Can I suspend cluster usage to save on costs?

A running cluster, though idle, would still incur costs. Please delete the cluster to stop billing for that cluster.

At the moment, only the HiveMQ Cloud Starter cluster is billed hourly.

It is not possible to suspend a cluster (preserving customized settings) at the moment.

To save on costs, you can delete the cluster, and it will not be billed starting from the moment of deletion.
