Simple REST API

Wrap any job with a single curl. No SDKs, no agents - just standard HTTP.

# mark job complete
curl -X POST https://api.cronitorex.com/ping/backup \
  -d 'status=complete'

How it works

Three pings. Complete visibility.

Three step ping flow: run, execute, complete

One HTTP request per ping. Cronitorex correlates them into a timeline, detects missed runs, and pushes alerts within seconds. No agents. No daemons. Just three pings.

1

Job starts

Send a run ping at the beginning of your job.

{"status": "run"}
→
2

Job runs

Your actual task executes. Cronitorex waits.

/usr/bin/backup.sh
→
3

Result recorded

Send complete or fail. Dashboard updates instantly.

{"status": "complete"}

Who it's for

Six typical scenarios where Cronitorex earns its keep.

1

Solo founder

Your production cron crashed Saturday. Find out Sunday morning when customers wake up and complain? Cronitorex pings you in 60 seconds - email, Slack, webhook to any endpoint.

Sleep through the night.

DevOps lead

Hundreds of crons spread across 12 servers. Cronitorex shows them all in one view, alerts on missed runs, captures stderr on fail, dashboard tells you what crashed today without ssh-ing into 6 machines.

12 servers · 1 dashboard.
client-acme client-globex client-initech client-umbrella

Agency / SaaS

Each client = separate tag, own notifications, own dashboard. Onboard a new client in 5 minutes - monitoring their crons comes free. No logging into 30 different panels.

One panel per client.

Data engineer

Hundreds of batch jobs, nightly ETL processes, data pipelines. Cronitorex hooks into any task - ping run at the start, complete on success, fail on any exception. Spot a broken pipeline before downstream tables go stale.

Catch broken pipelines before reports do.

E-commerce / Ops

Hourly catalog imports, payment webhooks, stock sync to 3 warehouses, EOD reconciliation. When any of them silently stops, you lose orders. Cronitorex pages you the moment one misses its window.

No silent revenue leaks.

Compliance / SRE

90-day event history, audit trail, SSL expiry, SLA reporting. CSV export, archives, no log stack to maintain. Show auditors your backup ran every day for the past year.

90-day audit trail, on demand.

Questions that keep coming up

Can I use it in production during beta?

Yes. Beta doesn't mean "unfinished and unstable" - it means "limits are looser and we're gathering real usage data to calibrate paid plans". Production traffic welcome.

What happens to my account when paid plans launch?

Accounts created during beta get a founding user flag. After launch: stay on Free with relaxed beta limits (current), or take Pro at 50% off forever. Your call.

Can I migrate from another monitoring tool?

Cronitorex exposes a standard HTTP API with run/complete/fail pattern. If your current tool uses a similar ping model, migration is just changing URL and API key in existing scripts. Full API reference at docs.cronitorex.com.

Do you have Slack and webhook integrations?

Email and webhook notifications are available in all plans. Slack integration is planned for the Pro plan. Webhooks let you connect any HTTP endpoint, enabling integration with any external service yourself.

Is my data safe?

Hosted on our own infrastructure in the EU, GDPR-compliant. All traffic over HTTPS (TLS 1.3) - no ping ever travels in plaintext. The database sits on a private network, accessible only from our application services. User passwords stored as cryptographic hashes. You can rotate your API key at any time from the profile page - the old one stops working immediately. Daily database backups, encrypted, 30-day retention. Full data export and account deletion from the dashboard. We do not sell or share data with third parties. Need an audit report or on-prem deployment? Email hello@cronitorex.com.
