In their own words
Lightstreamer
Lightstreamer is an event broker for delivering real-time data to web and mobile applications, including across proxies, firewalls, disconnections, and network congestion. Intelligent Streaming adjusts data flow to network conditions and can resample or combine updates to keep users synchronized. Messaging options include publish/subscribe, request/response, client-to-server messaging, and fine-grained item and field subscriptions. StreamSense chooses WebSockets or HTTP connections for each client, including through restrictive firewalls and legacy proxies.
Ready-made connectors cover Kafka, MQTT, and JMS, with named examples including Confluent Cloud, Amazon MSK, Redpanda, AWS IoT Core, IBM MQ, and ActiveMQ. Custom adapters can be built with Java, Python, Node.js, .NET, and TCP sockets. Lightstreamer supports TLS, certificates, mutual authentication, and custom authentication and authorization. It can be deployed on-premises or in the cloud, with Helm, Docker, and Kubernetes support. Monitoring options include a web dashboard, configurable logs, JMX, Prometheus, and Grafana integrations. The free Non-Production Limited License requires a Production License and a server restart after at most 210 minutes of uptime.
