Where each one falls short
Documented limitations, not opinions. Every one is a constraint you would hit in normal use.
Grist
- Business plan has minimum 5-user requirement
- Enterprise self-hosted pricing not disclosed publicly
- Annual billing discount only 20%, lower than some competitors
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.
