Cron Job Monitoring
Free for Hobby Use
Healthchecks.io is free for hobby use, open source projects, and non-profits.
Healthchecks.io is an online service for monitoring regularly running tasks such as cron jobs. It uses the Dead man's switch technique: the monitored system must 'check in' with Healthchecks.io at regular, configurable time intervals. When Healthchecks.io detects a missed check-in, it sends out alerts. The service is trusted by thousands of developers and teams for its reliability and ease of use.
