Core features of the Pro Edition for Mosquitto MQTT message broker

High Availability icon

High Availability

Enjoy the fail-free operation of your IoT systems and peace of mind when adopting an MQTT message broker for any critical application. With the MQTT High Availability functionality, your devices can uninterruptedly communicate with the broker. Thanks to clustering, you get a fully synchronized setup of three brokers, where each broker node will seamlessly take over the role of the primary server if the leader node fails. Discover more about the MQTT High Availability.

Optimized Performance icon

High Performance

Benefit from Mosquitto’s superior architecture that utilizes only 15-20% of CPU and RAM power of comparable products. Leverage Pro Edition for Mosquitto’s capability to run on very low-spec embedded devices, e.g., single core 600MHz ARM and 128MB RAM. Implement sophisticated IoT systems that can maintain up to 1 million connections on a single MQTT server node. Manage persistent sessions more accurately with the high-performance local persistence database.

Persistent Queueing

Leverage Persistent Queueing to increase the MQTT broker’s storage capacity by directly queuing messages to disk. Retain multiple terabytes of queued messages per client and MQTT bridge to ensure message delivery even in environments with unstable connectivity. By offloading message storage from RAM space, you can optimize resource utilization and enable the broker to scale effectively to accommodate future growth and increasing message volumes.

Security icon


Leverage our MQTT server’s native Dynamic Security Plugin to perform fast authentication and manage user access rights based on groups and roles. Open or close ports depending on your business needs and change security settings on the fly without rebooting. Connect to Mosquitto Management Center to manage Certificate Authority (CA). Utilize the Audit Trail feature to capture every essential action, ensuring data integrity and creating an append-only log. Manage your MQTT broker from external apps using application tokens with role-based access, expiration dates, and more.

Mosquitto Management Center (MMC)

Administer and monitor your MQTT broker with a convenient graphical interface. A proxy layer separates the Mosquitto Management Center MQTT client from the broker. The proxy layer and GUI don’t run on the same CPU and memory as the broker. Therefore, you get the convenience of a modern user interface without losing the efficiency of your lightweight MQTT broker. In addition, benefit from greater visibility by accessing detailed information on all connected MQTT clients, visualizing your topic tree, creating and managing MQTT broker connections, HA clusters, and more.


Use the Management Center’s REST API to automate the administration of the MQTT broker and integrate it further. Our HTTP endpoints provide data on the status and allow managing clients and users. In other words, automate actions and operations, including those carried out through the Management Center or interactions with other applications, e.g., “querying a topic tree.” Learn more about MQTT API and REST API.


Enable multiple broker connections through a Mosquitto Bridge, or use an HTTP Bridge to forward information from a broker to a web service with an HTTP endpoint. Leverage a diverse range of bridges, including Kafka, MongoDB, Google Pub/Sub, Google AlloyDB, MySQL, PostgreSQL, TimescaleDB, or MongoDB Atlas and discover ways to harness MQTT data to generate insights for process optimization and informed decision-making. Enhance monitoring capabilities by utilizing Prometheus or InfluxDB Metrics exporter to access historical data for various Pro Edition for Mosquitto metrics. Use this data to ensure your service’s optimal performance and reliability, enable capacity planning, and facilitate rapid anomaly detection and response.

How the Pro Edition for Mosquitto MQTT server works

The Pro Edition for Mosquitto MQTT message broker is the core communication element in an MQTT environment. It routes messages between publishing and subscribing MQTT clients, ensuring the latter performs as little data processing as possible.

How MQTT server works
  1. Clients and the MQTT broker establish a connection.
  2. The MQTT broker supervises writing permissions and obtains messages published by clients.
  3. The MQTT broker routes the published messages to the clients subscribed to respective topics.

Recommended: Only work with authenticated connections. Enable TLS encryption to ensure secure communication.

Open-source or Pro Edition for Mosquitto MQTT Broker?

The open-source version of Mosquitto MQTT broker is a reliable solution for building a personal IoT project. It can also be a workable solution for commercial systems. However, in this case, you have to accept the risks this would entail in terms of performance, security, and troubleshooting. That is why, for commercial purposes, we recommend you opt for Pro Edition for Eclipse Mosquitto.

In addition to providing a fully managed cloud version, Pro Edition for Mosquitto offers premium features unavailable in its open-source counterpart. These include a local persistence database, persistent queueing, advanced broker and client administration and monitoring, user management (role-based access control), REST APIs, HA, integrations (Prometheus, and InfluxDB Metrics exporter, or HTTP, Kafka, MongoDB, TimescaleDB, and Google Pub/Sub bridge), and many others. The on-premises Pro version can seamlessly integrate with OpenShift and Kubernetes to manage and scale Pro Edition for Mosquitto alongside other applications and services in containerized environments, and is also available as Red Hat Linux packages (RPM files).
