Where each one falls short

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

Apigee

  • The free evaluation is a sandbox limited to 60 days
  • Pay-as-you-go has no SLA available at all
  • Pay-as-you-go bills environments separately from API calls, with a Base environment costing $365 per month per region
  • The Base environment is capped at 50 QPS with an SLA of up to 99%
  • Standard API Proxy calls are billed at $20 per 1M calls up to 50M, and Extensible API Proxy calls at $100 per 1M calls up to 50M
  • API Analytics is a paid add-on at $20 per 1M API calls and cannot be bought on a Base environment
  • Advanced API Security is a paid add-on at $350 per 1M API calls and cannot be bought on a Base environment
  • Monetization is unavailable on pay-as-you-go and requires a subscription tier
  • Additional API proxy deployments beyond those included cost $0.04 per hour per region on a Comprehensive environment
  • Subscription tiers Standard, Enterprise and Enterprise Plus are quote only with no published price
  • Google Cloud networking charges for IP addresses, data transfer out and forwarding rules are billed on top of Apigee usage

Stainless

  • Starter and Pro plan prices are not published and require contacting the company.
  • The free plan caps APIs at 25 endpoints, which excludes larger production APIs.
  • Overage charges apply per SDK/endpoint/month once limits are exceeded, which can make costs unpredictable at scale.
