AsyncAPI has emerged as a complementary standard to OpenAPI, specifically designed for describing event-driven systems, which are increasingly popular in data streaming and IoT applications. Unlike the request/response pattern of OpenAPI, AsyncAPI accommodates data streams, queues, and brokers, facilitating the flow of data between systems through technologies like Apache Kafka, RabbitMQ, and MQTT. At Redocly, both OpenAPI and AsyncAPI are integrated into their systems, and the Redocly CLI tool supports AsyncAPI, providing features such as linting with customizable rules and bundling capabilities to streamline the creation and maintenance of API descriptions. These features make it easier to decouple and scale systems by ensuring data can be efficiently integrated and managed across different components.
