The short version

  • Each has a real cost: Asyncapi complex to implement and debug asynchronous operations due to their non-linear and concurrent nature; Gravitee the entry paid API management tier is $2,500 a month and includes a single production gateway
  • They diverge on capability: Asyncapi covers API Specification, Gravitee covers API Gateway.

Where each one falls short

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

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

Gravitee

  • The entry paid API management tier is $2,500 a month and includes a single production gateway
  • Event management is priced separately, starting at $1,250 a month for the Comet tier
  • Tiers are gated on gateway and broker counts, so scaling horizontally means moving tier rather than paying incrementally
  • Data logging masking and other enterprise features are withheld from the lowest paid tier
  • 24/7 support requires the top Universe tier
