CronAman

Cronaman is a cron job monitoring tool built for indie developers and small teams who need more than just "did it run?" alerts.

Most monitoring tools only check whether a ping arrived. Cronaman goes further with semantic ping payload assertions — you define what a successful response looks like, and Cronaman alerts you when your job runs but returns wrong data, empty results, or unexpected output.

Key features:

• Dead simple ping integration (GET /ping/:slug) with start and fail endpoints
• Semantic payload assertions to catch silent failures
• Flexible scheduling with cron expression support
• Alert channels: email, Slack, and webhooks
• Grace periods and alert thresholds to reduce noise
• Public status pages for your monitors
• Flat-rate pricing — no per-seat or per-monitor fees

Free plan: 3 monitors, email alerts. Pro plan ($15/mo): unlimited monitors, 1-minute frequency, Slack + webhook alerts.
