Why AsyncAPI?

Improving the current state of Event-Driven Architectures (EDA)

  • Specification

    Allows you to define the interfaces of asynchronous APIs and is protocol agnostic.

  • Document APIs

    Use our tools to generate documentation at the build level, on a server, and on a client.

  • Code Generation

    Generate documentation, Code (TypeScript, Java, C#, etc), and more out of your AsyncAPI files.

  • Community

    We're a community of great people who are passionate about AsyncAPI and event-driven architectures.

  • Open Governance

    Our Open-Source project is part of Linux Foundation and works under an Open Governance model.

  • And much more...

    We have many different tools and welcome you to explore our ideas and propose new ideas to AsyncAPI.

What the experts are saying

  • Microservices underline the need for event-based communication in distributed architectures. AsyncAPI brings the richness of the REST API ecosystem to asynchronous APIs.

  • Event-driven APIs need love too! AsyncAPI brings the many benefits of a machine/human readable specification to these nuanced approaches.

  • Developers need to be able to quickly and consistently create event-driven applications that provide business value and react to customer needs in realtime. I can't count how many times I've heard developers ask for OpenAPI/Swagger style tools for the asynchronous and event driven world, and that is exactly what the AsyncAPI initiative is making a reality.
