Message Queue Simulator: Visualize Kafka and RabbitMQ Queues

An interactive browser-based simulator that visualizes how message queues work in both Kafka and RabbitMQ systems. Users can explore producers, brokers, topics, partitions, consumer groups, lag, rebalancing, backpressure, and dead letter queues without running real infrastructure. The simulator covers key concepts like at-least-once delivery, offset management, exchange bindings, acknowledgment modes, and poison message handling — helping developers understand queue mechanics before operating brokers in production.
