**APIs profiled:** 8

AsyncAPI is a Linux Foundation project that improves the state of event-driven architectures by providing an open specification and tooling ecosystem for defining asynchronous and event-driven APIs. It enables developers to document, validate, generate code, and manage message-driven APIs across protocols including Kafka, MQTT, WebSocket, AMQP, and others. The AsyncAPI specification serves as the industry standard for describing asynchronous messaging interfaces, similar to how OpenAPI serves REST APIs.
