What it is

Building block

What it does

A streaming data platform that speaks the Kafka API, written in C++ as a single binary with no JVM or ZooKeeper.

Adopt it when

You want Kafka-compatible streaming with simpler operations and lower latency, and existing Kafka clients must keep working.

Watch out

The core is under the Business Source Licence, not an open-source licence, and several enterprise features need a paid licence.

Ready for

Production-ready

Runs as

Self-hosted server and cloud service

Built with

C++, Seastar and Go

How established

Established: started 6 years ago, latest release v26.2.2.
