Where each one falls short

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

Git

  • Licensed under GNU GPL version 2.0 as stated on git-scm.com/about; as open source software it has no paid tier or vendor price to compare
  • Git is a command line tool by design; graphical workflows and hosted collaboration depend entirely on third party GUIs and hosting services layered on top, per git-scm.com/about

Kustomize

  • No packaging or distribution story, which is exactly what Helm charts provide
  • Deeply nested overlays become hard to follow, and reasoning about the final output requires building it
  • No release lifecycle: nothing tracks what is installed or supports rollback the way Helm does
  • Patch syntax is fiddly for anything beyond simple field replacement
