The short version

  • Each has a real cost: Podman native support is Linux-first; macOS and Windows run containers inside a managed virtual machine, which adds a layer Docker Desktop users may not expect; VerneMQ the official binaries and Docker images are not Apache 2.0 but sit under a EULA requiring a yearly commercial subscription, a distinction easy to miss and awkward to discover during a licence audit.
  • They diverge on capability: Podman covers Daemonless architecture, VerneMQ covers Erlang/OTP clustering.
  • Prices and features above were last checked on 31 August 2026.

What people use each for

The jobs each tool is most often brought in to do.

VerneMQ

  • An industrial operator that wants an MQTT broker with predictable memory behaviour and no data integration features it will not usenot Podman
  • A team building from source to stay strictly under Apache 2.0 terms with no vendor licence entanglementnot Podman
  • A deployment needing custom authentication logic implemented as a plugin in Lua or over a webhooknot Podman
  • An organisation that wants a broker maintained by a small European company rather than by a vendor that keeps changing licencesnot Podman

Where each one falls short

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

Podman

  • Native support is Linux-first; macOS and Windows run containers inside a managed virtual machine, which adds a layer Docker Desktop users may not expect
  • Docker Compose support arrives through a compatibility layer rather than natively, and complex Compose files can hit gaps
  • Rootless mode has real constraints around privileged ports and some storage drivers
  • Smaller ecosystem of tutorials and third-party integrations than Docker, so unusual problems have fewer existing answers

VerneMQ

  • The official binaries and Docker images are not Apache 2.0 but sit under a EULA requiring a yearly commercial subscription, a distinction easy to miss and awkward to discover during a licence audit.
  • Octavo Labs is a very small company, so support depth, response times and the bus factor on the codebase are materially thinner than at HiveMQ or EMQ.
  • There is no data integration or rule engine layer, so routing messages into a database means writing and operating your own consumer service.
  • Operating an Erlang cluster requires runtime knowledge that most teams do not have and will use for nothing else in their stack.
  • There is no vendor-managed cloud offering, so every deployment is self-operated with the infrastructure and on-call cost that implies.

Can I use Podman for free?
Both have a free tier, so you can try either at no cost before committing.
What is Podman best used for?
Podman is most often used for running containers on hosts where a root daemon is not acceptable, replacing docker on linux without retraining a team on new commands, managing containers as systemd services on a single server, building locally in a way that maps onto kubernetes pods. Of those, running containers on hosts where a root daemon is not acceptable and replacing docker on linux without retraining a team on new commands are not what VerneMQ is typically brought in for.

Answered from the vendors’ own pages

Podman: Is Podman free?

Yes. Podman is open source with no licence fee, for personal or commercial use.

VerneMQ: Is VerneMQ free?

The source is Apache 2.0 and free. The official binary packages and Docker images are covered by a separate EULA that expects a yearly fee for commercial use.

Podman: Can Podman replace Docker?

For most everyday use, yes. The CLI is deliberately Docker-compatible and many teams alias docker to podman. Gaps appear mainly around Docker Compose and Docker Desktop-specific features.

VerneMQ: Is the project still maintained?

Yes. Octavo Labs AG in Zurich continues to publish 2.x releases, most recently in 2026.

Podman: What does daemonless actually mean?

Docker runs a central background service as root that owns every container. Podman does not: each container is a child process of the user who ran it, so containers can run without root privileges at all.

VerneMQ: Does it have a managed cloud?

No. Every deployment is self-hosted, with commercial support available from Octavo Labs.

Podman: Does Podman work on macOS?

Yes, but through a managed Linux virtual machine, because containers are a Linux kernel feature. That is the same approach Docker Desktop takes.

VerneMQ: How does it compare to EMQX?

Narrower in features and without a rule engine, but with a simpler licence story for source builds after EMQX moved to BSL.
