The short version

  • EMQX has a free plan, then $234/mo; GitHub Copilot starts at $10/mo.
  • Only EMQX lists erlang clustering; only GitHub Copilot lists code completion.
  • Where GitHub Copilot falls short: agent mode lacks deep tool orchestration and iterative execution compared to specialized agentic tools.
  • Prices and features on this page were last checked on 31 August 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

GitHub Copilot

  • Agent mode lacks deep tool orchestration and iterative execution compared to specialized agentic tools
  • Suggestions for niche or specialized programming languages are less accurate due to limited training data
  • Less effective with non-English prompts or grammatically incorrect developer instructions
  • Free tier severely limited to 2,000 completions and 50 chat requests per month

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.

GitHub Copilot: Does GitHub Copilot have a free tier?

Yes. GitHub Copilot Free offers 2,000 code completions and 50 chat requests per month at no cost with no credit card required. Students and open-source maintainers get free Pro access.

EMQX: Can I run a free cluster?

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

GitHub Copilot: What IDEs and editors are supported?

GitHub Copilot works in VS Code, Visual Studio, JetBrains IDEs (IntelliJ, PyCharm, WebStorm), Vim, Neovim, and Azure Data Studio with extensions providing code suggestions and chat capabilities.

Source
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.

GitHub Copilot: What programming languages does Copilot support?

Copilot supports more than 10 core languages including JavaScript, TypeScript, Python, Java, C#, Go, and Rust. Performance is strongest for these popular languages with extensive open-source training data.

Source
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.

GitHub Copilot: How does the free tier compare to paid plans?

Free tier limits completions and chat to 2,000 and 50 per month. Pro ($10/month) offers unlimited completions, while Pro+ ($39/month) adds access to frontier AI models and agent mode for autonomous multi-file edits.
