The short version

  • Each has a real cost: Nile limited to B2B SaaS use cases, not optimized for single-tenant applications; 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: Nile covers Multi-tenant virtualization, VerneMQ covers Erlang/OTP clustering.
  • Prices and features above were last checked on 31 August 2026.

  • An organisation that wants a broker maintained by a small European company rather than by a vendor that keeps changing licencesnot Nile

Where each one falls short

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

Nile

  • Limited to B2B SaaS use cases, not optimized for single-tenant applications
  • Query token abstraction makes pricing less transparent than traditional compute pricing
  • Free plan limited to 50M query tokens and 1GB storage for development
  • Serverless startup latency may impact performance-sensitive applications
  • Per-million token overages require careful monitoring to avoid surprise costs

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.

Answered from the vendors’ own pages

Nile: What are query tokens and how are they calculated?

Query tokens are abstract units of CPU and memory used when queries execute on Nile's serverless compute. The platform uses this abstraction to enable fair, predictable pay-per-use pricing.

Source
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.

Nile: Do all Nile plans include multi-tenant isolation?

Yes. All plans including the free tier include unlimited databases, tenants, and vector embeddings with built-in data isolation.

Source
VerneMQ: Is the project still maintained?

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

Nile: What is included in the Pro plan?

The Pro plan ($15/month) includes 150M query tokens, 5GB storage, 10,000 connections, and a 99.95% SLA. SAML and MFA authentication features are available on Pro and above.

Source
VerneMQ: Does it have a managed cloud?

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

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.
