Never Lose Revenue to Undetected Downtime Again
CronJobPro pings your website on a schedule you define and alerts your team the moment something goes wrong. With automatic retries and multi-channel notifications, you catch outages before they cost you customers.
Downtime Goes Unnoticed Until Customers Complain
Most teams discover their website is down when angry customers flood their inbox. By then, the damage is done — lost sales, damaged trust, and a scramble to figure out what happened.
- ✗You find out your site is down from a customer tweet instead of your monitoring tool
- ✗Free monitoring services check every 5-10 minutes, letting outages slip through the cracks
- ✗Alert fatigue from false positives makes your team ignore real incidents
- ✗No visibility into partial outages where the site loads but returns errors
Proactive Monitoring That Catches Issues in Real Time
CronJobPro sends HTTP requests to your website on a schedule you define — from every minute to every hour. When a request fails or returns an unexpected status code, it retries automatically before triggering alerts across your preferred channels.
Automatic Retries
Avoid false positives with configurable retry logic and exponential backoff that confirms an outage before alerting your team.
Multi-Channel Alerts
Get notified via email, Slack, or Discord the moment an issue is confirmed — no more checking dashboards manually.
Execution Logs
Review detailed HTTP response codes, response times, and headers for every check to diagnose issues faster.
How to Set It Up
- 1
Create a new cron job targeting your website URL
Enter your website URL as the endpoint. CronJobPro will send an HTTP GET request and check the response status code.
- 2
Set the monitoring frequency
Choose how often to check — every minute for critical sites or every 5 minutes for standard monitoring. Use the visual cron builder or type a cron expression.
- 3
Configure retry and alert settings
Set 2-3 automatic retries with exponential backoff to eliminate false positives. Add email, Slack, or Discord as alert channels.
- 4
Review execution history and optimize
Use the execution logs dashboard to spot patterns — slow response times, intermittent errors, or time-of-day issues.

Frequently Asked Questions
How quickly will I be notified if my website goes down?
CronJobPro can check your site as often as every minute. After automatic retries confirm the outage (typically 1-2 minutes), alerts fire immediately to all your configured channels.
Can I monitor multiple websites with different schedules?
Yes. Each cron job is independent — you can monitor your main site every minute, your blog every 5 minutes, and your staging server every 30 minutes.
How does CronJobPro avoid false positive alerts?
The automatic retry system with exponential backoff re-checks your site multiple times before triggering an alert. Only confirmed outages generate notifications.
What HTTP status codes are considered a failure?
By default, any response outside the 2xx range is treated as a failure. You can customize this in your job settings to accept specific codes like 301 redirects.
