The short version

  • Each has a real cost: Spring Cloud Gateway released under the Apache 2.0 license, free and open source with no commercial tier; Asyncapi complex to implement and debug asynchronous operations due to their non-linear and concurrent nature
  • They diverge on capability: Spring Cloud Gateway covers Routing, Asyncapi covers API Specification.

Both are used for api development, api gateway, api testing, api documentation, microservices, on those jobs the choice comes down to price and fit rather than capability.

Where each one falls short

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

Spring Cloud Gateway

  • Released under the Apache 2.0 license, free and open source with no commercial tier

Asyncapi

  • Complex to implement and debug asynchronous operations due to their non-linear and concurrent nature
  • Keeping AsyncAPI documents up to date is challenging as systems evolve
  • Tracing and debugging asynchronous operations is more difficult than synchronous request-response patterns
