Where each one falls short

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

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

PhpStorm

  • Requires an ongoing paid subscription with no free tier for commercial use.
  • Heavier and slower to start than lightweight code editors.
  • Some advanced framework-specific tooling requires additional configuration or plugins.
  • Renewal pricing rises for lapsed subscriptions after the grace period.
