The short version

  • Only PostHog has a free tier, so it costs nothing to try first.
  • Each has a real cost: PostHog the free tier covers 1M events, 5K web session recordings and 2.5K mobile recordings per month before usage-based billing starts; 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
