The short version

  • Only TimescaleDB has a free tier, so it costs nothing to try first.
  • Each has a real cost: TimescaleDB inherits PostgreSQL write path limitations, creating a ceiling on ingestion throughput; Knack plans are priced by number of records and objects rather than users, ranging from $110 to $300 per month as data volume grows
