The short version

  • Only HiveMQ has a free tier, so it costs nothing to try first.
  • Each has a real cost: HiveMQ the Community Edition lacks clustering, persistence extensions, the control centre and all enterprise bridges, so a prototype built on it does not become production by buying support.; Ubiquiti UniFi product page states no licensing fees but publishes no hardware price; buyers must go to the Ubiquiti Store or an authorized distributor for a figure
  • Prices and features above were last checked on 31 August 2026.

Where each one falls short

Documented limitations, not opinions. Every one is a constraint you would hit in normal use.

HiveMQ

  • The Community Edition lacks clustering, persistence extensions, the control centre and all enterprise bridges, so a prototype built on it does not become production by buying support.
  • The entry commercial tiers cap at ten thousand connections, and device fleets grow, so the step to Enterprise capacity pricing arrives sooner than most projects plan for.
  • It is a JVM application, so memory tuning and garbage collection behaviour become the operator’s problem at high connection counts, unlike the C-based brokers in this space.
  • Extensions are written in Java against HiveMQ’s SPI, which means custom authentication logic is locked to the platform and cannot move to another broker.
  • For simple use cases it is substantially heavier and more expensive than Mosquitto or EMQX, and small deployments frequently pay enterprise prices for clustering they never use.

Ubiquiti UniFi

  • Product page states no licensing fees but publishes no hardware price; buyers must go to the Ubiquiti Store or an authorized distributor for a figure
  • Newest WiFi 7 access points such as the U7 Pro require compatible UniFi controller hardware or cloud console to manage centrally

Can I use HiveMQ for free?
Yes. HiveMQ has a free tier, so you can try it without paying. Ubiquiti UniFi starts at On request.
What is HiveMQ best used for?
HiveMQ is most often used for a connected vehicle fleet where devices drop off the network for hours and sessions must survive, an industrial plant bridging mqtt telemetry into kafka without writing and operating the bridge, a utility that needs message-level schema validation so one faulty firmware release cannot corrupt the data lake, an iot project that needs a self-managed broker price for a budget submission without entering a sales process. Of those, a connected vehicle fleet where devices drop off the network for hours and sessions must survive and an industrial plant bridging mqtt telemetry into kafka without writing and operating the bridge are not what Ubiquiti UniFi is typically brought in for.
