What we like
Deployed as a single (C++) binary - no JVM. No Zookeeper. Use any Kafka library. Comes with a web console out of the box and can be managed via a CLI (which includes tuning features). Built-in schema registry. Prometheus endpoints. Tiered storage to offload to object storage. Run it yourself, in the cloud, or bring your own cloud.
What we don't like
Schema registry functionality is limited to registration - does not do any deep schema validation and docs are limited about how to use it with Kafka SDKs.
Console is the place developers go to find the best tools. Each week, our weekly newsletter picks out the most interesting tools and new releases. We keep track of everything - dev tools, devops, cloud, and APIs - so you don't have to.
