The clustering capability is what sets HiveMQ apart from everything else we tested before committing. Scaling broker nodes horizontally without any message loss or connection disruption during peak device activity is something we genuinely took for granted until we tried replicating it on an alternative platform during an evaluation. The extension SDK has also given our team the ability to build custom authentication and data transformation logic directly into the broker layer without compromising the core stability we depend on.

The team is helpful and always responsive whenever we have issues

I appreciate HiveMQ for its data replication through cluster management, which ensures that no messages are lost and everything is processed according to the quality of service set. It's built by extremely smart people who understand MQTT 3 and 5 features, making it extremely easy to implement and maintain. The system is robust and has a customer-first mindset, which is truly commendable. HiveMQ does an exceptional job at managing data for several hundred thousand actively connected devices.
