# Cronheart

> Cronheart is a heartbeat monitor for scheduled jobs. Each cron job, systemd timer or scheduler task pings its own URL when it runs, and Cronheart alerts by email, Telegram, Slack, Discord or webhook when a ping is late or reports a failure. Monitors can be created and managed over a REST API with a personal access token on every plan, the free one included.

## Docs
