The short version

  • Only Postman has a free tier, so it costs nothing to try first.
  • Each has a real cost: Checkmk pricing is metered per service (each individual metric or sensor monitored) rather than per host, so cost scales with monitoring depth, not just server count; Postman free plan limited to single user as of March 1, 2026, making it unsuitable for teams without paid plans
