No event quota, no platform to adopt

The Sentry Crons alternative without the platform around it

Sentry Crons is cron monitoring added to an error-tracking platform. If you already run Sentry, having jobs and exceptions in one place is a real advantage. If you do not, you would be adopting a whole platform to watch a backup script.

Is MonitoringDaddy a real Sentry Crons alternative?

For teams who want cron monitoring without adopting an error-tracking platform, yes, and with uptime and page monitoring alongside. Sentry remains the right answer if you already use it — jobs sitting next to the exceptions they throw is genuinely valuable and we cannot offer that.

The trigger

Why people look for a Sentry Crons alternative

You do not use Sentry

Adopting an APM and error-tracking platform to monitor a nightly job is a lot of tool for the problem.

Quota-based pricing is hard to predict

Sentry bills on events and volume. That is reasonable for error tracking and awkward when all you wanted was a heartbeat.

It does not watch your website

Sentry sees errors your code reports. It does not tell you the site is unreachable, the certificate expired or a page changed.

Side by side

Sentry Crons vs MonitoringDaddy

Green marks the stronger option on that row. Third-party pricing and limits change without notice — treat the Sentry Crons column as a starting point and confirm current figures on their site before you decide.

Feature Sentry Crons MonitoringDaddy
Cron / heartbeat monitoring Yes — check-ins, with duration and status Yes — 1 on free, 25 on the $5 plan, 100 on Pro
Errors linked to the failing job Yes — the whole point, if you use Sentry No — we have no error tracking
Error tracking and performance monitoring Yes, extensively No
Uptime monitoring from outside Limited — Sentry has added uptime checks; verify scope Yes, on every plan, with incidents
SSL and domain expiry No Yes, at no extra allowance
Website change detection No Yes, with before/after images
Hosted status page No Yes, included on every plan
Pricing model Event and volume quotas Fixed slots — nothing metered
Entry paid price From ~$26/mo — verify on their site $5/mo for 25 of each monitor type
Complexity for cron alone High — a full platform Low — name a job, set a period, paste a URL
Fair comparison

What Sentry Crons does better

Every comparison page on the internet claims the author's product wins on everything. Here is where it does not.

  • If you already run Sentry, a failed job and the exception that caused it appear together. Nothing here matches that.
  • Captures check-in duration and status, not just arrival.
  • Mature SDKs in every major language, so instrumenting a job is often a decorator rather than a curl line.
  • Error tracking and performance monitoring that we do not attempt at all.

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.

The product

What you actually get with MonitoringDaddy

Six monitor types and one dashboard. No add-on products, no separate SKUs for the features you assumed were included.

Uptime monitoring

HTTP checks from external infrastructure, as often as every 60 seconds, with downtime and recovery alerts. See the uptime setup guide.

SSL certificate expiry

A dedicated monitor type with configurable advance warnings, so a certificate never lapses because nobody owned the renewal. See SSL expiry monitoring.

Domain expiry

Registration expiry tracked as its own monitor, warning you months ahead. The outage nobody has a runbook for. See domain expiration monitoring.

Content change detection

Alert when a phrase appears or disappears on a page — defacement, stock changes, silent policy edits. See website change detection.

Price monitoring

Watch a competitor or supplier price string and get told the moment it moves. See the price monitoring guide.

Hosted status pages

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.

The decision

Who should switch — and who should stay

Switch if…

  • You do not otherwise use Sentry and only need job monitoring.
  • Event-quota billing is unpredictable for what you actually use.
  • You also need uptime, certificate, domain or page-change monitoring.
  • You want a status page in the same account.

Stay on Sentry Crons if…

  • You already use Sentry — jobs beside exceptions is a real advantage.
  • You need error tracking or performance monitoring, which we do not do.
  • Your jobs are instrumented through Sentry SDKs already.
Pricing

What MonitoringDaddy costs

Flat monthly tiers. No per-seat charges, no credit top-ups, no usage meters — the number below is the whole bill.

Annual billing is cheaper on every paid tier. The pricing page is the authoritative list.

Migration

Moving from Sentry Crons without a gap in coverage

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.

1

Audit what you monitor

List every active check: URL, interval, condition and alert recipients. Most teams find monitors nobody needs any more.

2

Re-create the critical ones

Start with revenue-critical URLs. Set the interval, add the condition, attach the channels your team already watches.

3

Run both for a week

Keep Sentry Crons live while the new monitors settle. Compare alerts and confirm nothing is missing.

4

Switch over and cancel

Move any public status page across, confirm a clean week of overlap, then cancel the old subscription.

Methodology

How this comparison was put together

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 Sentry Crons is stronger are marked as such rather than quietly omitted.

Details about Sentry Crons 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.

FAQ

Sentry Crons alternative: your questions answered

What is Sentry Crons?

Cron monitoring built into Sentry's error-tracking platform. Jobs check in, and a missed check-in raises an issue alongside your application errors.

Should I use it if I already use Sentry?

Probably yes. Having a failed job appear next to the exception it threw is genuinely useful, and we cannot offer that because we have no error tracking.

And if I do not use Sentry?

Then you would be adopting a substantial platform to watch scheduled jobs. A standalone heartbeat — here or at Healthchecks.io or Cronitor — is a much smaller commitment.

Does MonitoringDaddy do error tracking?

No. We check from the outside: is the site responding, has the page changed, did the job check in. What your code threw internally is Sentry's domain, not ours.

How does pricing compare?

Sentry bills on events and volume, which is sensible for error tracking and hard to predict if you only wanted heartbeats. Our plans are fixed slots with nothing metered — $5/month for 25 heartbeats, 25 monitors and 25 watched pages.

Can Sentry monitor my website uptime?

Sentry has added uptime checking; verify its current scope against what you need. Incident handling, SSL and domain expiry, status pages and page-change monitoring are all included here.

How do I instrument a job here?

Call the heartbeat's ping URL at the end of the job, only on success. No SDK required, which also means no SDK available — Sentry's libraries are more convenient if you want duration captured automatically.

Can I run both?

Yes, and it is a sensible split: Sentry for what your code does, this for whether the site and its jobs are alive.
