The short version

  • Only WhiteboxTools 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.; WhiteboxTools there is no vendor and no commercial support contract, so an organisation whose regulatory or client obligations require an answerable supplier cannot use it for that work no matter how good the algorithms are.
  • They diverge on capability: Correlator3D covers Aerial triangulation, WhiteboxTools covers Hydrological analysis.
  • 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.

Correlator3D

  • An aerial survey company processing large photographic blocks where per-project cloud credits would be more expensive than owning a licencenot WhiteboxTools
  • A national or regional mapping agency that needs software it can run offline on classified or restricted imagerynot WhiteboxTools
  • A drone service provider producing bare-earth terrain models for volumetrics and corridor mapping at high throughputnot WhiteboxTools
  • An organisation that wants a perpetual licence because a multi-year subscription cannot be justified against its capital budgeting rulesnot WhiteboxTools

WhiteboxTools

  • A hydrologist who needs depression breaching rather than filling on a large DEM, because filling destroys the drainage structure the model depends onnot Correlator3D
  • A forestry or environmental team processing airborne LiDAR into canopy height and terrain models without buying a point cloud licence per analystnot Correlator3D
  • A GIS developer embedding terrain analysis into a commercial product, where the MIT licence avoids the copyleft obligations of GRASS or SAGAnot Correlator3D
  • A university teaching geomorphometry where every student needs the full toolset on their own laptop at zero costnot Correlator3D

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.

WhiteboxTools

  • There is no vendor and no commercial support contract, so an organisation whose regulatory or client obligations require an answerable supplier cannot use it for that work no matter how good the algorithms are.
  • Maintenance depends on a single academic research group and effectively on one professor, which is a real continuity risk for anything embedded in a production pipeline for a decade.
  • It is command line first; the QGIS plugin and Python bindings help, but analysts who expect a graphical workflow with previews and undo find it unforgiving.
  • Documentation is a reference manual rather than a set of worked workflows, so knowing which of 450 tools to chain for a given problem requires domain knowledge the software does not supply.
  • Naming and behaviour overlap confusingly with the older Whitebox GAT, a separate GPL-licensed desktop GIS from the same group, and adopters regularly install or cite the wrong one.

Answered from the vendors’ own pages

Correlator3D: Can I still buy a perpetual licence?

Yes. $5,900 for a permanent licence and $6,400 for a permanent floating licence, each including a year of support and updates.

WhiteboxTools: Is WhiteboxTools free for commercial use?

Yes. It is MIT licensed, which permits commercial use and embedding without a copyleft obligation.

Correlator3D: What limits the standard licence?

Sensor resolution, up to 61 megapixels. Medium format, large format and satellite imagery need separately priced licences.

WhiteboxTools: Is there paid support?

No general commercial support contract is offered. Support is GitHub issues and community forums. Budget internal expertise instead.

Correlator3D: Is there a cloud version?

No. Processing runs on your own Windows workstation. SimActive offers a data processing service as an alternative to buying the software.

WhiteboxTools: Who maintains it?

Professor John Lindsay and the Geomorphometry and Hydrogeomatics Research Group at the University of Guelph, Canada.

Correlator3D: Does it handle satellite imagery?

Yes, under a separate satellite licence class quoted on request.

WhiteboxTools: How is it different from Whitebox GAT?

Whitebox GAT is an older GPL-licensed desktop GIS from the same group. WhiteboxTools is the newer Rust command line engine with a permissive licence. They are not the same product.

WhiteboxTools: Can I use it from QGIS?

Yes, through a plugin, and also from Python and R.
