Where each one falls short

Documented limitations, not opinions. Every one is a constraint you would hit in normal use.

Healthchecks

  • Free tier limited to 20 jobs, restricting scale for small teams
  • Requires explicit ping integration into each job
  • No workflow orchestration or job scheduling capabilities
  • SMS and phone credits consumed separately on paid plans
  • Limited to ping-based detection without deep job introspection

Prometheus

  • Not suitable for per-request billing as collected data lacks 100% accuracy
  • Hard limit on scrape body size; large responses cause scrape failure
  • Per-scrape sample limit enforced; exceeding limit marks targets as failed
  • Not designed for long-term durable storage; optimised for metrics collection
