HiveMQ Cloud Frequently Asked Questions

Technical FAQs

Each concurrent MQTT client session is counted as a single connection. Therefore, if a client device opens more than one session at a time, each one will be counted as a unique connection. These numbers are reset at the end of the monthly billing period.


  • If 37 client devices connect every hour on the hour and disconnect after 10 minutes, the total connection count for the day will remain 37.
  • If 10 client devices connect with a persistent session (cleanSession flag is set to false) and disconnect again, and another 27 devices connect on the hour for 10 minutes before disconnecting the total for the day will also be 37.

For billing purposes, only PUBLISHED messages are counted. To best balance billing between customers we ‘normalize’ messages to a value of 5KB. For example, if you send an 8KB message, it will be counted as two normalized messages. The message’s topic, headers, and payload (and if using MQTT5, user properties) are all combined in this sizing calculation.

We offer unlimited connections. However, usage is subject to a fair usage policy and service agreements. To ensure we’re providing the best service and uptime, we temporarily cap connections at 25,000. If you require more connections, simply reach out via or the Help page on Cloud Console. The number of active connections is visible in the HiveMQ Control Center.

HiveMQ Cloud is fully compliant with the MQTT Standard, including interoperable support for
MQTT 3.1, MQTT 3.1.1, and MQTT 5. For more details on MQTT protocol, please visit our MQTT FAQs

The HiveMQ Cloud terms and conditions can be found here. Service Level Agreements (SLAs) are applicable only on production tiers so there is no uptime SLA for Serverless (Free & PAYG).

  • Starter: 99.95%
  • Professional and Enterprise: 99.99%
  • Serverless and Starter: Only AWS is currently available
  • Professional and Enterprise: Yes

We are developing a usage-based cost calculator that will be available on our website in the coming weeks. The average cost for running a HiveMQ Cloud Starter cluster for 30 days is $250, with each million incoming normalized messages costing an additional $0.80.

Billing and Invoice

You can find your invoices under the menu "Billing & Payment" in the Cloud console.

HiveMQ Cloud Starter Plan is currently Credit Card only, but we plan to add additional options in the future. We support multiple payment options for the HiveMQ Cloud Enterprise plan, including annual invoicing. Please reach out to our sales team to learn more about these options.

Students can use the Free tier on the HiveMQ Cloud Serverless Plan without any additional costs. We do not offer any student discounts on other plans. Please contact us if you have any special requirements.

Migrating between Starter or above plans is easy and will keep your configurations. There might be some configuration we can’t migrate if you are changing a plan, but you will be informed about this exception during the upgrade process. Currently, HiveMQ does not support migration from Serverless plans.

You can cancel your paid plan easily by selecting the "delete cluster" option in the cluster details overview.

We will inform you about the failed payment and try to charge you again within a few days. We will also provide you the option to change your credit card. If we are not able to collect payment, the cluster will be stopped.

This depends on the method you used during sign-up. If you have chosen the username-password sign-up method, we can change the associated email address with your account. If you have used any social sign-up method we cannot change the associated email address, as this is bound to your social login.

  • Starter: We bill by the hour that each customer cluster is running, which requires monthly invoicing in arrears to cover the cost for that period.
  • Enterprise: Pricing is based on your needs and defaults to annual terms.

Yes, it is that easy. If you have used Serverless in the past, you will find a very similar onboarding experience.


You can raise a support request via the support widget in the Cloud Portal. It is accessible via the “Help” menu on the Cloud console.

You can raise a support ticket 24 hours a day, while our support business hours are 9am to 5pm CET and EST. Response times depend on the HiveMQ Cloud plan and are found under HiveMQ Cloud terms and conditions.

Our sales team is eager to understand your requirements and talk to you about our tailored HiveMQ Cloud Enterprise offering or help you identify which of our HiveMQ Cloud plans will fit your needs best.

Linear and transparent scaling of client subscriptions in order to load balance message processing across multiple workers. The load balancing is facilitated by a smart algorithm that takes the load of subscribing clients into account. Linear Scaling Shared Subscription Sharding Gray Minus
epoll is a Linux kernel system that provides better performance in more demanding applications, where the number of watched file descriptors is large. Linux Epoll Support Gray Minus Gray Minus
The $expired, $dropped and $dead topics enable you to capture "lost" messages to avoid loss of data and improve error analytics and handling capabilities. MQTT Add-ons Gray Minus Gray Minus
Helps the broker identify connecting clients with their unique IP addresses. Without the Proxy Protocol, the broker cluster will only see the IP address of the intervening load balancer. It’s helpful if clients with unidentifiable ClientIDs connect to a cluster behind a load balancer as the proxy protocol carries over connection information to the broker in this case. Without the proxy protocol the broker would only see the IP of the load balancer. So it helps to identify clients via their source IP address. Proxy Protocol Gray Minus Gray Minus Gray Minus
The HiveMQ Marketplace is a catalog of pre-built extensions built by the HiveMQ team and the HiveMQ community. HiveMQ Extension Marketplace
They provide a rich set of extension interface that can be used to customize various aspects of a MQTT lifecycle including Client settings, Subscription Management, Publish and Retained Message behavior. Additionally, external systems can be integrated and Admin and Cluster services can be managed in a customized fashion. Community Extension SDK

