Open source alternative to:

Healthchecks is an open-source monitoring service for cron jobs, background tasks, and scheduled processes.
Instead of actively checking your service, Healthchecks waits for periodic “pings” from your scripts or applications.
If a ping is late or missing, it triggers an alert so you know something went wrong.

Key Features

Flexible scheduling – Set custom check intervals and grace periods to match your job’s expected run time.
Multiple notification channels – Get alerts via email, Slack, Microsoft Teams, Telegram, Discord, webhooks, and more.
Failure and recovery alerts – Receive notifications when a job fails and when it resumes successfully.
Integration-friendly – Simple HTTP and email interfaces for easy integration into scripts and workflows.
Self-hosted or hosted – Run it on your own server or use the managed service at healthchecks.io.
API access – Manage checks, integrations, and status programmatically.

Healthchecks is especially useful for monitoring critical jobs like backups, report generation, and data imports—giving you peace of mind that your automation is running on schedule.
