The short version

  • Only AGI STK has a free tier, so it costs nothing to try first.
  • Each has a real cost: AGI STK sTK is sold as a ladder of separate licences, STK Pro, STK Premium Air, STK Premium Space and STK Enterprise, so mission areas are gated behind different products; EFB Pro aircraft type support is limited to a published list on CAVU's own site; adding a new aircraft type requires contacting CAVU directly rather than self-service configuration
  • They diverge on capability: AGI STK covers Orbit analysis, EFB Pro covers Flight planning.
