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; Zimpler pricing is not published and is set by industry and risk profile, so smaller merchants cannot benchmark a quote and often discover they are paying well above a general-purpose provider.
  • They diverge on capability: AWS API Gateway covers REST APIs, Zimpler covers Bank payments.
  • Prices and features above were last checked on 1 September 2026.

Where each one falls short

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

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
  • Data transfer out is charged at $0.09 per GB on top of request pricing
  • WebSocket APIs bill connection minutes as well as messages, at $0.25 per million minutes
  • Private APIs avoid data transfer charges but incur AWS PrivateLink costs instead
  • The developer portal is $125 a month, with additional portal products at $12.50 each
  • The free tier lasts 12 months rather than being ongoing

Zimpler

  • Pricing is not published and is set by industry and risk profile, so smaller merchants cannot benchmark a quote and often discover they are paying well above a general-purpose provider.
  • As a payment facilitator carrying merchant risk, it declines or offboards merchants on risk grounds, which makes it a dependency you cannot assume will persist.
  • Its strength is concentrated in the Nordics, and coverage in southern and eastern Europe is thinner than pan-European account-to-account specialists.
  • Revenue concentration in iGaming ties the provider to a sector under constant regulatory change, so licence changes in one market affect the supplier as well as the merchant.
  • Bank transfers have no chargeback protection, so disputes are handled commercially and consumers used to card protections may resist the payment method.
