The short version

  • Only Microsoft Azure API Management has a free tier, so it costs nothing to try first.
  • Each has a real cost: Microsoft Azure API Management prices are not shown on the pricing page itself; every tier renders as a placeholder and routes to the calculator or sales; Lambda no free tier or trial, requiring immediate commitment for testing
  • They diverge on capability: Microsoft Azure API Management covers API Gateway, Lambda covers Superclusters.
  • Prices and features above were last checked on 30 August 2026.

Microsoft Azure API Management

  • Prices are not shown on the pricing page itself; every tier renders as a placeholder and routes to the calculator or sales
  • Two parallel generations of tiers, classic and v2, so the choice is which lineage before which size
  • The Developer tier is explicitly not for production
  • Self-hosted gateways and workspace gateways are charged separately from the service

Lambda

  • No free tier or trial, requiring immediate commitment for testing
  • Single-tenant Superclusters require custom pricing discussions
  • Pricing complexity across multiple GPU types and cluster sizes
  • Less suitable for experimentation or small teams with tight budgets
