Message queue software moves messages between systems, so compare how each option handles delivery, persistence, and scale. Delivery guarantees, protocols, and deployment choices help distinguish approaches; message retention and maximum message size are useful when considering what the queue must hold and for how long. Throughput limits, free-plan availability, and paid-from details offer further points to weigh. IBM MQ and Aiven for Apache Kafka appear first, followed by Apache Pulsar and Confluent Cloud. HiveMQ MQTT Broker, RabbitMQ, Redpanda, and Amazon SQS are also among the first entries. Match the listed limits and protocols to the messaging requirements you need to support.
