LavinMQ is a high-speed, open-source message broker designed for efficient message queuing and streaming. It enables reliable, asynchronous communication between distributed systems, microservices, IoT devices, and legacy infrastructure. Built for performance and simplicity, LavinMQ supports the AMQP 0-9-1 protocol, offers broad client language compatibility, and is suitable for handling millions of messages per second. Its architecture supports both single-node and clustered deployments with replication, ensuring high availability and data safety. The system is delivered as a single binary for easy installation and management, and includes a user-friendly web interface for monitoring and configuration.
