Consul vs HiveMQ
HiveMQ
Networking
Enterprise MQTT broker for industrial IoT with a published self-managed price list
- From
- Free
- Rated
- -
The short version
- Each has a real cost: Consul namespaces, admin partitions and other multi tenancy controls are Consul Enterprise only; 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.
- They diverge on capability: Consul covers Service discovery, HiveMQ covers MQTT 5 and 3.1.1.
- Prices and features above were last checked on 31 August 2026.
Where they differ
Only the attributes on which Consul and HiveMQ actually diverge.
Identical on both: starting price (Free), free tier (Yes), user rating (Not yet rated), category (Networking).

- An IoT project that needs a self-managed broker price for a budget submission without entering a sales processnot Consul
Where each one falls short
Documented limitations, not opinions. Every one is a constraint you would hit in normal use.
Consul
- Namespaces, admin partitions and other multi tenancy controls are Consul Enterprise only
- Audit logging, OIDC authentication and FIPS 140-2 builds require Consul Enterprise, so compliance driven deployments cannot use the free edition
- Automated backups, redundancy zones, read replicas and automated server upgrades are Enterprise only
- Long Term Support releases are Enterprise only, so community users must upgrade to stay supported
- Service mesh and advanced traffic management sit in the Premium Enterprise tier above Standard Enterprise
- HashiCorp does not publish a Consul rate on its pricing page, which lists per resource prices for Terraform instead
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.

Questions people ask
- Is Consul or HiveMQ better?
- Neither clearly leads. Consul starts at Free and HiveMQ at Free, and user ratings are close enough to be indistinguishable. Choose on capability and platform support.
- Which is cheaper, Consul or HiveMQ?
- Consul starts at Free and HiveMQ at Free.
- Does Consul or HiveMQ run on more platforms?
- Consul runs on Linux, Windows, Mac, Cloud. HiveMQ runs on Linux, Docker, Kubernetes, Web.
- Can I use Consul for free?
- Both have a free tier, so you can try either at no cost before committing.
- What is Consul best used for?
- Consul is most often used for service discovery and health checking across dynamic infrastructure, running a service mesh with mutual tls between services, distributed key value configuration storage for applications. Of those, service discovery and health checking across dynamic infrastructure and running a service mesh with mutual tls between services are not what HiveMQ is typically brought in for.
- What can Consul do that HiveMQ cannot?
- Consul covers Service discovery, Health checking, Key/value store, Multi-datacenter. HiveMQ covers MQTT 5 and 3.1.1, Native clustering, Data Hub, Extension framework.
Answered from the vendors’ own pages
Consul: How much does Consul cost?
Consul does not publish specific pricing. The open source Community edition is free. HashiCorp also offers a Consul Enterprise edition, but pricing details are not disclosed publicly and must be obtained by contacting HashiCorp sales.
SourceHiveMQ: Is HiveMQ free?
The Community Edition is Apache 2.0 and free, but it has no clustering and none of the enterprise extensions.
Consul: Is Consul open source?
Consul includes a free, open source Community edition. HashiCorp also offers a proprietary Enterprise edition for organizations requiring advanced features, but no public pricing is available for the Enterprise version.
SourceHiveMQ: What does the commercial version cost?
Self-managed Launch is 299 US dollars a month for ten thousand connections; Run is 499 with higher throughput.
HiveMQ: Does it support MQTT 5?
Yes, both MQTT 5 and 3.1.1, including shared subscriptions and session expiry intervals.
HiveMQ: Can it bridge into Kafka?
Yes, via a commercial enterprise extension, not in the Community Edition.
