  1. 01
    Authentication

    Clerk

    Drop-in authentication and user management for modern apps.

    Why this: Drop-in auth that handles MFA, orgs and SSO without bespoke flows.

  2. 02
    Database + storage

    Supabase

    Open-source Firebase alternative with Postgres, auth, storage.

    Why this: Postgres-backed BaaS with EU regions; you'll outgrow the BaaS layer later but Postgres stays.

  3. 03
    Hosting

    Vercel

    Frontend hosting and serverless platform built for Next.js.

    Why this: Next.js on Vercel is the friction-less default; switch to Firebase App Hosting if you outgrow it.
