Project history and usage

NATS Streaming Server, also called STAN, was the reliable streaming layer that predated JetStream in the NATS ecosystem. It added persistence, durable subscriptions, acknowledgements, and replay-style messaging on top of core NATS for users who wanted lightweight streaming without running a larger broker stack.

Project history

The GitHub repository was created on 2016-03-24 and the project reached its final published GitHub release, v0.25.6, on 2023-11-17. The repository README says NATS Streaming Server is deprecated, with critical bug and security fixes applied until June 2023, and directs persistence users to JetStream. GitHub marked the repository archived on 2025-12-31.

The replacement path is explicit in the NATS documentation: JetStream is built into nats-server and the docs state that JetStream completely replaces the legacy STAN streaming layer.

Adoption history

NATS Streaming Server mattered during the period when NATS users needed persistent streams before JetStream became the standard NATS persistence engine. Its adoption footprint is now mostly legacy maintenance and migrations: Homebrew listed the formula as deprecated on 2026-07-01 and reported 193 installs over the preceding 365 days.

How it is used

Package users installed the standalone `nats-streaming-server` binary to run a STAN server beside NATS clients. Practical use involved provisioning channels, durable subscribers, and client libraries for applications that needed message replay or at-least-once delivery. New deployments are expected to use JetStream in `nats-server` instead.

Why package nerds care

This is a package-history marker for a superseded infrastructure component: keeping it packaged helps old deployments and migration tests, while the formula deprecation and upstream archive tell package maintainers not to treat it as a living NATS server family member.
