[NATS](https://nats.io) is a simple, secure and performant communications system for digital systems, services and devices. NATS is part of the Cloud Native Computing Foundation ([CNCF](https://cncf.io)). NATS has over [40 client language implementations](https://nats.io/download/), and its server can run on-premise, in the cloud, at the edge, and even on a Raspberry Pi. NATS can secure and simplify design and operation of modern distributed systems.
