  • Only QuestDB has a free tier, so it costs nothing to try first.
  • Each has a real cost: Knack plans are priced by number of records and objects rather than users, ranging from $110 to $300 per month as data volume grows; QuestDB open-source edition lacks high-availability, distributed architecture, and enterprise security features
