Discover NATS for scalable, secure, and rapid messaging in distributed systems. Supports pub/sub, streaming, and multi-language clients.

Overview: NATS is a high-performance messaging system designed for modern distributed systems. As a message-oriented middleware, it facilitates effortless communication between applications and services across different environments. Whether on-premise or in the cloud, NATS provides scalable and decentralized messaging with support for various patterns such as publish/subscribe, request/reply, and streaming.
NATS is a connective technology powering modern distributed systems, unifying Cloud, On-Premise, Edge, and IoT.

Key Features

  • Lightweight & Fast: Designed with performance in mind, NATS offers an incredibly lightweight server that facilitates high-speed message passing.
  • Scalability: NATS servers can be clustered to form a high-throughput, fault-tolerant messaging network that scales up seamlessly with your application needs.
  • Multiple Quality of Service Levels: With Core NATS and JetStream, developers can choose between at-most-once and at-least-once delivery guarantees to suit different use cases.
  • Secure: Supports multiple authentication mechanisms including traditional username/password, tokens, and advanced options like JWTs and Nkeys.
  • Language Agnostic: Offers numerous client libraries that allow developers to integrate NATS into applications written in different programming languages.
  • Distributed Systems Friendly: NATS simplifies service discovery and load balancing which are essential for microservices architectures.
  • Multi-tenancy Support: Enables secure multi-tenant operations through authorization and subject partitioning.
  • Persistent Storage: With JetStream, developers can leverage on-disk storage for message retention and durable subscriptions.
  • Fault Tolerance: Built-in fault tolerance ensures message delivery even in the event of network interruptions or server failures.
  • Simplified Connectivity: Clients need only a URL and optional authentication credentials to connect to the messaging system.
