The short version

  • Each has a real cost: Intercom pricing is high and unpredictable with confusing per-seat, per-feature, and usage-based structure that makes cost estimation difficult; Kustomize no packaging or distribution story, which is exactly what Helm charts provide
  • They diverge on capability: Intercom covers AI-powered inbox, Kustomize covers Overlay patching.

Where each one falls short

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

Intercom

  • Pricing is high and unpredictable with confusing per-seat, per-feature, and usage-based structure that makes cost estimation difficult
  • API rate limited to 1,000 calls per minute, which may constrain integrations for high-volume data users
  • Does not support multiple language versions of knowledge base articles, requiring creation of duplicate articles for each language

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
