The short version

  • Only Apple Calendar has a free tier, so it costs nothing to try first.
  • Each has a real cost: Apple Calendar offline sync via USB has reported issues with duplicated events when syncing between macOS and iOS; 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: Apple Calendar covers Event management, Firebolt covers Sub-second Queries.
