It's really all about scalability for us. We were running load test for new over the air update feature and i was honestly waiting for whole thing to crash. But HiveMQ just kept chugging along without breaking sweat. Clustering is phenomenal and we just spun up another node and it joined the party seamlessly. It handled backpressure from our downstream service gracefully too. Review collected by and hosted on G2.com.

Complexity of security setup is what i keep tripping over. We wanted to implement pretty strict X.509 client certificate authentication but getting mapping and validation rule right was pain. Documentation covers it, but it's bit scattered. Review collected by and hosted on G2.com.

I like using HiveMQ as our central hub for MQTT broker because it provides secure and reliable communication between IoT devices and applications. The best part about it is handling real-time message communication and its AI feature, which adds a cherry on the top. I appreciate its easy-to-use UI, which is user-friendly even for newcomers to HiveMQ. There's an AI assistant to help if I face any errors, making the overall experience quite smooth. The initial setup is also simple, which is a big plus for me. Review collected by and hosted on G2.com.

Like overall experience of mine is good but one thing that I supposed to be improved is to provide some learning material for some features that are advanced. Review collected by and hosted on G2.com.

HiveMQ has been one of the most reliable MQTT brokers we've used. Setting up secure connections was straightforward, and once everything was configured it required very little maintenance. It handles a high number of device connections without noticeable performance issues, and the monitoring tools make it easy to understand what's happening across the platform.

The initial learning curve can be a bit steep if you're new to MQTT or large-scale IoT deployments. Some advanced configuration options also require spending time with the documentation before you fully understand how everything fits together. Review collected by and hosted on G2.com.

Honestly, the biggest win for me is just the peace of mind. The clustering is so rock-solid that we never really worry about the system crashing.

Using their shared subscriptions feature has been a total game-changer compared to our old setup.

Connecting it to our existing company logins went super smooth. It’s just a great feeling knowing our whole data stream is secure, stable, and won't buckle under pressure. Review collected by and hosted on G2.com.

When something does go wrong, the error messages it spits out are massive walls of text. It can be a real headache to read through and figure out what actually broke. Review collected by and hosted on G2.com.

HiveMQ Control Center is one of the most useful feature. It gives my team this detailed look at individual client behaviors. For eg we could actually see which specific hardware batches were causing latency spikes. It's like a high end diagnostic dashboard that also happens to be a very solid broker. We haven't had a single missing telemetry packet since the migration and that makes our dispatchers much happier. Review collected by and hosted on G2.com.

In starting we actually struggled with the first cluster configuration especially around the security extension framework. It's very powerful don't get me wrong but the documentation feels a bit too technical like its written by engineers for engineers who already have a PhD in MQTT.

We were dealing with a specific integration where thousands of sensors on the assembly line had to sync simultaneously and most brokers we've tried just choked. With HiveMQ Control Center i can actually see the client sessions in real time which made debugging our OpenFeign client connections to the backend way less of a guessing game. It feels clean and professional. Its Extension SDK let us build a custom bridge to our legacy monitoring system without having to hack the core logic. Review collected by and hosted on G2.com.

We struggled with the XML based config at first because it's just so verbose. One tiny typo and the whole node refuses to join the cluster. I also wish the documentation had more real world examples for complex bridging scenarios instead of just the basic hello world stuff. Review collected by and hosted on G2.com.

I have used HiveMQ to analyze a large amount of data for personal AI tests and then use those insights to make decisions and write reports. I liked the option of running HiveMQ on my own infrastructure, which gave me plenty of control. I think $300/month was a fair price for self-hosting, and it was perfect for our test. The documentation is very helpful, and the customer support, as well as the community, are also very helpful. Review collected by and hosted on G2.com.

I think everything works well. The only frustrating thing is that some of the "cooler" features are locked behind the Enterprise plan, which I suppose is way more expensive than the Launch plan I used. Review collected by and hosted on G2.com.

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.

Pricing conversation with the sales team takes longer than it should for teams that just want to get started quickly. Review collected by and hosted on G2.com.

The broker stability at high message volumes is where HiveMQ genuinely earns its reputation. We push millions of messages daily across connected devices and the platform has not flinched once. Clustering was straightforward to configure and the reliability we have seen in production has given our engineering team a lot of confidence. Review collected by and hosted on G2.com.

The pricing structure can feel steep for teams that are still scaling up. Getting full access to enterprise features requires a commitment that smaller engineering teams might hesitate over. The documentation is solid but some of the more advanced configuration guides assume a level of familiarity that newer IoT developers may not have yet. Review collected by and hosted on G2.com.

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.

I wish HiveMQ created a 'HiveMQ MQTT Client' for C#/.NET. They have support only for Java which limits flexibility. Also, it would be nice if HiveMQ supported SYS topics for debugging and development with their professional and enterprise licenses. Review collected by and hosted on G2.com.
