The Linux Foundation has announced it will host the AsyncAPI Initiative. AsyncAPI is a specification and a suite of open source tools that work with asynchronous APIs and event-driven architectures.
It is the fastest-growing API specification according to a recent developer survey, tripling in production usage from 2019 to 2020.
Founding sponsors of the AsyncAPI Initiative include Ably Realtime, Apideck, Bump, IQVIA Technologies, Slack, Solace, and TIBCO, and AsyncAPI recently announced a partnership with Postman. Today, AsyncAPI is in production at Adidas, PayPal, Salesforce, SAP, and Slack, among other enterprise environments.
AsyncAPI helps unify documentation automation and code generation, as well as managing, testing, and monitoring asynchronous APIs. It provides language for describing the interface of event-driven systems regardless of the underlying technology and supports the full development cycle of event-driven architecture.
The event-driven AsyncAPI is considered a sister project of the OpenAPI Initiative, which is focused on synchronous REST communication and is also hosted by Linux Foundation.
