The short version

  • Each has a real cost: OpenSCAD script-based workflow, not interactive design interface; 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: OpenSCAD covers Script-based modeling, Weka covers Classification.
  • Prices and features above were last checked on 30 August 2026.

Where each one falls short

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

OpenSCAD

  • Script-based workflow, not interactive design interface
  • Limited to constructive solid geometry and 2D extrusion modelling
  • Not suitable for artistic 3D modelling or computer animation
  • Complex build dependencies (Qt, CGAL, Boost)

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
