Where each one falls short

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

Northflank

  • Pricing complexity with multiple rate dimensions
  • GPU costs can be expensive for large-scale deployments
  • Learning curve for Kubernetes concepts

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
