Erlang MQTT broker for large IoT fleets, relicensed to BSL with production free use limited to one node

The short version
- Each has a real cost: EMQX the move to Business Source Licence 1.1 at version 5.9 in May 2025 limits free production use to a single node, so the clustering that justifies choosing EMQX now requires a paid subscription from the second node onward.; Ninox free plan limited to 5 users and 5,000 records

Where each one falls short
Documented limitations, not opinions. Every one is a constraint you would hit in normal use.
EMQX
- The move to Business Source Licence 1.1 at version 5.9 in May 2025 limits free production use to a single node, so the clustering that justifies choosing EMQX now requires a paid subscription from the second node onward.
- The relicensing arrived in a minor release, which caught users who had pinned to 5.x expecting Apache 2.0 terms and forced legal review of existing deployments.
- Running an Erlang/OTP cluster well requires operational knowledge most teams do not have, and diagnosing distribution, mnesia or memory issues means learning a runtime you use for nothing else.
- Enterprise pricing is quoted rather than published for the self-managed edition, so the cost of the clustered configuration you actually need is invisible until you talk to sales.
- The Serverless tier caps at around a thousand connections and shares infrastructure, which makes it a prototyping tier rather than a genuine small production option.
Ninox
- Free plan limited to 5 users and 5,000 records
- API call limits restrict automation on lower tiers (1,000/month free, 10,000/month team)
- Only 7-day history on free plan vs. unlimited on Business

Questions people ask
- Is EMQX or Ninox better?
- Neither clearly leads. EMQX starts at Free and Ninox at Free, and user ratings are close enough to be indistinguishable. Choose on capability and platform support.
- Which is cheaper, EMQX or Ninox?

- Can I use EMQX for free?
- Both have a free tier, so you can try either at no cost before committing.
- What is EMQX best used for?
- EMQX is most often used for a connected vehicle platform needing millions of persistent mqtt sessions with quic for handover across mobile networks, an industrial operator routing sensor telemetry straight into timescaledb or kafka without writing a consumer service, an iot product team that has outgrown a single mosquitto instance and needs clustering and shared subscriptions, a smart building deployment mixing mqtt, coap and lwm2m devices on one broker. Of those, a connected vehicle platform needing millions of persistent mqtt sessions with quic for handover across mobile networks and an industrial operator routing sensor telemetry straight into timescaledb or kafka without writing a consumer service are not what Ninox is typically brought in for.
