Cronjob.de features

Cronjob.de calls your URLs on schedule, logs your server's response and tells you when something breaks. No cron daemon of your own, no server access needed, in operation since 2003.

NEW: SET UP WITH AI

Paste the instructions, we build the cronjob

Almost every set of instructions from a host, a shop or a CMS ends in a text that beginners cannot use. Just paste it here. We read out the address, the method and the schedule, ask if something is missing, and fill in the form with it. Nothing is saved until you submit it yourself.

Hoster instructions or crontab line – a curl or wget command works too
Asks instead of guessing – for the domain, say, when only a path is given
Says so when it will not work – for a command that only runs on your own server
Or just the schedule – „every second Tuesday of the month at 6:45" becomes 45 6 8-14 * 2
A suggestion, not a decision – nothing is applied without your check
You see when it runs – the next execution times are shown in plain text on the cronjob before you save

Try it now in the crontab generator

Schedule builder at Cronjob.de: minutes 15, 30 and 45 selected, all hours and weekdays, resulting in the cron expression 15,30,45 * * * * and the next executions

Scheduling

Minute-precise, by click or cron expression

Pick minutes, hours, days, months and weekdays. If you know crontab syntax, just type it in. Both ways lead to the same result, and you immediately see when the job runs next.

Every minute down to once a year – any combination, including several times per hour
Folders – group cronjobs by project or customer
Test right away – start a job manually and see the response immediately
Password protected targets – credentials in the URL, also for .htaccess protection

Look up crontab syntax

A form with request method POST, the custom header X-Api-Key and a JSON body, next to it the server response with 200 OK after 0.31 seconds

APIS

Not just call it, hand something over

You choose the method, send data along and set your own headers. That lets you drive someone else's API just as well as your own scripts – from handing an order to an ERP system to calling a service's webhook.

POST, PUT, PATCH, DELETE, HEAD – alongside GET, in every plan
Request body – JSON, form data or text, with the matching content type
Custom headers – an API key or a token, for example
Credentials in separate fields – any special characters in the password, and it never appears in the call log

Looking for an API to Cronjob.de itself? That exists as an MCP connection: manage cronjobs with Claude, ChatGPT or your own scripts.
You will find this in the Advanced tab when creating a cronjob.

Call log

You see what your server answered

A cronjob that seems to run but does nothing is the most expensive kind of failure. That is why Cronjob.de stores your script's response for every call, not just a checkmark. This cronjob log is available in your account at any time.

The last 20 runs – with date, time and the HTTP error in plain text
Up to 5,000 characters of output – from the latest run, older ones trimmed to 500
Duration and size – how long your script took and how much it returned

Statistics

When a script slowly gets slower

The last 200 runs form a curve for duration and output size. That is how you spot an import that grew from 2 to 20 seconds, or an interface that has been returning empty responses since yesterday.

Failed runs as red dots
Time limit shown as a line in the chart

Included in the Unlimited plan.

How error detection works at Cronjob.de: the server answers with an error, Cronjob.de records it, the team receives an email

Notification

You find out before your customer calls

If your server answers with an error or not at all, you get an email. We report the change, not the ongoing state: a cronjob that runs every minute and fails produces exactly one message – and a second one when it works again.

An all-clear as soon as it works again
A second server verifies before we wake you
For all cronjobs or only for selected folders
Recipients of your choice, several possible
Optionally also as a webhook to your own system

SSL MONITORING New

We see when your SSL certificate expires

Every time we call your cronjob we also see how long the certificate of that address is still valid. On request we let you know in good time – by email, to a different address than the cronjob alerts if you like.

Sounds like yesterday's problem now that Let's Encrypt renews itself? In practice things still expire: a certificate somebody bought by hand, a renewal that quietly fails, a subdomain nobody thinks about any more. An expired certificate stops payments and interfaces, and nobody tells you – until a customer calls.

Nothing to set up – we already know your addresses, a switch is enough
Twice, not once – once early enough to plan, and again shortly before it expires
Its own address – your tech people need to know, not necessarily accounting
Visible in your account – remaining validity and issuer of all your addresses on one page

Included in the Unlimited plan. Off by default – you decide whether you want to hear about it.

MAINTENANCE MODE New

One switch while you work on your server

Installing an update, migrating, backing up the database – and your cronjobs keep running and keep failing. That costs error notifications, needless load and, in the worst case, half-finished imports. One click pauses everything, a second one starts it again.

The difference to switching things off by hand: we remember what was running. When you end it, exactly that state comes back – cronjobs you had deliberately switched off stay off. With 200 cronjobs you would otherwise have to tick them one by one and remember which ones they were.

All or part of it – the whole account, or just the folders whose system you are touching
Automatic end – 1 to 24 hours, so nobody forgets – paused cronjobs do not report anything
No error emails – while it is on, everything stays quiet
Schedules stay – nothing is rewritten, nothing is lost

Included in the Plus and Unlimited plans. You can end it by hand at any time.

Team logins New

Several people, one account

Colleagues get their own login with their own email address and password. Everyone works under their own name, and when someone leaves, exactly their access goes – everyone else keeps theirs.

Two roles – members work with the cronjobs, admins also with invoices, plan and team
Invitation by email – a link valid once, revocable at any time
Activity log – who created, changed or deleted which cronjob, and when
One person, several accounts – agencies switch between their clients' accounts from the menu
No limit – included in the Unlimited plan

Which of my cronjobs failed last week?

Two: „Database backup" (404) and „Newsletter" (timeout). Shall I look at the log?

Create a job that syncs the inventory on Sundays at 4 a.m.

Created: „Sync inventory", 0 4 * * 0. Next run on Sunday at 4:00.

AI access (MCP) New

Manage your cronjobs in conversation

Cronjob.de speaks the Model Context Protocol, MCP for short. Connect Claude, ChatGPT, Cursor or another assistant to your account and just ask – instead of clicking through lists.

Enter the address, confirm in the browser – no token to copy
You decide whether the assistant may only read or also make changes
Every connection can be removed in your account at any time
Included in the Unlimited plan

How to connect your assistant – step by step

Cronjob.de infrastructure: six scheduler servers in Helsinki, Nuremberg and Falkenstein working from the same job list

Operations

Several data centres, so your job actually runs

Calls are spread across independent machines in Helsinki, Nuremberg and Falkenstein. Each takes its share of the jobs from the same list. If one fails, the others keep going.

Operated from Germany – German company, German support, invoice with VAT shown
GDPR compliant – servers in the EU, your data is not passed on
Two-factor login – optional, by email code
Running since 2003 – one of the first web cron services there was
Renewable electricity – according to their operator the data centres run entirely on hydropower, in Finland also on wind
