The short version

  • Each has a real cost: KNIME the free Analytics Platform runs locally only, so anything shared or scheduled requires a paid Hub; 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: KNIME covers Visual workflows, Weka covers Classification.
  • Prices and features above were last checked on 30 August 2026.
