Cronitor vs Healthchecks.io: which cron monitor fits in 2026?
Cronitor and Healthchecks.io are the two names that dominate cron-job monitoring. One is a commercial suite that grew from cron into uptime and synthetics; the other is a beloved open-source single-purpose service. Here is the honest referee’s view.
The referee’s verdict
Cronitor or Healthchecks.io?
Both vendors’ plan details verified on cronitor.io/pricing and healthchecks.io/pricing on August 21, 2026. Plans can change at any time.
- Pick Cronitor when
- You want cron telemetry, not just liveness: job durations, captured output, 30-second checks on paid plans, plus uptime checks, synthetic browser checks, and status pages in the same account — and usage pricing ($2/monitor/month) suits your fleet size.
- Pick Healthchecks.io when
- You want the simplest reliable dead-man’s-switch, self-hosting rights (BSD license), or the most free checks: 20 free vs Cronitor’s 5, a flat $20/month for 100 checks, and the Business plan free for open-source projects and nonprofits.
- Where PageLantern fits
- PageLantern fits when cron monitoring is one need among several: heartbeat checks with grace windows sit beside website uptime, API assertions, SSL and domain expiry, DNS, and TCP checks, feeding the same incidents and status pages — so a small team runs one tool instead of a cron monitor plus an uptime monitor.

FAQ
Frequently asked questions
Is Cronitor or Healthchecks.io better for cron job monitoring?
Healthchecks.io is the value and simplicity pick: 20 free checks, flat $20/month for 100, open source and self-hostable. Cronitor is the depth pick: job output and duration capture, faster checks, and uptime/synthetics in the same product on $2/monitor usage pricing. As of August 2026, five paid monitors on Cronitor already costs $10/month — cross-check your fleet size against the flat plans.
Can I self-host either of them?
Healthchecks.io, yes — it is BSD-licensed and commonly self-hosted, which also lets it watch jobs inside private networks. Cronitor is hosted-only. PageLantern is also hosted-only, so if self-hosting is a hard requirement, Healthchecks.io is the answer.
When would PageLantern beat both?
When cron checks are one item on a longer monitoring list. PageLantern Free includes 15 monitors spanning heartbeat, HTTP, API-assertion, SSL-expiry, domain-expiry, and TCP checks with a status page; neither Cronitor’s free tier (5 monitors) nor Healthchecks.io (cron only) covers that spread. PageLantern does not capture job output or duration metrics, so pure cron telemetry still favors Cronitor.