A broker cluster can be upgraded in a zero downtime fashion by upgrading cluster nodes one by one. Zero Downtime Upgrades Gray Minus Limited
Through dynamic auto-discovery mechanisms a cluster can be scaled up and down during runtime without further configuration. Elastic and linear scalability at runtime Gray Minus Limited
The auto-discovery leverages several discovery providers such as DNS, S3, etc. This gives you the possibility to choose your most favored approach for dynamic cluster discovery. Pluggable Auto-Discovery Gray Minus
Autoscaling can be leveraged in container environments such as kubernetes. There is a potential tradeoff between scaling triggered by events like resource utilization and the strain it can put on your overall systems (like authentication). Autoscaling support Gray Minus Limited
It reduces the rate of incoming messages and connection requests from publishing clients that significantly contribute to the overload of a cluster. This mechanism improves the resiliency of a HiveMQ cluster dramatically and allows a cluster to recover itself from stress situations without notable service degradation for most MQTT clients. Cluster Overload Protection Gray Minus
HiveMQ Control Center
The dashboard of the control center provides a clear overview of the current state of the HiveMQ cluster and its system metrics including CPU, Memory and Disk usage and other details. It provides insights on key MQTT relevant metrics such as number of connections and subscriptions, inbound and outbound message throughput, retained messages and queued messages. Notifications inform about latest warnings and errors and lead directly into drill down views to access relevant information quickly. Furthermore the status of your current license can be verified. Real-time monitoring Dashboard Gray Minus
It gives you a consolidated view of all MQTT sessions from all nodes in your cluster and provides an efficient way to sort, filter, and navigate through all sessions. On click connection, session, security, subscription and historic information and more details of a particular client session can be viewed. Furthermore clients can be disconnected and removed from the broker cluster. MQTT Client Drill-Down Analysis Gray Minus
It gives you access to all previous events associated with a selected client and makes it easier to monitor and analyze the behavior of a specific client over time and diagnose problems. Client Event History Gray Minus Gray Minus
The shared-subscription overview provides information for each shared subscription on your HiveMQ cluster. On click details about a shared subscription can be viewed and cross-links lead to clients details of participating clients. Shared Subscription Drill-Down Analysis Gray Minus
The retained message overview gives you a consolidated view of all retained messages from your cluster. The overview provides an efficient way to sort, filter, and navigate through all retained messages. On click details such as message and user properties, expiry information and payload metadata of a retained message can be examined. Retained Messages Drill-Down Analysis Gray Minus

Support for server side and mutual TLS with versions TLSv1, TLSv1.1, TLSv1.2 and TLSv1.3 TLS / SSL for MQTT
HiveMQ is built on the concept of extensions that can provide different types of authenticators to authenticate MQTT clients. You can build your own custom authentication extension or make use of our built-in Enterprise Security Extension that provides Basic Auth, SSL Cert or JWT based authentication methods. Pluggable Authentication
Similarly to the Authentication you can also build custom authorization or make use of our ESE to leverage its flexible and fine grained permission system. Authorization and Permissions
HiveMQ comes prepackaged with an OpenSSL implementation called BoringSSL which is maintained by Google and can be activated on Linux or MacOS X. The main advantage of using native SSL lies in its increased performance compared to standard JVM SSL and the availability of additional state-of-the-art cipher suites like a stronger AES with GCM, the CHACHA20 stream cipher, and additional cipher suites with elliptic curve algorithms. Native TLS / SSL Gray Minus Gray Minus
Online Certificate Status Protocol stapling allows the determination of the SSL certificate status by the HiveMQ broker. The broker regularly obtains an OCSP response about its own certificate from the OCSP responder, caches the response and sends it directly to the client in the initial TLS handshake. The client does not have to connect to the OCSP responder directly. This significantly reduces the load on the OCSP responder, since a single request per validity period is sufficient. A request per individual client is no longer necessary. OCSP Stapling Gray Minus Gray Minus Gray Minus
It provides an encrypted connection between the HiveMQ broker nodes to ensure privacy and data integrity. Anyhow as encryption requires additional computing load, best performances can be achieved by providing a security layer on top of TCP for the cluster, like a secure network zone for the HiveMQ cluster nodes. Secure cluster communication comes into play if such mechanisms are not possible or other individual security/regulation or law related requirements exist. Secure cluster communication with TLS / SSL Gray Minus Gray Minus Gray Minus
The audit log provides a single, unified log for tracking auditing-relevant data. It allows to access an overview of all actions that are performed and which information was accessed by whom and when. This can satisfy legal and compliance requirements. Furthermore can it be used to secure a HiveMQ cluster via intrusion-prevention software. Audit Logs Gray Minus Gray Minus Gray Minus
Connection Overload Protection determines the rate of MQTT CONNECT packets that HiveMQ allows per second. This is useful if your deployment makes use of external authentication and/or authorization systems that can only handle a certain average rate of authentications per second. Connection Overload Protection Gray Minus Gray Minus Gray Minus
The Handshake Overload Protection defines number of concurrent SSL handshake operations which can be used as an overload protection for the broker during bulk (re)-connection scenarios. Handshake Overload Protection Gray Minus Gray Minus Gray Minus
HiveMQ exposes a large set of MQTT related metrics including throughput in amounts and bytes and rates, counts and bytes per different MQTT message type. This enables you to monitor the health of your central MQTT messaging platform and to proactively identify anomalies, bottlenecks and other technical issues. MQTT Message Metrics
One option to expose the HiveMQ metrics is the usage of the Java Management Extensions (JMX) which enables the integration into a large set of JMX based Java monitoring tools. JMX Monitoring
In our Extension Marketplace we offer several open source monitoring extensions to seamlessly integrate into the most popular monitoring systems such as Prometheus, InfluxDB, or Datadog and leverage the large set of metrics that are exposed. We also offer a commercial extension into Splunk. Open Source Monitoring Extensions
HiveMQ offers more than 800 additional Monitoring metrics that allow you monitor the additional capabilities of our commercial editions, examples are metrics of the cluster communication or our cluster overload protection. These metrics extend the set of MQTT related metrics. 800+ Monitoring Metrics Gray Minus
