The short version

  • 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; Microsoft Power Automate free plan limited to 750 flow runs/month and standard connectors only; premium connectors require paid plans
  • They diverge on capability: AWS API Gateway covers REST APIs, Microsoft Power Automate covers Automated flows.

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

Microsoft Power Automate

  • Free plan limited to 750 flow runs/month and standard connectors only; premium connectors require paid plans
  • Not suitable for long-running workflows; can fail unexpectedly without warning
  • Limited to simple linear logic; fails with complex workflows involving multiple stakeholders
  • Tasks cannot automate at scale when requiring more than approximately 60 users

Answered from the vendors’ own pages

Microsoft Power Automate: Is Power Automate included with Microsoft 365?

Yes. If you have an eligible Microsoft 365 subscription, you can use Power Automate at no extra cost for flows relying only on standard connectors (SharePoint, Outlook, Teams). Premium connectors (Salesforce, SAP, Oracle) require paid plans.

Source
Microsoft Power Automate: How many flow runs are allowed on the free plan?

Power Automate's free tier (included with Microsoft 365) is limited to 750 flow runs per month and standard connectors only. Out of 900+ total connectors, the free plan only includes Microsoft ecosystem apps and limited third-party apps.

Source
Microsoft Power Automate: What's the difference between Premium and Process plans?

Premium ($15/user/month) provides attended automation with cloud flows and standard RPA. Process plan ($150/bot/month) enables unattended automation where bots run without human intervention on virtual machines for high-volume, repetitive tasks.

Source
Microsoft Power Automate: Does Power Automate support long-running workflows?

No. Power Automate is not suitable for long-lasting workflows because they can run without warning and fail unexpectedly. The platform is built for linear, branching logic (if-then) rather than complex, multi-step business processes involving multiple stakeholders.
