Erlang MQTT broker whose source is Apache 2.0 but whose official binaries need a paid subscription

The short version

  • Each has a real cost: MySQL hot online backup is not in the free Community Server; MySQL Enterprise Backup is a paid Enterprise Edition component; 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: MySQL covers ACID compliance, VerneMQ covers Erlang/OTP clustering.
  • Prices and features above were last checked on 31 August 2026.

VerneMQ

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

Where each one falls short

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

MySQL

  • Hot online backup is not in the free Community Server; MySQL Enterprise Backup is a paid Enterprise Edition component
  • Transparent Data Encryption, data masking and de-identification are Enterprise Edition only
  • MySQL Enterprise Firewall, which guards against SQL injection, and MySQL Enterprise Audit are both paid components
  • External authentication against PAM or Windows Active Directory requires MySQL Enterprise Authentication
  • The thread pool ships as MySQL Enterprise Scalability rather than in the community build

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.
