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

Encore

  • Limited language support (TypeScript and Go only)
  • Pro tier requires per-member subscription pricing
  • Additional resource costs beyond subscription for AWS/GCP provisioning

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
