NATS
NATS is a lightweight, high-performance messaging system for microservices, IoT and edge workloads. With JetStream switched on it also stores messages: durable streams, replay, consumers with acknowledgements, key-value buckets and object stores, all from one small binary.
Disclosure: deploy links carry the author's Railway referral code — the author receives a usage kickback when you deploy. The template itself is free to deploy; Railway usage charges apply.
