Gonewatch

Gonewatch is heartbeat monitoring for expected work — cron jobs, nightly backups, and scheduled GitHub Actions. It is not uptime monitoring of a public URL. You create a monitor with a fixed time of day or a rolling interval, plus a grace window. After the job succeeds, POST to a unique heartbeat URL (curl, Node, Python, or uses: gonewatch/heartbeat@v1). If that ping never arrives, Gonewatch marks the monitor Down and emails you. Paid plans add Slack. A failed job should not ping, so a red X on GitHub or a failed cron stays a miss. GitHub already emails failed workflow runs. It does not email a schedule that never started. Silence is the alert. No agent on the box. Free plan with 3 monitors and email alerts, no credit card. Basic starts at $9/month. Website: https://www.gonewatch.com GitHub Action: https://github.com/marketplace/actions/gonewatch-heartbeat
