Liftbridge – Kafka-style streams in Go, built on NATS

We (Basekick Labs) we are the new maintainers of Liftbridge. It went dormant in 2022, and we're reviving it.

Liftbridge adds Kafka-style durability to NATS: commit log, partitions, ISR replication. Single Go binary, no JVM or ZooKeeper.

Architecture: Raft for metadata consensus, ISR (like Kafka) for data replication. Memory-mapped segment files with offset/timestamp indexes.

We're using it for Industrial IoT (streaming layer for Arc, our time-series database), but it works standalone.

Roadmap: Go 1.25+, dependency updates, security audit, CI/CD fixes (Done) and we fixed a few panic errors / race conditions bugs. First release mid January 2026.

Happy to answer questions.
