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

Monday.com

  • Expensive at scale with 3-seat minimum and costs increasing quickly with team size
  • Limited free plan with only 2 users and 3 boards
  • Mobile app provides reduced functionality compared to web version
  • Email CC/BCC limitations for looping in stakeholders without full board access
  • WorkForms can only create new items, not update existing ones
