Features
Run it, watch it,
and show it.
CronEngine runs your scheduled work, watches the things you cannot see, and gives you a page to put in front of your customers when something goes wrong.
Run it
Cron jobs
We call your URL on a schedule.
- Visual schedule builder with next-run preview
- Every minute down to once a year, or just once
- Headers, body, variables and curl import
- Chained jobs and retries you opt into
- Full run history with charts

Heartbeats and uptime
We notice when something goes quiet.
- Heartbeats for scripts on your own servers
- Run time measured from start to finish
- Uptime checks as often as every minute
- Slow, down, and confirmed before it alarms
- Certificate expiry warnings
Show it
Status pages
Your customers check for themselves.
- Pick which monitors appear
- Post updates and planned maintenance
- Your logo, colours, light or dark
- Five languages, your timezone
- Your own address on Pro and up
Run it
Cron jobs that
tell you what happened.
We call your URL on a schedule, keep a record of every run, and warn you when one fails. No server crontab to babysit.
Scheduling
Build a schedule without guessing.
Set minute, hour, day, month, and weekday with visual controls, type raw cron directly, or use a shortcut such as @hourly or @daily. The schedule is checked as you type and the upcoming runs update with it.
- Visual dropdowns and raw input work together
- Preview the next runs in your own timezone before you save
- Weekday, monthly and last-day patterns, plus shortcuts
- Run once at a set moment instead of on repeat
- Overlapping runs are skipped, unless you turn that off

Requests
Send exactly the request your endpoint expects.
Pick the method, add headers and a body, and drop in variables such as the current time or the job’s name. Already have a working curl command? Paste it and the form fills itself in.
- GET, POST, PUT, PATCH, DELETE or HEAD, with headers and a body
- Variables filled in at the moment each run fires
- Decide what counts as success: status codes and words in the reply
- Retries for short hiccups, from the Starter plan up
- Chain jobs so one starts when another finishes, from Starter up
- Test the request before you save it
History
Debug failed runs in seconds.
Every run keeps its status code and how long it took. Turn on response storage and we also keep up to 10 KB of what your endpoint answered, clearly marked when it was longer.
- Status, duration, and up to 10 KB of the response
- A chart per job that shows failures and slowdowns at a glance
- From 5 stored runs per job on Free up to 50 on Enterprise
- Export the history as a CSV file

Watch it
Find out when something
quietly stopped.
A failed request is easy to spot. A backup that never started is not. Heartbeats and uptime monitors catch the silence.
Heartbeats
Your script checks in. We notice when it does not.
For work that runs on your own servers: backups, queue workers, imports. Add one line to the end of the script and it pings a private address when it finishes. If that ping is late, we alert you.
- Expect a ping every few minutes, hours or days, or on a cron schedule
- A grace period, so a slow night does not count as a failure
- Send a start ping too and we measure how long each run took
- Report a failure straight away with a fail ping
- Pings are free and never count against your scheduled runs
Uptime
Know your site is down before your customers do.
Give us an address and we check it from our side, judging every answer by the same rules a cron job uses. One bad second does not wake anybody, and every outage is recorded with its start, end and how long it lasted.
- Checks every 15 minutes on Free, down to every minute on Pro and up
- Success rules: status codes, plus words the page must contain
- Marked slow when it answers later than the limit you set
- Waits for several failed checks in a row before calling it down
- Certificate expiry warnings, from the Starter plan up
Show it
A status page that
looks like yours.
Hand out one link and stop answering “is it down for you too?”. You choose what appears, and the addresses you are watching are never shown.
Status pages
Tell everyone at once, instead of one by one.
Pick which heartbeats and uptime monitors appear, group them, and publish. When something breaks, post a short update and change it as things move on. Planned maintenance goes on the same page, ahead of time.
- Updates marked investigating, identified, monitoring or resolved
- Planned maintenance announced before it starts
- Daily bars and an uptime figure over 7, 30 or 90 days
- Past incidents folded away underneath
- From the Starter plan up, with more pages and monitors on higher plans
Make it yours
Your brand, not ours.
Change the look in the editor and see the page change next to it as you go. Every option below comes with every status page.
Light, dark or automatic
Pick a theme, or follow whatever your visitor’s device is set to.
Your colours
An accent colour for headings and buttons, a filled or plain header, a tinted or plain background.
Compact or roomy
A tighter layout for long lists, and the choice to hide the uptime figures, history or support link.
Your own address
Put the page on status.yourcompany.com. We handle the certificate. On Pro and up.
Language and timezone
English, Dutch, French, German or Spanish, with times shown in your timezone.
Link back to your site
A button to your website and a short line of your own in the footer.
Honest numbers
A monitor only counts the time it has been watching, so a new one never claims a record it has not earned.
For all three
The same tools, everywhere.
Cron jobs, heartbeats and uptime monitors share one way of working. Learn it once.
Organisation
Keep production, staging, and clients apart.
Maps group related items. Tags add labels for type, priority, or team. Together they keep a growing dashboard easy to scan.
- Maps and tags on jobs, heartbeats and uptime monitors
- Select several at once to pause, resume or delete them
- A test button on every job and monitor
- Copy a job or monitor instead of starting over

Notifications
Hear about it wherever your team works.
A heartbeat or uptime monitor tells you when it goes down and again when it comes back. For a cron job you choose: every failure, down and back, after a number of failures in a row, every run, or never. Alerts go to email, Slack, Discord, Telegram or your own webhook.
- Failure, recovery and threshold alerts for jobs on every plan
- Maintenance windows hold alerts back but still record the outage
- A weekly or monthly email digest with totals and failures
- Signed, versioned webhook events for your own systems
- More channels per job on higher plans

Everything else worth knowing
Flexible scheduling
Run from every 15 minutes on Free down to every minute on Business and Enterprise.
Timezone support
Each job runs in your account timezone and recalculates when it changes.
Pause and resume
Pause any job or monitor without losing its address, schedule, or settings.
One address to allow
Every request we make comes from the same place, so you only have to let us in once.
Generous request timeouts
Every job gets your plan's timeout automatically, from 20 seconds on Free up to 10 minutes on Enterprise.
Import and export
Paste a line from your crontab or a CronEngine export into the job form and it fills itself in.
Stops itself when stuck
On the Free plan, a job that fails 20 times in a row pauses itself and tells you, so a broken endpoint stops using up your runs.
Secure by default
Your account, your credentials and anything you store with us are protected as standard, on every plan.
Read about security ›History you can take with you
Download the history of any job or monitor as a CSV file.
