The short version

  • Only Calendly has a free tier, so it costs nothing to try first.
  • Each has a real cost: Calendly the free plan allows one event type and one calendar connection, so it cannot handle different meeting formats; 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: Calendly covers Calendar sync, Firebolt covers Sub-second Queries.
