NATS
The Real-Time Communication Fabric for Distributed Applications

NATS is a high-performance, open-source messaging system designed for building modern distributed systems across cloud, on-premise, edge, and IoT environments. It supports pub/sub, request/reply, and streaming with persistence via JetStream, all through a single lightweight binary with sub-millisecond latency. Official and community clients are available for over 45 programming languages and platforms.
NATS provides a single binary that unifies pub/sub, request/reply, streaming, key-value, and object storage with minimal resource usage, supporting topology expansion via leaf nodes and superclusters without downtime.
