Healthchecks

Description

Healthchecks is an open-source cron job and background task monitoring service, and a self-hosted alternative to Cronitor and Dead Man's Snitch. Each monitored job pings a unique Healthchecks URL after it runs; Healthchecks tracks the expected schedule and raises an alert the moment a ping is late, missing entirely, or reports a failure exit code. Checks can be grouped into projects and tagged, given cron or "every N minutes" schedules with grace periods, and monitored on a public or private status page. Alerts go out over email, Slack, Telegram, PagerDuty, Opsgenie, webhooks, and 25+ other integrations, so silent cron and backup failures get noticed before they become incidents.
