The short version

  • Only CesiumJS has a free tier, so it costs nothing to try first.
  • Each has a real cost: CesiumJS the free Community tier does not permit commercial use; Global Mapper it is Windows only with no macOS or Linux build, so mixed-platform teams end up running a virtual machine and lose graphics performance on large point clouds
  • They diverge on capability: CesiumJS covers Core Functionality, Global Mapper covers Format breadth.
  • 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.

CesiumJS

  • Streaming 3D terrain, imagery and building data into web applicationsnot Global Mapper
  • Tiling and hosting large geospatial and reality capture datasetsnot Global Mapper

  • A geologist producing volumes, contours and cross sections from terrain data on a standalone office workstationnot CesiumJS

Where each one falls short

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

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

Global Mapper

  • It is Windows only with no macOS or Linux build, so mixed-platform teams end up running a virtual machine and lose graphics performance on large point clouds
  • The interface has grown by accretion over two decades and features are scattered across menus, so new users are slow to find capabilities that are already installed
  • Node-locked perpetual licences are tied to the machine identifier, so a hardware refresh or a failed workstation means a support request rather than a login on a new device
  • Multi-user and web publishing are weak relative to Esri or QGIS with a server stack, so it is a desktop analysis tool and not a platform for sharing data across an organisation
  • Published prices apply to North America and differ elsewhere, so buyers outside that market must go through a reseller and cannot rely on the listed figures for budgeting

Answered from the vendors’ own pages

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.

Yes. Blue Marble sells perpetual node-locked, floating, dongle and network licences that keep working after maintenance lapses.

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.

Global Mapper: What is the difference between Standard and Pro?

Pro is an add-on to a matching Standard licence and carries the lidar classification, feature extraction, Pixels to Points photogrammetry and advanced terrain tools.

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.

Global Mapper: Do I have to pay maintenance?

Only for the first year, which is included. After that it is optional; without it the software continues to run but you receive no upgrades or support.
