Memphis Message Broker

This open-source next-generation message broker is designed for modern data streaming and event-driven architectures. Founded by Yaniv Ben Hemo in 2022, the project has raised seed funding and has over 8,300 stars as of 2026. It positions itself as a modern alternative to Kafka, RabbitMQ, and NATS, focusing on developer experience, simplicity, and built-in observability. Key features include: station-based messaging (organizing messages into stations with built-in schema management, retention policies, and dead-letter handling), SDK support (Node.js, Python, Go, Rust, TypeScript, .NET with simple produce and consume APIs), schema management (built-in registry supporting JSON Schema, Protobuf, and Avro with automatic validation and versioning), message processing (streaming and asynchronous patterns with consumer groups), dead-letter station (automatic routing of failed messages for inspection and reprocessing), observability (built-in Grafana dashboards, message tracing, and analytics without external tools), self-healing (automatic reconnection and recovery), tiered storage (offloading old messages to S3-compatible storage), REST and WebSocket gateway (non-SDK message production via HTTP and WebSocket), Kubernetes-native (Helm chart deployment), Docker Compose (single-command deployment), and multi-region (cross-region message replication).
