• Demo: N/A (test locally with docker run --rm -it -p 5672:5672 -p 15672:15672 -v /tmp/lavinmq:/var/lib/lavinmq cloudamqp/lavinmq — management UI at http://localhost:15672 with guest/guest)

• Summary:
  LavinMQ is a high-performance message queue and streaming server implementing the AMQP 0-9-1 (RabbitMQ compatible) and MQTT 3.1.0/3.1.1 protocols. Written in Crystal, it delivers lightning-fast throughput (up to 800k msgs/s), extremely low memory usage, and the ability to handle huge numbers of connections/long queues. Key features include a clean web-based management UI + HTTP API, clustering/high-availability with automatic leader election, stream queues, delayed exchanges, priorities, dead-lettering, TTL, federation, shovels, and more.

---

• Notes:

It is dramatically more resource-efficient and faster than the classic Erlang-based RabbitMQ while staying 100% wire-compatible with all RabbitMQ client libraries. Official Docker support and simple config make it a perfect fit for Cloudron packaging. The management interface is modern and intuitive.

Minor concerns: full HA clustering needs etcd (standalone mode works great out of the box); community is growing but still smaller than RabbitMQ’s. Actively maintained by the CloudAMQP/84codes team.

Likely main problems that packagers might encounter:Handling multiple ports (AMQP 5672 + Management UI 15672; MQTT optional) — Cloudron proxies the HTTP UI easily but raw TCP ports need extra manifest config
Persistent data volume — mapping /var/lib/lavinmq to /app/data with correct permissions and updating data_dir in config
Dynamic config management — generating and mounting /etc/lavinmq/lavinmq.ini for paths, ports, users and features
Authentication — built-in user system only (no Cloudron SSO); must replace insecure default guest/guest on first run
Clustering/HA — full high-availability requires a separate etcd service (single-node is straightforward)
TLS setup — integrating Cloudron certs for secure AMQP/MQTT connections

Not familiar with Crystal, but one of the strengths of RabbitMQ is that is built with Erlang, a battle-tested, high-performance, fault-tolerant platform.
