The short version

  • Each has a real cost: HashiCorp Vault policies are written in HCL with no graphical user interface for policy management or editing; 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: HashiCorp Vault covers Secret storage, Weka covers Classification.
