The short version

  • Each has a real cost: Weka the package management system needs an internet connection to download and install packages, so an air-gapped install gets only the core distribution; Wireshark free and open source under the GNU GPL; downloadable without paying any license fee, no commercial tier
  • They diverge on capability: Weka covers Classification, Wireshark covers Deep packet inspection.
  • 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.

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

Wireshark

  • Free and open source under the GNU GPL; downloadable without paying any license fee, no commercial tier
