Comparison · Airtable vs. Custom App

Outgrowing Airtable? Here's when a custom app is worth it

You built your operations in Airtable (or a spreadsheet before it), and it worked. Now more people edit, the base is getting heavy, and the workarounds are piling up. Here's what each path costs and where each one fits, including when staying put is the better call.

Airtable vs. a custom app: side by side

Where Airtable has the edge, the table says so.

Airtable vs. custom app, compared factor by factor
Factor	Airtable	Custom app (ArdinGate)
Upfront cost	None; there's a free plan	$6,000–$11,000 once
Monthly cost	$20 (Team) or $45 (Business) per editor, billed annually¹	$60/mo hosting, the same at any team size
Time to start	Minutes	Weeks, after a discovery call and written scope
Changing the structure	Anyone with access can add a field or view today	Changes go through a developer (Care hosting adds an hour of content edits a month; new features are quoted separately)
Rules and permissions	Set per base, view and interface	Built around your roles and steps, enforced on every screen
Size limits	Per-base record, storage and automation caps by plan	Your own database, sized to the server
Your data	CSV per table or view; automations and interfaces stay behind	Your database and your code, portable to any host

The five-year math at ten editors

Each plan is priced per editor at its annual-billing rate. The custom side is a focused web app ($6,000–$11,000) plus $60/mo Core hosting for the same period. Set the team size to the number of people who actually edit, not everyone who looks.

Team size Years

Airtable vs a custom app for 10 users over 5 years
Option	How it's priced	Total	Verdict
Airtable Team¹	$20 per user / mo	$12,000	About even
Airtable Business¹	$45 per user / mo	$27,000	Custom costs less
Custom build (ArdinGate)	$6,000–$11,000 once + $60/mo hosting	$9,600–$14,600	You own it

Each plan at its cheapest published rate (usually billed annually), plus required onboarding fees. Prices checked October 2026; vendors change them, so confirm on their pricing page. Your quote is fixed after a short discovery call.

At ten editors over five years, Airtable Business comes to $27,000 against $9,600–$14,600 for a custom app, so a custom build costs less. Team comes to $12,000, and the two come out about even.

With only a few editors, the answer flips. At three editors, Team comes to $3,600 and Business to $8,100: at this size, the subscription costs less on either plan. Business passes the top of the custom range at 6 editors; Team at 13. So the deciding number isn't the size of your company, it's how many people need to change records.

Who counts as a paid seat

On Team and Business, Airtable bills every user who has edit permission on at least one base in the workspace. Read-only collaborators, form submissions and share links are free¹.

That's a fair model, and it works in your favor while most people only look or fill in forms. It scales against you as the base becomes where the work happens: once the office, the field leads and the bookkeeper all update records, each of them is a seat. Charges are prorated when you add someone mid-term. A custom app has no per-user charge; adding the tenth or the fortieth login costs nothing extra.

Team, Business and the limits you hit

Airtable sets limits per base, by plan. According to its plans overview (checked October 2026), Team allows 50,000 records and 20GB of attachments per base, 100 automations per base, and 100,000 API calls per workspace a month. Business raises that to 125,000 records, 100GB of attachments and 150 automations per base, with no monthly API cap². If you go over the record or attachment limits, Airtable keeps your data and your bases keep working, but you can't keep growing past the cap on that plan.

Those limits are usually what pushes a team from Team to Business, along with two features Business adds: two-way sync between bases and an admin panel for managing users across the workspace. The move more than doubles the per-editor price, from $20 to $45¹.

The other limit is structural. Airtable is a flexible database with views on top. When the work needs enforced steps (a job can't close until it's inspected), permissions that differ by record, or screens built for one task, teams end up layering interfaces, automations and scripts to get there. A custom app builds those rules in directly, on a database you own.

When Airtable is the right call

For a lot of teams, Airtable is the better choice:

Only a few people edit. At three editors, Team comes to $3,600 over five years (subscription costs less), and read-only users are free.
You need it today. You can go from idea to working base in an afternoon, with no build and no scope.
Your process is still changing. Adding a field or a new view takes seconds, and anyone on the team can do it. That flexibility is worth a lot while you figure out how you work.
You're comfortably under the limits. If your bases sit well below the record and automation caps, those limits never touch you.
The work is mostly tracking. Lists, statuses, calendars and kanban views are where Airtable shines.

A custom app pays off when the editor count climbs, the base runs into its caps, or the workarounds start costing more time than the tool saves. Airtable is also a great way to prototype: a base you've lived in for a year is the best spec a custom build can have.

Moving off Airtable

Any view can be downloaded as a CSV from the menu next to the view name, with every field visible in that view. Airtable doesn't export a whole base as one file, so each table comes out as its own CSV; use an unfiltered view with every field showing so nothing is left out. Record comments, field descriptions and data stored only in extensions aren't included.

Attachments come out as file names and links, and those links expire after a few hours, so the files get pulled down as part of the move rather than later. The CSVs are mapped into the new app's database during the build, linked records become real relationships, and your records are there on launch day. Automations, interfaces and formulas don't come across as data; they become features of the app, built to match how you work.

The verdict

Bottom line on Airtable vs. custom

Count your editors. At ten, Airtable Business comes to $27,000 over five years and Team to $12,000, against $9,600–$14,600 for a custom app: on Business, a custom build costs less; on Team, the two come out about even. At three editors, Airtable costs less on either plan, and if it fits, stay on it.

Beyond price, decide on fit and ownership: whether your process needs rules a base can't enforce, whether you're near the caps, and who holds the system your business runs on. After launch, Care hosting ($100/mo) adds an hour of content edits a month; new features are quoted separately. See how a custom web app build works →

Questions about Airtable vs. a custom app

Is a custom app cheaper than Airtable?

It depends on how many people edit. At 10 editors over five years, Airtable Business comes to $27,000 and Team to $12,000, against $9,600–$14,600 for a custom app on Core hosting. On Business, a custom build costs less; on Team, the two come out about even. With 3 editors, Team comes to $3,600 and Business to $8,100, so Airtable costs less on either plan.

Who counts as a paid seat in Airtable?

On Team and Business, you pay for every user with edit permission on at least one base in the workspace. Read-only collaborators, form submissions and share links are free. So a team where most people only view or submit forms can stay inexpensive; a team where everyone updates records pays for everyone.

Can I bring my Airtable data over?

Yes. Any view can be downloaded as a CSV from the menu next to the view name, with every field visible in that view. There's no single-file export for a whole base, so each table comes out as its own CSV. Record comments, field descriptions and data held only in extensions aren't included, and attachments come out as file names with links that expire after a few hours, so files get downloaded separately. The CSVs are mapped into the new app's database during the build, including the links between tables.

Should I just stay on Airtable?

If a few people edit, you're well under the plan limits, and your views and automations cover how you work, yes. A custom app makes sense when the editor count climbs, you hit the per-base limits, or the work needs rules, permissions and screens that a spreadsheet-style base can't enforce.

Can AI be added to a custom app?

Yes. If you already use an AI service (OpenAI, Claude, Gemini, or any provider with an API), it can be connected to your app to summarize notes, draft emails and replies, or answer questions about your records. You keep your own account and pay the provider directly for usage, and nothing it suggests changes your data until someone on your team approves it. Adding it runs $2,500–$6,000.
