Compare the Top Event Brokers as of July 2025

What are Event Brokers?

Event brokers are middleware platforms that manage the flow of events between different systems or applications in an event-driven architecture (EDA). These brokers facilitate the decoupling of event producers and consumers by handling the publishing, routing, and consumption of events in real time. They allow systems to asynchronously process and respond to events such as data changes, user actions, or external triggers without direct interaction between the components. Event brokers are often used in microservices architectures, IoT ecosystems, and real-time data processing systems to enable efficient and scalable communication. Compare and read user reviews of the best Event Brokers currently available using the table below. This list is updated regularly.
