FastKafka – A Free Open-Source Python Library for Building Kafka-Based Services

A few months back, we released FastKafka, a free and open-source framework under the Apache 2 license that simplifies the process of writing producers and consumers for Kafka topics. Inspired by FastAPI, FastKafka uses the same paradigms for routing, validation, and documentation, making it easy to learn and integrate into your existing projects. The latest version adds support for newly released Pydantic v2.0, making it significantly faster.

With FastKafka, you can quickly prototype and develop high-performance Kafka-based services with minimal code. And, because it’s open-source, you can use it in your projects for free and contribute to its development if you’d like.

If you are working with streaming data, please test it and give us feedback for making it better. Visit the GitHub repository to get started, and don’t hesitate to reach out to the FastKafka team. We appreciate all comments, questions, feature requests, critiques even! :)
