for the features you assumed were included.
HTTP checks from external infrastructure, as often as every 60 seconds, with downtime and recovery alerts. See the uptime setup guide.
A dedicated monitor type with configurable advance warnings, so a certificate never lapses because nobody owned the renewal. See SSL expiry monitoring.
Registration expiry tracked as its own monitor, warning you months ahead. The outage nobody has a runbook for. See domain expiration monitoring.
Alert when a phrase appears or disappears on a page — defacement, stock changes, silent policy edits. See website change detection.
Watch a competitor or supplier price string and get told the moment it moves. See the price monitoring guide.
Public status pages included on every plan, hosted independently of your infrastructure so they stay up when you do not. See hosted status pages.
Alerts from any of these can be routed to email, Slack, Microsoft Teams, Discord, Telegram, Flock or a generic webhook, and a single monitor can carry several channels at once. Everything is available through the REST API on paid plans, so monitors can be created and torn down programmatically rather than clicked through a form.
Flat monthly tiers. No per-seat charges, no credit top-ups, no usage meters — the number below is the whole bill.
| Plan | Monitors | Fastest interval | Alert channels | API | Price |
|---|---|---|---|---|---|
| Free | 1 | Every 30 minutes | — | $0 | |
| Founding Member first 20 only | 25 | Every 5 minutes | Email + webhook & chat | Yes | $5/mo |
| Basic | 10 | Every 10 minutes | Email + webhook & chat | Yes | $8/mo |
| Growth | 50 | Every 5 minutes | Email + webhook & chat | Yes | $19/mo |
| Pro | 100 | Every 60 seconds | Email + webhook & chat | Yes | $34/mo |
Annual billing is cheaper on every paid tier. The pricing page is the authoritative list.
There is no automated importer — monitors are re-created by hand, or scripted through the API on paid plans. Budget about a minute per monitor.
List every active check: URL, interval, condition and alert recipients. Most teams find monitors nobody needs any more.
Start with revenue-critical URLs. Set the interval, add the condition, attach the channels your team already watches.
Keep SSLMate Cert Spotter live while the new monitors settle. Compare alerts and confirm nothing is missing.
Move any public status page across, confirm a clean week of overlap, then cancel the old subscription.
This page is written by the team that builds MonitoringDaddy, so treat it as an informed argument rather than a neutral audit. What we can promise is that the claims about our own product are checked against what the software actually does, and the rows where SSLMate Cert Spotter is stronger are marked as such rather than quietly omitted.
Details about SSLMate Cert Spotter come from their public pricing and documentation at the time of writing. Monitoring vendors change plan limits and prices frequently and without announcement, so every third-party figure here carries a "verify on their site" caveat and you should take it seriously before making a decision on cost.
One thing worth stating plainly, because most comparison pages fudge it: MonitoringDaddy checks run from our own infrastructure, which is external to yours, but from a single origin rather than a global probe network. That is enough to catch outages and content changes independently of your stack. It is not enough to tell you a site is down in Frankfurt but up in Ohio. If regional verification is a hard requirement, a larger platform will serve you better and we would rather you knew that now.

Every recorded change is compared word by word and kept with a before-and-after image. This is the real output, shown with worked example data.
Price fell from $49 to $39, and an annual discount was added.
The item is available again and the basket button returned.
A new subprocessor was added in another jurisdiction.
The free plan sends to one email address. Every paid plan adds the chat and webhook channels below, with 2 to 10 destinations depending on the plan. However many alerts you receive, the price does not change — nothing here is metered or charged per alert.
There are no voice calls and no SMS. If a phone call at 3am is a hard requirement, say so before you subscribe — we would rather tell you now than refund you later.
Public logs record every certificate issued by participating authorities. Monitoring them tells you when a certificate is issued for your domain — including one obtained by someone else. Cert Spotter does this; we do not.
If unauthorised issuance is your concern, Cert Spotter, without hesitation. If your concern is your own certificate quietly expiring, that warning is included with every monitor here.
No. It is a genuinely different capability and we would rather say so than imply partial coverage.
Expiry warnings. We check the certificate on a monitored site and warn you as expiry approaches, well before renewal becomes urgent.
For most small sites, yes — the realistic failure is a renewal that did not happen. For anyone whose domain is a target for impersonation, CT monitoring is a separate and worthwhile control.
Yes, and for a security-conscious team that is the correct answer rather than a compromise.
Yes — one monitor with SSL and domain expiry warnings attached, at no cost and with no card.
No. We warn on approaching expiry only.
