Tools | AsyncAPI Initiative for event-driven APIs

Discover various AsyncAPI tools to optimize your journey! These tools are made by the community, for the community. Have an AsyncAPI tool you want to be featured on this list? Then follow the procedure given in the Tool Documentation file, and show up your AsyncAPI Tool card in the website.
The following is a list of APIs that expose functionality related to AsyncAPI.
Explore APIs and companies with public AsyncAPI specifications.
Directory of asynchronous API specifications in AsyncAPI format.
This is code-first approach to generate AsyncAPI specification from Socket.IO server.
The following is a list of tools that generate AsyncAPI documents from your code.
The AsyncAPI.NET SDK contains a useful object model for AsyncAPI documents in .NET along with common serializers to extract raw OpenAPI JSON and YAML documents from the model.
The official continuation of LEGO.AsyncAPI.NET from the original author and maintainer. The SDK contains a useful object model for AsyncAPI 3.0 documents in .NET. Full JsonSchema and Avro support
Code-first AsyncAPI documentation generator and ui
Code-first AsyncAPI 3.0 document generation for Go: declare channels and operations as Go values, reflect payload schemas from your wire structs, validate against the embedded official meta-schema, and gate the committed document in CI.
A library that provides built-in support for generating AsyncAPI documents from minimal or controller-based APIs in ASP.NET Core, bringing the same developer experience as Microsoft.AspNetCore.OpenApi but for AsyncAPI specifications.

A powerful and easy-to-use Python framework for building asynchronous services interacting with event streams such as Apache Kafka, RabbitMQ and NATS.
This library helps to create AsyncAPI spec from your Go message structures. It uses reflection to translate Go structures in JSON Schema definitions and arrange them in AsyncAPI schema.
This tool stores modules, which simplifies interacting with AsyncAPI in jvm ecosystem.
AsyncApi code-first tools for c#. Generates document and view.
The Kotlin AsyncAPI project aims to provide convenience tools for generating and serving AsyncAPI documentation. The core of this project is a Kotlin DSL for building the specification in a typesafe way.
Utilize decorators to generate AsyncAPI document utilizing DTOs (similar to @nestjs/swagger) and a web UI.
A .NET SDK for the Async API specification. Automatically generates and serves AsyncAPI documents based on your code. Includes fluent-builders to create AsyncAPI documents from scratch, and provides a web-based GUI to browse generated documents.
Python-first Socket.IO runtime validation with Pydantic and code-first AsyncAPI contracts.
A simple, fast, and extensible async task queue framework, with built-in AsyncAPI 3.0 schema generation.
Saunter is an AsyncAPI documentation generator for dotnet. Generates (and hosts) an AsyncAPI schema document from your code.
This is code-first approach to generate AsyncAPI specification from Socket.IO server.
Automated documentation for async APIs built with Spring Boot. Like Springfox for AsyncAPI. Auto-generates an AsyncAPI document and a web UI.
Library for describing HTTP endpoints, and then interpreting them as a server, client, or documentation
Socket.IO solution with I/O validation that generates AsyncAPI specs and consumer contracts.
The following is a list of tools that generate code from an AsyncAPI document; not the other way around.
Generator is a tool that you can use to generate whatever you want basing on the AsyncAPI specification file as an input.
Generate payload models into Java, TypeScript, Go, etc, you name it, from AsyncAPI documents. This tool gives you full control over the models through high customization
Easily generate type-safe and async Python applications from AsyncAPI 3 specifications.
WebSocket framework for Django/FastAPI with AsyncAPI 3.0 spec generation and Python client generation from AsyncAPI schemas
Generate Go user and application boilerplate from AsyncAPI specifications. Can be called from `go generate` without requirements.
Generate Go user and application boilerplate from AsyncAPI specifications. Can be called from `go generate` without requirements.
This is a plugin designed to help developers automatizing the creation of code classes from YML files based on AsyncApi and OpenAPI. It is presented in 2 flavours Maven and Gradle
A plugin for generating and configuring nodes for Kafka, MQTT, AMQP, etc. automatically from an AsyncAPI specification.
A comprehensive PHP library providing annotations/attributes for the AsyncAPI 3.0.0 specification. This library enables you to define AsyncAPI specifications using modern PHP 8.3+ attributes with strict typing, PSR compliance, and support for all protocol bindings.
Generate Socket.IO TypeScript event interfaces from Pydantic-SocketIO AsyncAPI contracts.
Stop wasting time on manual code. Generate Payloads, parameters, headers, types, channel wrappers, and more from your AsyncAPI document! Works with Kafka, NATS, MQTT, event-source, AMQP, HTTP Client!
