The short version

  • GitLab is a complete DevOps platform, delivered as a single application.
  • GitLab is free; EMQX starts at $234/mo.
  • Only EMQX lists erlang clustering; only GitLab lists git repository management.
  • Where GitLab falls short: baseline requires 8 vCPU and 16 GB RAM for single-node installations; resource-intensive.
  • Prices and features on this page were last checked on 13 November 2026.

Where each one falls short

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

EMQX

  • The move to Business Source Licence 1.1 at version 5.9 in May 2025 limits free production use to a single node, so the clustering that justifies choosing EMQX now requires a paid subscription from the second node onward
  • The relicensing arrived in a minor release, which caught users who had pinned to 5.x expecting Apache 2.0 terms and forced legal review of existing deployments
  • Running an Erlang/OTP cluster well requires operational knowledge most teams do not have, and diagnosing distribution, mnesia or memory issues means learning a runtime you use for nothing else
  • Enterprise pricing is quoted rather than published for the self-managed edition, so the cost of the clustered configuration you actually need is invisible until you talk to sales
  • The Serverless tier caps at around a thousand connections and shares infrastructure, which makes it a prototyping tier rather than a genuine small production option

GitLab

  • Baseline requires 8 vCPU and 16 GB RAM for single-node installations; resource-intensive
  • PostgreSQL is mandatory; no support for alternative databases
  • Redis or Valkey cache required; adds infrastructure complexity
  • High-availability deployments require inter-node latency below 5 ms; difficult to achieve across geographically distributed sites
  • Requires self-hosting and maintenance; GitLab.com SaaS only available to GitLab team members for administration

Questions people ask

Is EMQX or GitLab better?
Neither clearly leads. EMQX starts at Free and GitLab at Free, and user ratings are close enough to be indistinguishable. Choose on capability and platform support.
Which is cheaper, EMQX or GitLab?

Answered from the vendors’ own pages

EMQX: Is EMQX still open source?

Not in the OSI sense since version 5.9. It is source-available under Business Source Licence 1.1, reverting to Apache 2.0 four years after each release.

EMQX: Can I run a free cluster?

No. The additional use grant permits free production use of one node; clustering requires a commercial licence.

EMQX: What changed for existing users?

Community and enterprise editions merged, so all features are now visible, but the licence terms tightened in the same minor release.

EMQX: Which version is still Apache 2.0?

Releases before 5.9 remain under Apache 2.0, and each BSL release converts to Apache 2.0 four years after publication.
