Supabase

Startups building real SaaS products use Supabase as their production backend: Postgres for data, row-level security for multi-tenant permissions, built-in auth, and edge functions for server-side logic. It replaces the usual "Firebase plus a stack of glue" setup while keeping developers on SQL, which makes the eventual handoff to a data team far easier.

Operations teams outgrowing Airtable migrate reporting and internal tool data to Supabase when they need joins across millions of rows, real database constraints, or direct BI/warehouse access — while still keeping a no-code front end (Softr, Retool, a custom Next.js app) on top. This is the usual exit path when "Airtable as a database" stops scaling.

Agencies ship client apps on Supabase when the project needs genuine user accounts, file storage, and custom logic but does not justify a bespoke backend team. Pairing Supabase with Next.js has become one of the fastest stacks for turning a scoped engagement into a maintainable product.
