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 ### Why package nerds care This is a package-history marker for a superseded infrastructure component: keeping it packaged helps old deployments and migration tests, while the formula deprecation and upstream archive tell package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. ### Timeline - 2016-03-24: GitHub repository created. - 2023-06: Upstream deprecation window for critical bug and security fixes ended. - 2023-11-17: v0.25.6 released. - 2025-12-31: GitHub repository archived. ### Related projects - NATS, nats-server, JetStream, and the legacy STAN client libraries are the important adjacent projects. ### Sources - - - - - - ## Security Notes broad file, network, media, or database tool signal. formula declares a Homebrew service. - **Geiger risk:** orange / medium - broad file, network, media, or database tool signal - formula declares a Homebrew service - infrastructure mutation or orchestration signal ## Source Database Details - **Source Database:** Homebrew formula API - **Tap:** homebrew/core - **Full Name:** nats-streaming-server - **Version Scheme:** 0 - **Revision:** 0 - **Head Version:** HEAD - **Bottle Stable Root URL:** - **Deprecated:** yes - **Disabled:** no - **Keg Only:** no - **URL Keys:** head, stable ## Related links - [Secret-risk packages](https://www.automicvault.com/pkg/secret-risk-packages/) - Has protected-tool coverage, approval-gate, or non-low Geiger security signals. - [Terminal utility packages](https://www.automicvault.com/pkg/terminal-utilities/) - Matched terminal and command-line workflow metadata. - [Networking and protocol packages](https://www.automicvault.com/pkg/networking-protocol-tools/) - Matched network, protocol, or remote-service metadata. - [Homebrew utility packages](https://www.automicvault.com/pkg/brew-utility-packages/) - Matched Homebrew package provider. - [go](https://www.automicvault.com/pkg/brew/go/) - Build dependency declared by Homebrew. - [nats-server](https://www.automicvault.com/pkg/brew/nats-server/) - Shares the same upstream homepage. - [rabbitmq](https://www.automicvault.com/pkg/brew/rabbitmq/) - Shares av.db curated category or tags: cli, messaging, networking, server, streaming. - [activemq](https://www.automicvault.com/pkg/brew/activemq/) - Shares av.db curated category or tags: cli, messaging, networking, server. - [ejabberd](https://www.automicvault.com/pkg/brew/ejabberd/) - Shares av.db curated category or tags: cli, messaging, networking, server. - [czmq](https://www.automicvault.com/pkg/brew/czmq/) - Shares av.db curated category or tags: cli, messaging, networking. - [emqx](https://www.automicvault.com/pkg/brew/emqx/) - Shares av.db curated category or tags: cli, messaging, networking. - [libpaho-mqtt](https://www.automicvault.com/pkg/brew/libpaho-mqtt/) - Shares av.db curated category or tags: cli, messaging, networking. - [memcacheq](https://www.automicvault.com/pkg/brew/memcacheq/) - Shares av.db curated category or tags: cli, messaging, networking, server. ## Combined YAML source View the package source record on GitHub.
