The short version

  • Each has a real cost: CloudCompare the project is administered by its creator in his spare time while he holds a full-time job elsewhere, so an organisation building a monitoring programme on it depends on one person with no obligation to continue; Weka the package management system needs an internet connection to download and install packages, so an air-gapped install gets only the core distribution
  • They diverge on capability: CloudCompare covers Cloud to cloud distance, Weka covers Classification.
  • 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.

CloudCompare

  • The project is administered by its creator in his spare time while he holds a full-time job elsewhere, so an organisation building a monitoring programme on it depends on one person with no obligation to continue
  • There is no commercial support contract from anyone, so a defect that blocks a deliverable is resolved by a GitHub issue and community goodwill rather than by an agreement
  • Processing is single machine and memory bound, so very large aerial lidar collections must be tiled manually and large jobs are limited by the workstation rather than scaled out
  • The interface is unforgiving and organised around the underlying data structures rather than around tasks, so competent surveyors routinely take weeks to become productive
  • Plugins vary widely in maintenance, and several useful ones originated in research projects that have since ended, so a workflow built around a specific plugin can break at the next release

Weka

  • The package management system needs an internet connection to download and install packages, so an air-gapped install gets only the core distribution
  • Weka is split into a stable 3.8 branch that receives only bug fixes and compatibility-safe upgrades and a 3.9 development branch that may receive features that break compatibility
  • Weka requires a 64-bit Java VM; the bundled installers ship Bellsoft OpenJDK 25 per platform and architecture

Questions people ask

Is CloudCompare or Weka better?
Neither clearly leads. CloudCompare starts at Free and Weka at Free, and user ratings are close enough to be indistinguishable. Choose on capability and platform support.
Which is cheaper, CloudCompare or Weka?
CloudCompare starts at Free and Weka at Free.
Does CloudCompare or Weka run on more platforms?
CloudCompare runs on Windows, macOS, Linux. Weka runs on Linux, Mac, Windows.
Can I use CloudCompare for free?
Both have a free tier, so you can try either at no cost before committing.
What is CloudCompare best used for?
CloudCompare is most often used for a monitoring engineer comparing quarterly laser scans of a retaining wall to quantify movement without buying a proprietary deformation package, a heritage team registering dozens of terrestrial scans of a building into a single cloud before meshing, a geomorphologist measuring erosion between two drone-derived surfaces of a river bank, a survey technician cleaning and subsampling a scan before delivering it to a client whose software cannot handle the full density. Of those, a monitoring engineer comparing quarterly laser scans of a retaining wall to quantify movement without buying a proprietary deformation package and a heritage team registering dozens of terrestrial scans of a building into a single cloud before meshing are not what Weka is typically brought in for.
What can CloudCompare do that Weka cannot?
CloudCompare covers Cloud to cloud distance, Cloud to mesh distance, Registration, Segmentation and cleaning. Weka covers Classification, Regression, Clustering, Association rules.

Answered from the vendors’ own pages

CloudCompare: Who maintains CloudCompare?

Daniel Girardeau-Montaut, its creator, administers it in his own time alongside a full-time engineering job, with contributions from a community of users and research groups.

Weka: What is the cost of Weka software?

Weka is provided at no cost as open-source software released under the GNU General Public License, making it freely available for download and use.

Source
CloudCompare: Can I buy support?

No. There is no vendor and no commercial support offering. Some geospatial consultancies know it well and can be hired, but they are not contracted to support the software itself.

Weka: Are there commercial licensing options available?

Yes, the project offers information about commercial licenses for organizations requiring non-GPL terms, which can be found in their commercial applications documentation.

Source
CloudCompare: Is it suitable for commercial deliverables?

It is widely used for them. The licence permits it and the algorithms are well regarded. The risk is operational, not legal: no support and no roadmap commitment.

Weka: What support resources are available to users?

Multiple support avenues exist including comprehensive documentation, frequently asked questions, dedicated help resources, and access to courses for learning the platform.

Source
CloudCompare: Can it handle a full aerial lidar survey?

Not in one piece. It is memory bound on a single machine, so large collections need tiling or a dedicated lidar pipeline such as PDAL.

Weka: Is source code access provided?

Yes, developers have full access to source code through the Git repository, along with development documentation and code credits for contributors.
