Surgewave

The complete event streaming platform for .NET 10.

Surgewave is a complete event streaming platform built end-to-end on .NET 10 — native low-latency transport, signed plugin marketplace, built-in AI pipeline nodes, embedded broker for tests and edge. Full Kafka 4.0 wire compatibility ships in the box, so any existing Kafka client (Confluent.Kafka, librdkafka, kafka-go, …) connects on day one. Adopt Surgewave as your streaming platform; keep your existing Kafka producers and consumers working unchanged.

What Surgewave Does

Surgewave connects your services, devices, and data in real time. It distributes events reliably, processes streams on the fly, and stores them durably.

• Decouple microservices with pub/sub and request/reply
• Ingest IoT data from edge devices to the cloud
• Replicate database changes with built-in Change Data Capture (CDC)
• Transform, filter, join, and aggregate streams in real time. Use a fluent .NET API or SQL.
• Store events with configurable retention. Choose the storage engine for your use case: file-based, in-memory, shared-memory, database, or bring your own.
• Implement CQRS and event sourcing with ordered, replayable event logs
• Built-in dashboards and materialized views. Integrate into your existing monitoring via OpenTelemetry (OTEL).

Why Surgewave?

Easy to adopt

• Wire-compatible with Kafka 4.0. Run alongside Kafka or replace it entirely.
• Your existing clients, tools, and monitoring keep working.
• Just swap the broker and keep your Kafka clients. Or use Surgewave's .NET client, which switches protocols at runtime.
• Migrate service by service, in either direction.

Easy to operate

• Pure .NET, no JVM, no ZooKeeper. One technology stack, one team.
• Run embedded in your app, as a standalone broker, or scaled out across a cluster.
• Your .NET team can build, deploy, and troubleshoot everything with the skills they already have.

Built for performance

• Designed from scratch on .NET 10 with zero-copy and io_uring.
• Lower latency, higher throughput, less hardware.

Built for extensibility

• Add storage engines, protocol adapters, or connectors as plugins.
• Package as .swpkg files, install at runtime, no fork required.

Quick Start

Start the broker:

docker run -p 9092:9092 -p 5050:5050 ghcr.io/kuestenlogik/surgewave

Open the Control UI at localhost:5050. See the for a walkthrough.

No Docker? See Building from Source below.

Connect with any Kafka client:

var config = new ProducerConfig { BootstrapServers = "localhost:9092" };
