The short version

  • Each has a real cost: Chef priced per node per year, at $59 on Business and $189 on Enterprise, so cost scales with fleet size rather than with team size; Kustomize no packaging or distribution story, which is exactly what Helm charts provide
  • They diverge on capability: Chef covers Recipes, Kustomize covers Overlay patching.
  • Prices and features above were last checked on 30 August 2026.

Where each one falls short

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

Chef

  • Priced per node per year, at $59 on Business and $189 on Enterprise, so cost scales with fleet size rather than with team size
  • Tripling the price between the two published tiers puts compliance and audit features well above basic automation
  • Enterprise Plus and every self managed deployment are custom quoted with no published price

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
