NATS - The Edge & Cloud Native Messaging System

NATS provides an always-on messaging system, encompassing traditional pubsub with interest-based propagation, persistence with streaming replays, key/value storage and object storage. NATS provides a flexible set of powerful authentication and authorisation access controls.

NATS is a CNCF incubating project, donated by and primarily developed by Synadia Communications.
