Dekaf / The pure C# Apache Kafka client
Kafka, fluent
in C#.
All the Kafka.
Right at home in .NET.
Produce, consume, and work with Kafka through a fully managed client. Built in C#, from the fluent API to the wire protocol.
Start buildingExplore the sourceNo native libraries to ship.No interop layer to cross.Just .NET 10+.
Small API.
Big conversations.
Start with a broker address and a topic. Fluent builders and async streams make the rest feel familiar.

Read async streams, share work across groups, and take control of offsets.
Make it your stack
Plug in serializers, compression, and the .NET services you already use.
Less work for the runtime.
More room for your messages.
Spans, pooled buffers, and ValueTask keep allocations off the hot path. Explore the benchmarks and the decisions behind the performance.
