v0 is no longer just a polished screen
As v0 moves into full-stack apps, database integrations, APIs, and Vercel deployment, the risk changes too. A generated dashboard can become a real product before the team notices that customer data, subscription flows, and admin routes already exist.
The interface is not the security boundary. The boundary is server code, database, storage, webhooks, cookies, sessions, and access rules.
Minimum review for a v0 app
- Schema with explicit owner by tenant, organization, or user.
- Server-side queries filtered by owner.
- Server Actions validating session, role, and input.
- Environment variables kept outside the client.
- Stripe webhook with signature verification and idempotency.
- Private uploads with ownership checked before download.
- Preview separated from production and rollback tested.
The useful hype
v0, Vercel Marketplace, and serverless databases make the distance from idea to app much shorter. For founders, that lowers validation cost. For security, it raises the chance that generated code reaches production before the authorization, LGPD, and billing conversation happens.
Ask this before traffic
If the app has login, Stripe, customer-scoped data, admin panels, uploads, or AI connected to tools, it already moved beyond "just a prototype." Start with Promptbook and move to Risk Review when the signal touches revenue or customer data.

An AI-generated full-stack app should be treated as a product as soon as it touches databases, sessions, payments, or customer data.
