Postgres with auth, storage, realtime, and an auto-generated API — all open source.

2026 verdict

Best all-in-one backend for new projects in 2026

Best for: New projects that want a full-featured backend without managing five separate services — especially apps that need auth, file storage, and realtime built in from day one

Not for: Projects that need maximum database performance tuning, enterprise compliance from day one, or teams already deeply invested in a different database provider

Overview

Supabase made a bet in 2020 that the market was tired of proprietary NoSQL databases and Firebase lock-in. That bet paid off. In 2026 it is one of the fastest-growing developer tools companies in the world, and the go-to backend for new projects that want comprehensive infrastructure without stitching together a dozen services.

The foundation is just Postgres. There is no proprietary query language, no special SDK required. You can use any Postgres-compatible ORM — Drizzle, Prisma, SQLAlchemy, ActiveRecord — and standard pg clients. Real Postgres means pgvector for embeddings, pg_cron for scheduled tasks, and every ecosystem extension works.

On top of Postgres, Supabase auto-generates a REST API from your schema using PostgREST. Every table gets CRUD endpoints automatically. Row Level Security policies written in SQL control what each authenticated user can read and write — no custom authorization middleware required. The JavaScript SDK handles these policies transparently, enabling your frontend to query the database directly without a bespoke API layer for most use cases.

The auth system handles email/password, magic links, phone OTP, and OAuth with 20+ providers out of the box. The Realtime engine uses Postgres logical replication to stream database changes to connected clients — useful for live dashboards, collaborative editing, and multiplayer features. Storage manages file uploads with image transformations, CDN delivery, and access policies that mirror your row-level security rules.

Edge Functions based on Deno run globally and integrate tightly with the rest of the stack. The free tier is production-capable for small apps, though projects pause after one week of inactivity.

Pros and cons

Pros

+Real Postgres — every ORM, migration tool, and SQL client works
+Auto-generated REST and GraphQL APIs from your schema
+Row Level Security enables secure direct database access from the frontend
+Auth, storage, realtime, and edge functions all included
+Open source and self-hostable — no permanent vendor lock-in
+pgvector support makes it excellent for AI-powered apps

Cons

−Free projects pause after 1 week of inactivity
−Edge Functions are less mature than AWS Lambda for complex use cases
−Migration tooling is less mature than raw Postgres setups with Flyway or Liquibase
