Liftbridge is a lightweight, fault-tolerant message streaming system written in Go that implements a durable, replicated message log on top of NATS. It serves as a simpler 'Kafka-lite' alternative to Kafka or Pulsar, shipped as a single binary with no JVM or ZooKeeper dependency.

Use cases

• add durable streaming semantics to an existing NATS deployment
• replace Kafka with a lighter single-binary message log for Go services
• build event-driven microservices with replicated message streams
• run a lightweight pub/sub log without JVM or ZooKeeper overhead
• ingest high-throughput events with low latency and durable storage

When to choose

• your stack is Go-centric and you want a canonical Go client and server
• you need Kafka-style durable, replicated streams but not Kafka's operational weight
• you already run NATS and want to add stream replay and durability
• you want a single-binary deployment with no JVM or ZooKeeper

When to avoid

• you need Kafka's full ecosystem, exactly-once semantics, or huge partition counts
• you require very large message sizes or tiered storage
• you need a mature, battle-tested system at massive scale
• you want managed cloud offerings with broad vendor support
