  • Only AGI STK has a free tier, so it costs nothing to try first.
  • Each has a real cost: PFPX Flight Planning the Internet Archive's capture of pfpx.com on 7 December 2018 carried the vendor's own notice that 'The URL of the PFPX homepage has changed to www.flightsimsoft.com'; the 2021 capture of flightsimsoft.com confirms PFPX (Professional Flight Planner X) is sold by FSS GmbH alongside a second product, TOPCAT, though the linked Pricing page was not itself archived.; 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
  • They diverge on capability: PFPX Flight Planning covers Flight planning, AGI STK covers Orbit analysis.
