Where each one falls short

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

Fig

  • Shut down on 1 September 2024. Amazon acquired Fig in August 2023 and folded it into Amazon Q Developer, which now carries the terminal autocomplete
  • The standalone desktop app is no longer available or supported
  • The completion specs remain open source on GitHub, but the product that consumed them is gone

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
