How to Vibe Code an App From First Screen to Production

Turn the idea into an application map

Write down who uses the app and what each role can create, read, update, or delete. Then map the smallest set of screens needed for one valuable outcome.

Define the core data entities in plain language. If the app manages projects, specify what a project contains, who owns it, who can join it, and what should happen when it is archived.

• User roles and permissions
• Core screens and navigation
• Data entities and relationships
• External services and webhooks
• Success and failure states

Build vertically instead of screen by screen

A vertical slice completes one workflow through the interface, server logic, database, and confirmation state. This exposes architecture problems earlier than generating ten disconnected screens.

For example, build project creation all the way through authorization, validation, persistence, and display before creating project settings, invitations, reporting, or billing.

• One real action beats several static mockups.
• Data validation belongs on the server as well as the form.
• Permissions should be enforced where data is accessed, not only hidden in the interface.

Prepare for the second month, not just launch day

Decide how errors are captured, backups are restored, dependencies are updated, and user feedback becomes scoped changes. Document environment variables and deployment steps while the project is still understandable.

A maintainable app has predictable structure and a clean handoff path. If every change requires re-prompting the entire system, the architecture needs simplification.
