  • AI credits needed for integrated AI features
  • No mention of free trial for commercial use

Kustomize

  • No packaging or distribution story, which is exactly what Helm charts provide

  • 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
