The short version

  • Only Asyncapi has a free tier, so it costs nothing to try first.
  • Each has a real cost: Asyncapi complex to implement and debug asynchronous operations due to their non-linear and concurrent nature; Celigo prices are not published on any of the three editions
  • They diverge on capability: Asyncapi covers API Specification, Celigo covers App integration.

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

Celigo

  • Prices are not published on any of the three editions
  • Billed on endpoints and flows, so the cost is driven by how many systems you connect rather than by volume through them
  • API Builder, lookup caching and a sandbox all require the Professional edition
  • Single sign-on is optional on Standard and included from Professional up
  • Unlimited endpoints and the full governance features are Enterprise only
