FastStream
An asynchronous Python framework for building services that interact with Apache Kafka, RabbitMQ, NATS, and Redis event streams.
What is FastStream?
FastStream is an asynchronous Python framework for building services that interact with event streams like Apache Kafka, RabbitMQ, NATS, and Redis. It simplifies writing producers and consumers by handling parsing, networking, and documentation generation automatically, making it easier to develop streaming microservices.
Python developers building asynchronous microservices that need to process data from message queues or event streams, especially those working with Kafka, RabbitMQ, NATS, or Redis.
Developers choose FastStream for its easy-to-use API, automatic AsyncAPI documentation, built-in serialization with Pydantic/Msgspec, and seamless integration with multiple message brokers, reducing boilerplate and accelerating development.
Overview
FastStream is a powerful and easy-to-use asynchronous Python framework for building asynchronous services interacting with event streams such as Apache Kafka, RabbitMQ, NATS, MQTT and Redis.
