Cronitor free tier includes Cron job and uptime monitoring — free Hacker plan: 5 monitors, 5-minute check frequency, email… Not verified — our last read, on 2026-11-01, found a change we could not reconcile. Compare with 32 alternatives in Monitoring.
Subtypes in Monitoring: cron_monitor — waits for a scheduled job to check in and alerts on the absence of the check-in rather than on a failure it observed; uptime_check — polls a URL or host from outside your infrastructure on a fixed interval and alerts when it stops answering; it runs no code of yours; status_page — publishes a page your own users read to see whether your service is up; synthetic_check — runs a check you author — a scripted browser session, a multi-step API call, or an assertion on a response body — on a schedule from outside your infrastructure, and reports whether the behaviour it asserts still holds. We read that on 2026-09-01 from https://cronitor.io/pricing, where it says: “events free $10 /mo per 100,000 events Custom Synthetic browser checks × $1 /mo per 1,000 checks Custom Fastest check” How we use this.

No recorded pricing changes for Cronitor. We publish no change we refused to record, so treat the empty history as a statement about our records, not about this vendor's pricing.
How Cronitor compares against every one of the 32 we list, not against a selection of them. A surface with room for every member of a tied set may rotate their order. A surface with room for only some of them names none of them, because which ones it named would be the claim, and a claim seeded on the date is not the one we serve tomorrow. How we decide this.
