The short version

  • Each has a real cost: Asyncapi complex to implement and debug asynchronous operations due to their non-linear and concurrent nature; Sanity free plan limited to 10,000 documents and 100GB assets
  • They diverge on capability: Asyncapi covers API Specification, Sanity covers Content API.

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

Sanity

  • Free plan limited to 10,000 documents and 100GB assets
  • Free plan supports only public datasets
  • Growth plan capped at 50 seats maximum
  • Private datasets, scheduled drafts, and comments/tasks require paid plans
