The short version

  • Each has a real cost: Directus free permissive use of the self hosted product is limited to organisations under $5M annual revenue with fewer than 50 employees, so crossing either threshold turns a free dependency into a paid licence; Kustomize no packaging or distribution story, which is exactly what Helm charts provide
  • They diverge on capability: Directus covers REST API, Kustomize covers Overlay patching.

Where each one falls short

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

Directus

  • Free permissive use of the self hosted product is limited to organisations under $5M annual revenue with fewer than 50 employees, so crossing either threshold turns a free dependency into a paid licence
  • The free Core tier is a hard limit of 3 seats, 25 collections and 5 flows
  • The Team plan is $499 a month billed annually, or $599 monthly, with extra seats at $50 each
  • Team caps collections at 50, expandable to 100, and flows at 20

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
