the prompt
Build me a cron-job monitor like Cronitor / Healthchecks. Requirements:

- Each monitored job gets a unique ping URL (/ping/:uuid). The job's crontab
  line just appends `&& curl -fsS <url>` · document this.
- Define jobs in SQLite via a basic-auth /admin page: name, expected period
  (e.g. every 60 min) and grace time. Store every ping with timestamp.
- A scheduler loop checks each job: if now > last_ping + period + grace, the job
  is LATE → send one alert webhook (Discord/Slack/Telegram, URL in .env) with
  the job name and how late it is. Alert again on recovery. No alert spam ·
  one per state change.
- /admin dashboard: each job as a row with green/amber/red status dot, last ping
  time ("7 min ago"), and a 24h ping histogram as inline SVG.
- Support /ping/:uuid/fail for explicit failure reports with an optional body
  shown in the alert.
- Python or Node, single process, systemd unit included.

questions
Can AI replace Cronitor?

Yes. A competent AI coding agent (Claude Code, Codex, Cursor) can build a usable personal Cronitor replacement in one session with the prompt on this page. It runs on your own machine or server with no subscription.

How much does Cronitor cost?

Cronitor costs about $10/month (paid plan, checked 2026-07-29), which is $120 per year. That's what you save by replacing it with one prompt.

What do I lose by replacing Cronitor?

Honestly: their status pages and team features; alert routing (SMS, PagerDuty); cron expression insights. If any of those are load-bearing for you, keep paying.

Is there an open-source alternative to Cronitor?

Yes — Healthchecks (excellent open-source cron monitoring). Using prior art is also a valid exit; the prompt is for when you want it exactly your way.
