AsyncAPI

AsyncAPI Specification

Adopt Foundation AsyncAPI Initiative, Linux Foundation Since 2017

Judgement: Adopt

The OpenAPI-equivalent for event APIs once you commit to documenting them.

Open-source standard for defining event-driven and message-based APIs across protocols like Kafka, AMQP, MQTT, WebSocket, and NATS.

Where OpenAPI describes synchronous request/response, AsyncAPI describes asynchronous channels. The two specifications are intentionally aligned in style.
