Instead of Lightstreamer
Lightstreamer alternatives
Lightstreamer delivers live data to web and mobile apps while adapting its flow to network conditions. It supports publish/subscribe, request/response, and client-to-server messaging, with fine-grained subscriptions and WebSocket or HTTP transport selection. Connectors for Kafka, MQTT, and JMS, broad client SDK support, and on-premises or cloud deployment suit business-critical systems that need to keep clients synchronized through network interruptions and congestion.

A different broker may fit better if your priority is IoT protocols, open-source deployment, or a particular messaging architecture. Lightstreamer’s free Demo License is limited to 20 concurrent connections; production plans require a tailored proposal, and its free non-production license requires a Production License and periodic server restarts. When switching, weigh protocol support, delivery and recovery behavior, scaling model, security controls, deployment, and how each product connects applications or devices. The alternatives below vary from MQTT-focused IoT servers to general-purpose message brokers and pub/sub systems.
