The short version

  • 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; Pix4D split into separate products by job, so PIX4Dreact at $55 a month, PIX4Dfields at $111, PIX4Dmatic at $125 and PIX4Dmapper at $333 are different purchases rather than tiers
  • They diverge on capability: AGI STK covers Orbit analysis, Pix4D covers Photogrammetry.

Where each one falls short

Documented limitations, not opinions. Every one is a constraint you would hit in normal use.

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
  • Further capability is sold as separate add-on toolkits including TETK, the RF Channel Modeler and the STK Missile Toolkit
  • Distributing an application built on STK Engine to end users requires each of them to hold an Ansys STK Engine Runtime License
  • Free access is limited to students at accredited institutions and to time-limited trials
  • No price, minimum or cost driver is published for any STK tier

Pix4D

  • Split into separate products by job, so PIX4Dreact at $55 a month, PIX4Dfields at $111, PIX4Dmatic at $125 and PIX4Dmapper at $333 are different purchases rather than tiers
  • Subscription only, with monthly, yearly or three year cycles and no perpetual licence
  • No refunds, and cancellation only takes effect at renewal
  • Cloud processing is an add-on to the desktop subscriptions
  • Hardware scanning kit prices are quoted on request
