The short version

  • Each has a real cost: Airtable hitting a plan limit blocks adding records or attachments entirely until you upgrade, rather than degrading gracefully; 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.
  • They diverge on capability: Airtable covers Spreadsheet-database hybrid, EMQX covers Erlang clustering.
  • Prices and features above 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.

Airtable

  • Hitting a plan limit blocks adding records or attachments entirely until you upgrade, rather than degrading gracefully
  • Team is $20 per user per month and Business $45, both at the annual rate
  • Automation and API usage are capped by plan
  • Enterprise Scale pricing is not published

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.

Answered from the vendors’ own pages

Airtable: Is there a free Airtable plan and what does it include?

Yes, Airtable's Free plan is indefinite with unlimited bases, 1,000 records per base, up to 5 editors, 1 GB storage per base, 100 automation runs per month, and core features like Interface Designer and mobile apps.

Source
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.

Airtable: How does Airtable handle permissions and viewers?

Airtable charges per editor only. Read-only viewers, form submitters, and people accessing share links are free on every plan, making it cost-effective for large viewing audiences.

Source
EMQX: Can I run a free cluster?

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

Airtable: What are Airtable's record limits?

Free plan has 1,000 records per base, Team plan has 50,000, Business plan has 125,000, and Enterprise Scale has 500,000+ records. Performance degrades past 100,000 records in a single base.

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.

Airtable: Can Airtable integrate with other tools like Slack?

Yes, Airtable integrates with Slack via Zapier or Make.com, allowing automation like sending Slack messages when records are created or updated. Airtable also has a native API for direct integrations.

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.
