You don't code these layers — you learn when each one matters

The lesson, in plain language

Most first sites need no backend. A backend enters when users log in, private data is stored, forms save to a database, roles exist, uploads happen, or payments happen inside the site.

Seen in the demos: The Daily Bean demo does not take real payment because a purchase flow and customer data would raise the responsibility level.

Prompt lab

Explain when a simple site needs a backend, what Supabase RLS protects against, and why collecting personal data without protection is risky.

Decision card

The common failure: Adding login, database forms, or payments just because AI can generate them.

Tier-1 stays backend-light on purpose. Data safety is not a beginner shortcut.

Your task

Decide honestly whether your first site needs a backend right now.

Mistake detector

The usual trap here: Adding login, database forms, or payments just because AI can generate them. Tick only what you have genuinely done — anything unticked is where that trap usually starts.

0/4 confirmed — be honest, this checklist is for you, not for us.

Where this connects to your audit

Save your backend/data scope decision as project evidence before adding any risky forms, accounts, or payments.

The habit this builds

Don't ask AI for a finished website and stop there. Run the loop this module teaches: brief, generate, inspect, fix one thing, document what changed. That loop — not any single trick — is the skill Webnailed trains.
