Editorial interest 79/100 Selection signal · not a rating of the site

A monitoring tool for cron jobs, backups, n8n workflows, and GitHub Actions that alerts on late check-ins or output counts outside an expected range.

Landing page captured for the 2026-09-23 issue.

For: Operators of cron jobs and workflow automations
Worth noticing: Each check-in can report a row, file, or invoice count, with an expected range that catches zero-output runs.

Field notes

Setup uses one outbound request from the job already running, with no agent installation or access to the user's systems described. The examples pass a count in a URL parameter and compare it with a configured range. For agencies, the page describes grouping checks by client and sharing read-only status links that include an incident timeline.
