The short version

  • Only CesiumJS 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.; CesiumJS the free Community tier does not permit commercial use
  • They diverge on capability: Bentley iTwin Capture Modeler covers Aerial triangulation, CesiumJS covers Core Functionality.
  • 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.

CesiumJS

  • The free Community tier does not permit commercial use
  • The cheapest commercial plan is $149 a month for an individual and $524 for a team
  • Team accounts are capped at 5 members on both the Commercial and Premium plans
  • Three separate quotas apply at once, being storage, monthly streaming and monthly reality modelling gigapixels, and exceeding any one of them constrains the account
  • Streaming is capped at 15 GB a month on the free tier

Answered from the vendors’ own pages

Bentley iTwin Capture Modeler: Is ContextCapture discontinued?

The name is. The product continues as iTwin Capture Modeler within Bentley's iTwin family.

CesiumJS: Is Cesium ion free for commercial use?

Cesium offers a free Cesium ion community account, but the page does not explicitly state whether the free tier is permitted for commercial use or if restrictions apply to business applications.

Bentley iTwin Capture Modeler: Does it still support a perpetual licence?

New buyers should expect subscription or consumption-based entitlements. Confirm the exact conversion path if you hold an older perpetual licence.

CesiumJS: What are the limits of the free Cesium ion community account?

The page only mentions that a free community account is available but does not disclose usage limits, storage quotas, or feature restrictions for the free tier.

Source
Bentley iTwin Capture Modeler: Can it process laser scan data as well as photographs?

Yes. It fuses point clouds with imagery in a single reconstruction.

CesiumJS: What do paid Cesium ion tiers cost?

The page does not provide specific pricing for paid tiers. It directs users to sign up for a free community account or contact Cesium directly for detailed pricing information.

Source
Bentley iTwin Capture Modeler: Do I need other Bentley software to use it?

No, output formats are usable elsewhere, but the commercial and workflow case is strongest if you already run MicroStation or OpenRoads.
