The short version

  • Only Pix4D has a free tier, so it costs nothing to try first.
  • Each has a real cost: Bentley iTwin Capture Modeler the rename from ContextCapture is more than cosmetic: licensing moved into Bentley's subscription and consumption model, and existing perpetual users should confirm what a renewal converts to before assuming continuity of 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
  • They diverge on capability: Bentley iTwin Capture Modeler covers Aerial triangulation, Pix4D covers Photogrammetry.
  • Prices and features above were last checked on 1 September 2026.

Where each one falls short

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

Bentley iTwin Capture Modeler

  • The rename from ContextCapture is more than cosmetic: licensing moved into Bentley's subscription and consumption model, and existing perpetual users should confirm what a renewal converts to before assuming continuity of cost.
  • Consumption-based entitlements make the cost of a large reconstruction hard to predict in advance, which is awkward when you are quoting a fixed-price deliverable to a client.
  • The desktop engine is Windows only and reconstruction is compute-hungry, so meaningful throughput needs either serious workstation hardware or paid cloud processing.
  • Bentley does not publish a plain rate card and pricing varies by region, reseller and existing agreement, so two firms buying the same thing can pay very different amounts.
  • Value compounds inside the Bentley ecosystem, and a firm whose design work happens in Autodesk or Esri tools pays for a positioning it will not use while getting the same mesh a cheaper standalone photogrammetry package would produce.

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
