CronAlarm
CronAlarm provides robust monitoring for cron jobs and scheduled tasks, alerting users when any issues arise. It offers critical insights into the performance and reliability of tasks, ensuring users are informed if jobs run too quickly, too long, or fail to run at the correct interval. With a simple setup, requiring only access to a URL—CronAlarm makes monitoring easy. Users can receive custom alerts through email, webhooks, or Slack, ensuring they stay updated on their task performance. CronAlarm offers a 7-day free trial with full feature access, plus the ability to monitor one job for free indefinitely, with no credit card required. CronAlarm has always used Coordinated Universal Time (UTC) for all alerts and reports in the CronAlarm dashboard and management interface. However, the ability for users to set a timezone preference has been one of our most requested features. This has been added to the CronAlarm platform.

Cronjob.de
Cronjob.de runs your cron jobs from the outside: enter a script's address, pick a schedule, and our servers call it on time – every minute, daily or on any crontab expression. No server, SSH or crontab access needed: the simple fix for shared hosting, WordPress (WP-Cron), shops and web apps.
Set-up takes seconds: paste your host's cron instructions or describe the schedule in plain words, and the AI fills in the job. Claude, ChatGPT and Cursor can manage your jobs via MCP.
Every call is logged with status and runtime. If a job fails, you get one alert per incident and an all-clear when it recovers – by email, Slack, Microsoft Teams, Discord or webhook. Cronjob.de also monitors websites and SSL certificates.
Run by a German company since 2003, servers in the EU, invoices with VAT and a GDPR data processing agreement. Up to five cron jobs are free for good; every new account starts with a 14-day trial of all features.

Ping Clock
Ping Clock monitors cron jobs, backups, scheduled tasks and background workers through heartbeat pings. Unlike uptime monitors that check services responding to requests, it can detect when a scheduled job stops running. Each job pings a unique URL when it runs, and missed pings trigger alerts. Set a period and grace time or a cron expression in any time zone. Start, success and fail pings show whether a job never ran, failed or hung, and the job can send its exit code. Email and Slack alerts are available on every plan, with Microsoft Teams, Discord and webhooks on Starter and higher. Pro adds run-duration tracking, log capture and an API. The Free plan includes 20 checks with no credit card required.
