Healthchecks
Healthchecks is an open-source cron job and background task monitoring service written in Python and Django. It listens for HTTP pings from your scheduled jobs and sends alerts when a ping is late or missing, giving you a simple, self-hosted safety net for every cron job, backup script, and background task you rely on.
Key Features
- Dead-man’s switch monitoring — Each check expects a periodic ping; if it doesn’t arrive on time, Healthchecks alerts you.
- Flexible notification channels — Email, Slack, Telegram, Discord, webhooks, and 40+ other integration options.
- Grace periods and schedules — Configure cron expressions or simple intervals with per-check grace windows.
- Detailed ping history — View a timeline of every ping with response codes and body size for each check.
- Status pages — Publish public or private status pages showing the health of your services.
- Simple ping URLs — Each check has a unique URL; integrate in seconds from cron, scripts, or monitoring tools.
- Self-hosted — Runs on a single Docker container or bare metal; no external monitoring vendor required.
Why Use Healthchecks?
Silent cron failures are one of the sneakiest problems in server administration — jobs can fail for weeks without anyone noticing. Healthchecks gives you a free, self-hosted way to know the moment a scheduled job stops running, so you fix problems before users do.
Use Cases
- Monitoring cron jobs, backups, and database dumps
- Watching scheduled reports, syncs, and data imports
- Liveness checks for long-running background workers
- Team visibility through shared projects and status pages
