The short version

  • Only Supabase has a free tier, so it costs nothing to try first.
  • Each has a real cost: Supabase free tier projects auto-pause after 1 week of inactivity; 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
