Liftbridge provides lightweight, fault-tolerant message streams by implementing a durable stream augmentation for the NATS messaging system. It extends NATS with a Kafka-like publish-subscribe log API that is highly available and horizontally scalable. Use Liftbridge as a simpler and lighter alternative to systems like Kafka and Pulsar or use it to add streaming semantics to an existing NATS deployment.
See the introduction post on Liftbridge and this post for more context and some of the inspiration behind it.
