# Platform Overview

> The services that power your product — set them up at your own pace

Your apps look great on the surface, but underneath they're powered by a shared platform. This is where you set up auth, storage, AI, credits, email, and everything else your product needs.

<Tip>
  You don't need to set up everything at once. Start with auth + database + one AI provider (that's the [Quick Setup](/setup/introduction)), then add more services as you need them.
</Tip>

## What to set up first

These are the essentials — most apps need them.

## Add when you need them

These are powerful but optional — add them when your product is ready.
