The short version

  • Only MotherDuck 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; MotherDuck the free Lite plan caps compute at 10 hours per month, which limits it to light or hobbyist workloads.
