# The best cron job monitoring tools in 2026

A cron job that stops running produces no error, no alert and no log line — it produces silence, which looks exactly like success. Here are the tools that notice, what each one actually measures, and how to pick between a heartbeat and full job telemetry.

A web server that dies tells you. A cron job that stops running does not: it
produces no error, no log line and no alert, because nothing ran to produce
them. The failure looks identical to a quiet, successful night — right up
until somebody notices that the backups are three weeks old.

That is the whole category. Every tool here solves it the same way — the job
calls a URL when it runs, and the tool complains when that call does not
arrive — and they differ in what else they record.

Prices checked against each vendor's public pricing page on
11 September 2026 .

## The two shapes of the problem

Before the list, the choice that decides which tool fits.

A heartbeat answers one question: did it run, on time? The job pings a URL
on completion, you declare the expected schedule and a grace period, and
silence past that window becomes an alert. It is simple, it catches the
failure that matters most, and it is enough for the large majority of jobs.

Job telemetry answers more: how long it took, whether it exited non-zero,
how that compares with last week, what it printed. Useful when a job silently
takes four times longer than it used to, or fails in a way that still exits 0.

Most teams need the first. A few need the second, and for them the answer
below is clear.

## Cronitor

What it is: the most specialised product on this list — cron monitoring
first, with uptime checks and status pages alongside.

Pricing: five monitors free at five-minute intervals; then $2 per monitor
per month plus $5 per user per month, unlimited of both.

Does well: real job instrumentation rather than a bare ping — run
duration, exit status, history you can compare against — plus a metrics API
if you want the data in your own dashboards.

Falls short: the pricing model. At ten monitors it is excellent. At two
hundred monitors and five people, do the multiplication before you commit; a
flat plan usually wins well before that.

Pick it if: cron and background jobs are the bulk of what you monitor, and
you want more than "it ran".

## Healthchecks.io

What it is: the open-source option, available hosted or self-hosted.

Does well: it does one thing and it is free to self-host. For a team that
already runs its own infrastructure and wants the simplest possible answer,
this is a reasonable place to stop.

Falls short: self-hosting a monitor has the same structural problem as
self-hosting anything that watches you — if it runs on the machine that
breaks, it breaks with it. And it is heartbeats only; there is no wider
monitoring around them.

Pick it if: you want heartbeats, nothing else, on your own hardware.

## Better Stack

What it is: heartbeats as part of a platform that also does monitoring,
logs, incident response and on-call.

Pricing: free tier 10 monitors and heartbeats; $29/month billed yearly for
a responder licence including 10 monitors.

Does well: cron alerts land in the same incident workflow as everything
else, with the rota attached.

Falls short: you are buying a platform. If cron monitoring is the only
thing you need, the responder-licence model is a lot of product to carry.

Pick it if: your alerts and your rota already live there.

## UptimeRobot

What it is: cron monitoring added to the best-known free uptime tier.

Pricing: 50 monitors free at five-minute intervals, any use including
commercial; €9/month for Solo.

Does well: the free allowance. Fifty heartbeats for nothing is hard to
argue with on a personal project.

Falls short: no login seats on the free plan, so the colleague who owns
the backups cannot see them. Heartbeats only, without job-level detail.

Pick it if: one person watches the jobs, and free matters more than
anything else.

## WatchFor

What it is: heartbeat monitoring as one of 25 monitor types, in a product
built around external checks.

Pricing: free plan 15 monitors at three-minute intervals with commercial
use allowed ; €7/month for 50 monitors, teammates included on every plan with
no per-seat fee.

Does well: heartbeats are counted in the same monitor allowance as
everything else, so a cron job costs the same as an HTTP check and nothing is
billed per job. Expected schedule, grace period, and an alert when a job goes
quiet or reports a failure. If your jobs sit alongside APIs, certificates,
DNS and mail that also need watching, they are all in one place with one
on-call rota.

Falls short: less job telemetry than Cronitor — we tell you it ran, when,
and whether it reported failure, not how its runtime is trending. If that
detail is what you are shopping for, Cronitor is the better tool and we would
rather say so.

Pick it if: cron is one of several things you watch, and you would rather
not run a second product for it.

## Side by side

Tool Free Entry paid Job telemetry Wider monitoring

Cronitor 5 monitors $2/monitor + $5/user Yes, deepest here Uptime, status pages

Healthchecks.io Self-hosted — Basic No

Better Stack 10 monitors $29/mo yearly Basic Logs, on-call, uptime

UptimeRobot 50, no team seats €9/mo Basic 10 check types

WatchFor 15 monitors €7/mo Basic 25 check types

Checked 11 September 2026 against published pricing.

## Three things to get right whichever you pick

Set the grace period from the job's real worst case, not its average. A
nightly backup that usually takes 20 minutes and occasionally takes 90 will
page you at 3am every month if the grace period is an hour.

Ping on success, not at the start. A job that pings when it begins and
then crashes has told you it ran. It has not told you it worked.

Alert on the job that stopped, not on the one that is late. A five-minute
job that is two minutes late is noise. A daily job that is six hours late is
an incident. If the tool makes you use one threshold for both, it will train
you to ignore it.

We make one of the tools here. Cronitor is better than us at the specific
thing this article is about, and that is written above rather than buried. If
any figure is out of date, tell us at [hello@watchfor.io](mailto:hello@watchfor.io) and we will correct
it.
