Bitwarden

  • File storage is capped at 5 GB on Premium and 5 GB personal plus 5 GB family on the Families plan

  • The Families plan is capped at 6 people, so a seventh member means moving to a Teams subscription at $4 per user per month

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
