# Airtable vs Supabase vs MySQL vs PostgreSQL: Which Should You Move To?

Deciding to leave Airtable is the easy part. The next question — *move to what?* — is where teams stall. Supabase, MySQL, and PostgreSQL all get suggested, and they are not really competing on equal terms. Here is how they actually differ, and why most Airtable migrations end up on Postgres (sometimes wearing a Supabase badge).

## Key takeaways
- Supabase is PostgreSQL with auth, APIs, and storage bundled on top — choosing it is choosing Postgres plus a platform.
- PostgreSQL maps onto Airtable concepts more cleanly than MySQL, thanks to JSONB, arrays, and generated columns.
- MySQL is a fine database, but rarely the reason to migrate unless your team already runs it.
- Migrating to plain Postgres first keeps every future option open — including moving to Supabase later with no rewrite.

## The contenders, briefly
**PostgreSQL** is the open-source relational database that has become the default choice for new applications. Rich types, strong standards support, huge ecosystem.

**Supabase** is not a different database — it is a managed platform *built on* PostgreSQL. Every Supabase project is a real Postgres database with an auto-generated REST and GraphQL API, authentication, and file storage layered on. If you migrate to Supabase, you are migrating to Postgres with batteries included.

**MySQL** is the other long-standing open-source relational database. Mature, fast, widely hosted — but with a thinner type system and historically weaker support for the JSON and constraint features that Airtable bases lean on.

## Side by side
| | Airtable | Supabase | MySQL | PostgreSQL |
| --- | --- | --- | --- | --- |
| What it is | Spreadsheet-database SaaS | Managed Postgres + platform | Relational database | Relational database |
| Underlying engine | Proprietary | PostgreSQL | MySQL | PostgreSQL |
| Built-in API & auth | Yes (limited) | Yes | No | No |
| JSON / array types | N/A | Native (JSONB, arrays) | JSON only | Native (JSONB, arrays) |
| Scale ceiling | Plan-capped | Very high | Very high | Very high |
| Best fit for Airtable teams | — | Want app features bundled | Already run MySQL | Want control & clean mapping |

## Why Airtable data lands best on Postgres
Airtable bases are full of the things PostgreSQL handles natively: multi-select fields (which map to arrays), loosely structured data (which fits JSONB), formula fields (which become generated columns), and rich linked relationships (which become foreign keys and junction tables). MySQL can do most of this too, but Postgres does it with less friction and stronger guarantees.

> Supabase vs plain Postgres: If you want an instant API, built-in auth, and file storage, Supabase saves you real work. If you want maximum control or already have an application layer, plain managed Postgres is leaner. Either way the data model is identical — so you are not locked in.

## Migrate once, keep your options open
Here is the practical insight that resolves most of the indecision: because Supabase *is* PostgreSQL, a plain Postgres database can be restored into Supabase — or any managed Postgres host — later, with no schema rewrite. So you do not have to make the perfect platform decision today. Migrate your Airtable base to clean, standard Postgres now, and you can move it to Supabase, a self-hosted instance, or a different cloud whenever it suits you.

That is also why MySQL is rarely the migration target for Airtable teams: it solves the same scale problem but without the clean conceptual mapping or the easy upgrade path to a managed platform like Supabase.

## How to choose, quickly
- **Want scale, control, and a clean migration?** Plain PostgreSQL.
- **Want Postgres plus auth, APIs, and storage out of the box?** Supabase.
- **Already standardised on MySQL across your stack?** MySQL is reasonable — but confirm it really fits your Airtable field types first.

## FAQ
**Is Supabase the same as PostgreSQL?** Supabase is built on PostgreSQL — every Supabase project is a full Postgres database with an auto-generated API, authentication, and storage layered on top. If you migrate to Supabase you are, underneath, migrating to PostgreSQL.

**Should I move from Airtable to MySQL or PostgreSQL?** For most Airtable migrations, PostgreSQL is the better target. Airtable bases lean heavily on rich field types, JSON-like data, and complex relationships, and Postgres handles those more gracefully than MySQL thanks to native JSONB, array types, generated columns, and stronger constraint support.

**What is the easiest database to migrate Airtable to?** PostgreSQL, because its data model maps cleanly onto Airtable concepts: tables to tables, linked records to foreign keys, and field types to columns. Purpose-built tooling like AT Migrator automates that mapping.

**Can I move to Supabase later if I migrate to plain Postgres now?** Yes. Because Supabase is standard PostgreSQL, a plain Postgres database can be restored into Supabase (or any managed Postgres host) later with no schema rewrite.
