Airtable to Supabase
Supabase gives you Postgres plus the surrounding pieces an Airtable base was implicitly using: an API, auth, file storage, and scheduled jobs. The migration is mostly about doing those explicitly.
This is a generalised method, not a client case study. No client names, schemas, data, or outcomes are published here, and no results are claimed on a client's behalf.
What is airtable to Supabase migration?
Supabase gives you Postgres plus the surrounding pieces an Airtable base was implicitly using: an API, auth, file storage, and scheduled jobs. The migration is mostly about doing those explicitly.
Method
- Create the schema from the field mapping, with grants written in the same migration as the tables.
- Enable row-level security on every table and write policies from the permission parity work.
- Move attachments into Supabase Storage with a bucket policy that matches the table policy.
- Replace Airtable API consumers with PostgREST calls or server functions, and rotate the old keys.
- Recreate scheduled automations with pg_cron or an external scheduler calling a verified endpoint.
create table public.invoices (
id uuid primary key default gen_random_uuid(),
org_id uuid not null,
airtable_record_id text unique,
amount numeric(14,2) not null,
created_at timestamptz not null default now()
);
grant select, insert, update, delete on public.invoices to authenticated;
grant all on public.invoices to service_role;
alter table public.invoices enable row level security;
create policy "org members read own invoices"
on public.invoices for select to authenticated
using (org_id = (select org_id from public.memberships where user_id = auth.uid()));Failure modes
- Creating tables without grants, so the API returns permission errors that look like RLS problems.
- Storage buckets left public while the table is locked down.
- Old Airtable personal access tokens left active after cutover.
How it is verified
- Anonymous requests are refused on every table that should be private.
- A storage object is unreachable for a user who cannot read its row.
