The short version

  • Only Pix4D has a free tier, so it costs nothing to try first.
  • Each has a real cost: Correlator3D the standard licence caps at 61 megapixel sensors, so an operator moving to a medium or large format camera has to buy a different and separately quoted licence rather than paying an upgrade fee.; 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: Correlator3D covers Aerial triangulation, Pix4D covers Photogrammetry.
  • Prices and features above were last checked on 1 September 2026.

What people use each for

The jobs each tool is most often brought in to do.

Where each one falls short

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

Correlator3D

  • The standard licence caps at 61 megapixel sensors, so an operator moving to a medium or large format camera has to buy a different and separately quoted licence rather than paying an upgrade fee.
  • It is Windows desktop only with no cloud processing option, so throughput is bounded by the workstation and GPU you buy, and there is no way to burst capacity for one large job.
  • There is no collaboration layer, client portal or field application, so deliverable sharing, review and version control all have to be handled by other software.
  • The interface and workflow are built for photogrammetry specialists; an occasional drone operator will find the learning curve steeper than a consumer-oriented mapping package.
  • The perpetual licence includes only one year of support and updates, and staying current afterwards means paying maintenance, so the headline $5,900 is not the whole long-term cost.

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
