Healthchecks.io

Healthchecks.io is a monitoring service designed for teams managing cron jobs, background workers, and scheduled tasks across their infrastructure. It addresses the problem of silent failures by detecting when jobs don't run on their expected schedules and notifying users immediately. The platform works by assigning each monitored task a unique ping URL that the job must call during execution. Users configure timing parameters and can optionally define schedules using cron expressions. The dashboard displays the status of all monitored jobs with customizable labels and tags, while detailed event logs track ping history and alert records. A free tier supports up to 20 checks without requiring a credit card.
