What is Pro Edition for Mosquitto MQTT broker

Pro Edition for Eclipse Mosquitto product offering

Pro Edition for Mosquitto MQTT broker is a fully supported version of the leading Mosquitto open-source project offering high availability and high performance to its customers worldwide.

It is a message broker that stands in the center of IoT architecture and enables communication between clients, including sensors, smartphones, web apps, and other devices. Thanks to its high efficiency, the movement of data, e.g., texts, images, .json files, and more, requires only minimum bandwidth and computing resources, resulting in low CPU and RAM.

Cedalo offers both managed (cloud) and self-hosted (on-premises) MQTT servers available for Windows, Mac, and Linux.

Core features of our MQTT message broker

High Availability

Ensure that your solution is 24h available, so that you can fully rely on it. Set up at least three MQTT broker nodes and form a cluster. If the leading node fails, another one will seamlessly take over the role of the main server and continue smooth operation. Enjoy peace of mind when adopting an MQTT message broker for any critical application.

Optimized Performance

Benefit from the low usage of CPU and RAM resources thanks to the superior architecture of Mosquitto. Run 100,000 and more connections on a single MQTT server node. Use the Performance Dashboard to monitor the load on your brokers, like the number of connected clients, active subscriptions, and processed data volumes.


Leverage our MQTT server’s native Dynamic Security Plugin to perform fast authentication and manage access rights of users based on groups and roles. Open or close ports based on your business needs (per default, they are closed). Change security settings on the fly and without re-boot.

Rest API

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

Graphical Managament Center

Administer and monitor your MQTT broker with a convenient graphical interface. The Management Center is separated from the actual broker by a proxy layer. The proxy layer and GUI don’t run on the same CPU and memory as the broker. As a result, you get the convenience of a modern user interface without losing the efficiency of your lightweight MQTT broker.

On-premises and hosted by Cedalo

Feel free to choose the professional license you need: on-premises or hosted by us. If you want to completely take over the software’s running and infrastructure, select the on-premises version. If you do not want to do it but rather subscribe to a service and do not worry about infrastructure or operations, the Cedalo hosted version is your best choice.

How Pro Edition for Mosquitto MQTT server works

The Pro Edition for Mosquitto MQTT message broker serves as the core communication element in an MQTT environment. It is responsible for routing messages from publishing to the correct subscribing clients, as well as maintaining detailed access rights for clients and users.

How MQTT server works
  1. Clients and the MQTT broker establish a connection.
  2. Publishing clients publish messages on topics. The MQTT broker supervises writing permissions.
  3. Subscribers may subscribe to a certain topic and, by doing so, receive all messages sent to it by publishers.

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