The short version

  • Only AWS API Gateway has a free tier, so it costs nothing to try first.
  • Each has a real cost: AWS API Gateway rEST APIs cost $3.50 per million calls against $1.00 for HTTP APIs, so the older and more featureful type is three and a half times dearer; Kustomer pricing not published; requires customised sales assessment and quote for exact costs
  • They diverge on capability: AWS API Gateway covers REST APIs, Kustomer covers Unified customer view.
