Supabase
Development
Supabase is the open-source Firebase alternative, built on Postgres. We design and ship production Supabase backends: authentication, row-level security, realtime, and multitenant SaaS, plus clean migrations off Firebase when an app outgrows it.

Postgres, not a black box
Underneath Supabase is real Postgres: SQL, joins, constraints, and views, plus every Postgres tool you already know. You are not locked into one vendor's query dialect.
Auth and security built in
Sign-in and row-level security ship with it, so access control lives in the database instead of scattered across route handlers you can forget to guard.
Open source, no lock-in
Supabase is open source and self-hostable on standard Postgres, so moving off it later is a migration, not a ground-up rebuild.
Who uses Supabase
Supabase backs products that want Postgres and open source without running their own database infrastructure.
What we build on Supabase
Supabase is more than a database. We ship the whole backend on it, and we know where it fits and where it does not.
- SaaS on SupabaseThe full SaaS backend: Supabase Auth, Postgres, multitenant organizations and teams, and Stripe subscription or seat-based billing, wired together the way products actually ship.
- Multitenant with row-level securityTenant isolation enforced in the database with Postgres RLS, so one tenant cannot read another's rows even when a query is wrong.
- Auth, storage, realtime, edgeEmail, OAuth and SSO sign-in, file storage with access policies, realtime subscriptions, and edge functions for server-side logic. First-party pieces, not a stack glued by hand.
- Firebase to Supabase migrationA phased move that keeps the app online: schema and data ported to Postgres, Firebase security rules re-expressed as RLS, and auth migrated without password resets.
- Mobile on SupabaseReact Native, Expo, and Flutter apps on Supabase auth and realtime, with an engineered offline layer when the app has to work without a connection.
The Supabase stack we work in
From the Postgres schema up to the client, and the billing on top.
Security: RLS done right, not RLS forgotten
The most common Supabase data leak is a table shipped with row-level security switched off: because the anon key is public, anyone can then read the whole table through the auto-generated API. We treat RLS as the security boundary, and we make it fast.
RLS on by default
Every table holding user or tenant data ships with row-level security enabled and policies written, never left open behind a public API key.
Security, not filtering
RLS is the boundary; the query still filters explicitly. That pairing is also what keeps policies fast instead of re-checking every row.
No trusting client claims
Authorization checks a database table or server-controlled metadata, never a user-writable token field a client can quietly change.
Keys in their place
The service-role key that bypasses RLS never reaches the browser, and storage buckets get explicit policies rather than public-by-default access.
Supabase vs Firebase
Both give you auth, a database, storage, and realtime without running your own server. They differ where it matters for a product you intend to grow. Weighing the two in depth? Read the full Supabase vs Firebase comparison, or see our Firebase development work.

Questions
Is Supabase better than Firebase?
It depends on the product. Supabase is a relational Postgres database with full SQL, row-level security, and no vendor lock-in, which suits SaaS and apps you will grow. Firebase is a mature document (NoSQL) platform excellent for fast prototypes and simple data. We help you pick, and migrate between them when a product outgrows its first choice.
How does Supabase keep data secure?
Through Postgres row-level security. RLS is opt-in, so the real risk is a table left with it switched off, which exposes the whole table through the public API key. We enable RLS on every table with user or tenant data, write explicit policies, keep the service-role key off the client, and never trust user-writable token fields for authorization.
Can you build a multitenant SaaS on Supabase?
Yes. We model tenants with an organization and membership schema and enforce isolation with RLS at the database, so one tenant cannot read another's rows even if a query is wrong. Auth, per-seat or subscription billing with Stripe, and role-based access sit on top.
Can you migrate our app from Firebase to Supabase?
Yes, in phases that keep the app online. We port schema and data from Firestore to Postgres, re-express Firebase security rules as RLS policies, and migrate auth without forcing every user to reset a password. You get a plan before anything moves.
Does Supabase work for mobile apps?
Yes, for React Native, Expo, and Flutter, using Supabase auth and realtime. Supabase ships no built-in offline mode, so when an app has to work without a connection we add an engineered offline layer with local storage and a sync engine.
Is Supabase production-ready and does it scale?
Yes, with engineering. It is Postgres, so it scales the way Postgres does: indexing, query design, and connection pooling matter, and realtime has real limits you plan around. We build with those limits in mind instead of discovering them in production.
