It belongs to the practical RabbitMQ-adjacent world of queue servers, but its package-manager appeal is that it packages a comparatively small, fast broker with a CLI and benchmarking tool. ### Project history The public GitHub repository was created on May 3, 2017. Early public release artifacts include v0.3.2 on August 23, 2018, followed by a long pre-1.0 series before v1.0.0 was published on March 31, 2023. The project reached v2.9.1 on July 1, 2026. ### Adoption history LavinMQ's adoption path is tied to CloudAMQP's managed messaging background and to packaging for ordinary service deployment. The official README documents Debian/Ubuntu, Fedora, Arch Linux AUR, Homebrew, Docker, Docker Compose, Windows via WSL, and source builds, which places it in the same operational lane as other infrastructure daemons distributed through both OS packages and containers. ### How it is used The server runs as `lavinmq` with a data directory, while `lavinmqctl` talks to its control socket and `lavinmqperf` supports benchmarking. Official docs and README material emphasize AMQP client compatibility, MQTT support, Docker deployment, and minimal setup. ### Why package nerds care For package nerds, LavinMQ is notable because it turns a message broker into a small Crystal-built formula with service-style configuration rather than a sprawling JVM-era broker install. Its Homebrew formula is especially useful for local AMQP/MQTT development and for testing queue behavior without pulling in a heavier stack. ### Timeline - 2017: Public GitHub repository created - 2018: v0.3.2 release published - 2023: v1.0.0 release published - 2026: v2.9.1 release published ### Related projects - RabbitMQ is the obvious protocol-adjacent reference point for AMQP 0-9-1 workflows. CloudAMQP also maintains a LavinMQ Kubernetes operator and LavinMQ benchmark repository, both linked from the official README. ### Sources - - - - - - ## Security Notes formula declares a Homebrew service. - **Geiger risk:** orange / medium - formula declares a Homebrew service ## Configuration and credential file locations These source-backed paths show where this package keeps local settings or durable credentials.
