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).
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. The mechanics of that mapping are covered in our step-by-step migration guide.
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.
