#Supabase

Add authentication to Next.js with Supabase Auth - client setup, sign-up/sign-in, server-side sessions with SSR, and RLS - plus when owning your auth is the better call.

Neon vs Supabase - serverless Postgres with branching vs a Postgres-based backend-as-a-service - with a decision table and a clear verdict for your stack.

Supabase vs Firebase in 2026 - SQL vs NoSQL, auth, realtime, pricing, and lock-in, with a clear "choose X if" verdict for your next app.

Use Supabase with Next.js the production way - browser/server clients, server-side sessions, and querying - plus when to add Prisma on the same Postgres.
