Karafka is a Ruby and Rails efficient Kafka processing framework.
Karafka allows you to capture everything that happens in your systems in large scale, without having to focus on things that are not your business domain.
Karafka is a Ruby and Rails multi-threaded efficient Kafka processing framework that:
- Has a built-in Web UI providing a convenient way to monitor and manage Karafka-based applications.
- Supports parallel processing in multiple threads (also for a single topic partition work) and processes.
- Automatically integrates with Ruby on Rails
- Has ActiveJob backend support (including ordered jobs)
- Has a seamless Dead Letter Queue functionality built-in
- Supports in-development code reloading
- Is powered by librdkafka (the Apache Kafka C/C++ client library)
- Has an out-of the box AppSignal and StatsD/DataDog monitoring with dashboard templates.
If you're entirely new to the subject, you can start with our "Kafka on Rails" articles series, which will get you up and running with the terminology and basic ideas behind using Kafka:
- Kafka on Rails: Using Kafka with Ruby on Rails – Part 1 – Kafka basics and its advantages
- Kafka on Rails: Using Kafka with Ruby on Rails – Part 2 – Getting started with Rails and Kafka
If you want to get started with Kafka and Karafka as fast as possible, then the best idea is to visit our Getting started guides and the example apps repository.
We also maintain many integration specs illustrating various use-cases and features of the framework.
I also sell Karafka Pro subscriptions. It includes a commercial-friendly license, priority support, architecture consultations, enhanced Web UI, and high throughput data processing-related features (virtual partitions, long-running jobs, and more).
10% of the income will be distributed back to other OSS projects that Karafka uses under the hood.
Help me provide high-quality open-source software. Please see the Karafka homepage for more details.
Karafka has Wiki pages for almost everything and a pretty decent FAQ. It covers the installation, setup, and deployment, along with other useful details on how to run Karafka.

Karafka has priority support for technical and architectural questions that is part of the Karafka Pro subscription.
