What is the Pro Mosquitto MQTT broker?

Pro Edition is a commercial-grade Mosquitto MQTT broker with a robust feature set and dedicated support channels.

Compared to the open-source version, Pro Mosquitto provides a professional MQTT broker and client administration, available through the Mosquitto Management Center web interface. It also offers MQTT High Availability, a robust set of MQTT and REST APIs, enterprise-level integrations such as Kafka and MongoDB bridges, the Prometheus exporter, etc., improved reliability, enhanced security, and other features, making it an ideal solution for your IoT project.

Mosquitto implements the full Sparkplug Awareness broker functionality for industrial device and software system interoperability, ensuring consistent and reliable data exchange.

Pro Mosquitto can be deployed as a managed (cloud) or self-hosted (on-premises) instance run on Docker (Linux, Windows, macOS, Raspberry Pi), RPM (RedHat, CentOS, Rocky Linux) and Kubernetes (Linux, Windows, macOS) to match your budget, IoT infrastructure and business needs.

Core features of the Pro 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 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.

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 Kafka Bridge to connect your MQTT environment to Kafka and discover ways to analyze and utilize MQTT data for process optimization and informed decision-making. Establish a MongoDB Bridge to process your MQTT data in MongoDB, perform further analysis, and generate insights. Enable Prometheus exporter to query metrics from Pro Mosquitto and access historical data for better monitoring, capacity planning, and rapid anomaly detection.

How the Pro 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.

Clients about us

Hans Michael Krause

“Due to its stability, resource efficiency, and performance, we chose to make the Pro Edition for Mosquitto the standard MQTT broker on the new automation platform ctrlX AUTOMATION of Bosch Rexroth.

For our broad customer base in factory automation, smart manufacturing, and infrastructure technology, it is essential that Cedalo, as the company behind this iconic software, provides professional support within our open ecosystem ctrlX World. Cedalo also did an excellent job seamlessly integrating Mosquitto into the ctrlX AUTOMATION environment.

We look forward to further adopting Pro Edition features, like the MQTT High Availability, onto the ctrlX CORE edge controller soon.”

Open-source or Pro 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.

Besides providing a fully managed cloud version, Pro Mosquitto offers premium features not available in its open-source counterpart, including a local persistence database, advanced broker and client administration and monitoring, user management (role-based access control), REST APIs, HA, integrations (Prometheus exporter, or HTTP, Kafka, and MongoDB bridge), and many others. The on-premises Pro version can seamlessly integrate with the Kubernetes container orchestration and is also available as Red Hat Linux packages (RPM files).
