The short version

  • Only Airtable has a free tier, so it costs nothing to try first.
  • Each has a real cost: Airtable hitting a plan limit blocks adding records or attachments entirely until you upgrade, rather than degrading gracefully; Knack plans are capped by stored records, so an application that logs events or keeps history rather than current state climbs tiers on data volume alone, and archiving old records becomes a permanent maintenance chore rather than a one-off.
  • They diverge on capability: Airtable covers Spreadsheet-database hybrid, Knack covers Visual database builder.
  • Prices and features above were last checked on 30 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

Knack

  • Plans are capped by stored records, so an application that logs events or keeps history rather than current state climbs tiers on data volume alone, and archiving old records becomes a permanent maintenance chore rather than a one-off.
  • API access is capped per day, at 1,000 calls on the entry plan and 10,000 at the Corporate tier, so a scheduled sync or a busy automation can exhaust the day's quota before the working day ends and integrations then fail silently.
  • The application itself cannot be exported or self-hosted; records can be downloaded but the pages, roles, flows and business logic exist only inside Knack, so outgrowing the platform means rebuilding the app rather than moving it.
  • Customisation beyond the builder is limited to injected CSS and JavaScript that Knack's support does not cover, so any non-standard interface behaviour becomes yours to maintain against a DOM the vendor can change without warning.
  • Compliance capabilities that regulated buyers assume are baseline, HIPAA and GovCloud options, advanced SSO, IP restrictions and private environments, are gated to the Corporate and Enterprise tiers, so a small regulated pilot cannot legitimately start on an entry plan.

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
Knack: Is Knack charged per user?

No. User accounts are unlimited on all plans. Plans are bounded by stored record count, file storage, API calls per day and automation transactions.

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
Knack: What happens when I exceed the record limit?

You move to a higher tier or reduce stored records. Because the limit is on data rather than people, apps that accumulate history hit it while apps that track a fixed set of entities generally do not.

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
Knack: Can I export my application or self-host it?

You can export record data. The application itself, its pages, roles, permissions and flows, is not exportable and cannot be self-hosted, so leaving means rebuilding elsewhere.

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
Knack: Is it suitable for public-facing portals?

That is its strongest case, because logins are unlimited and role-based permissions are built in. The constraint is record volume and API throughput, not audience size.

Knack: Can I use it for regulated data?

HIPAA-aligned and government cloud options exist but only on the Enterprise tier, along with private server environments. Lower tiers should not be used for regulated workloads.
