The short version

  • Only Amazon Aurora has a free tier, so it costs nothing to try first.
  • Each has a real cost: Amazon Aurora aurora requires AWS ecosystem knowledge and integration with other AWS services; Firebolt compute billed per second on Arm-based processors; small instances still incur measurable costs during idle periods despite auto-stop
  • They diverge on capability: Amazon Aurora covers MySQL/PostgreSQL Compatible, Firebolt covers Sub-second Queries.
  • Prices and features above were last checked on 30 August 2026.
