Monitoring & Observability
Cron job, heartbeat and uptime monitoring. Free Hacker plan with 5 monitors and a status page.
Get an alert when a job fails, runs late or never runs. Cronitor monitors cron jobs, scheduled tasks, heartbeats, uptime checks and APIs, and alerts you when a job fails, runs late or never runs. Its Hacker plan is $0 and the pricing page calls it free forever: 5 monitors, email and Slack alerts, a basic status page with 50 subscribers, one dashboard user, 5-minute checks and 100,000 web analytics and error events. SMS alerts and premium integrations are paid. The Business plan has no base fee and charges $2 a month per monitor and $5 a month per user, with a 14-day free trial. Capterra reviewers praise easy setup and quick support, though many of those reviews were vendor-referred with an incentive.

Five monitors disappear fast. A few cron jobs, a backup and a heartbeat uses them up, and the next monitor costs $2 a month on Business once you move off Hacker. The free plan has one dashboard user, 5-minute checks and no SMS. Alerts go to email and chat tools like Slack, and anything that pages a person, such as PagerDuty or SMS, needs Business. Cronitor's pricing page says the Business plan has a 14-day free trial. The page does not say whether the Hacker plan needs a card, and I did not find a commercial use clause.
No base fee or minimum. 14-day free trial, 30-second checks, all 11 alert integrations, SMS and on-call alerts, 12-month retention and unlimited API requests. Example from the page: 20 monitors and 3 users is $55 a month.
Branded status page $25 a month per page, private page $50 a month per page, SAML single sign-on +$5 a month per user, web analytics $10 a month per 100,000 events and synthetic browser checks $1 a month per 1,000 checks.
Annual invoice billing with custom features and integrations, a dedicated engineer and priority support.
Yes. Hacker is $0 free forever with 5 monitors, email and Slack alerts, a basic status page and one dashboard user.
$2 a month per monitor and $5 a month per user, with no base fee. There is a 14-day free trial.
No. SMS alerts and on-call integrations are Business features.
Many are labeled vendor referred with an incentive. One I saw was non-incentivized and praised easy setup and a generous free tier.
Capterra reviewers describe integrating through the CLI or manually with simple requests. Check the docs for your scheduler.
Pricing page read. Capterra and Reddit read as excerpts; most visible Capterra reviews were vendor-referred and are labeled that way. Card requirement and commercial use not confirmed.
