# Understand what a website clone includes

> Understand the difference between a rendered website export and a working application, including JavaScript, forms, login, databases and backend code.

A browser export can capture frontend material it receives. It cannot recover private server source or a database. Rebuilding a working application requires more than saving its appearance.

## Separate the page from the application behind it

A browser receives documents, styles, scripts and responses needed to display a page. A server may generate those responses using application code and a database that are never sent to the browser. Saving the visible result does not turn it back into the original server project.

For example, a product card may show a name, image and price. The rendered card does not reveal the inventory database, payment integration or administrative controls that produced it. If you own the site and need a complete migration, obtain the source repository, content export and backend configuration through your existing hosting or development workflow.

## Why copied buttons can look right but do nothing

A button’s markup and CSS describe part of its presentation. JavaScript can attach event listeners separately, delegate events from a parent, or update the element through a framework. Those connections are not equivalent to the button’s HTML. Copying a visible element does not guarantee that the code controlling its behavior is included.

Even when browser-delivered scripts are available, they may depend on build-specific modules, page initialization, application state or remote services. An export that resembles the original screen can therefore have a menu that never opens or a form that never submits. Treat working behavior as something to verify explicitly.

## Inventory the behavior you actually need

Before rebuilding, list the important actions and their expected results. For a brochure site, working navigation and a contact form may be enough. For a dashboard, you may need authenticated data, filters, permissions and saved changes. These are different implementation tasks even when the initial screenshot looks simple.

Use your own application’s services and account flows. Replace navigation destinations and remove references to endpoints that belong to the source site. Do not treat an empty success message as proof that data was saved; confirm the expected result in the system that owns the data.

Example: rebuild-behavior-checklist.md

```
# Rebuild behavior checklist

- Navigation: each destination exists in this project.
- Menu: opens, closes and supports keyboard focus.
- Form: validates input and calls our own handler.
- Submission: shows loading, success and failure states.
- Data: comes from the intended application source.
- Account controls: use our existing authentication flow.
- Assets: resolve without depending on a preview session.

Record each item as implemented, intentionally omitted, or unresolved.
Do not mark a visual placeholder as a working feature.
```

## Use a frontend export as a reconstruction reference

Sitepeel’s Clone page tool is useful for studying a rendered layout and taking frontend material into your project. Review the export at the captured viewport, identify the sections you need and rebuild them using your own components. Keep the content hierarchy and useful layout relationships while removing unnecessary page-specific structure.

If an AI assistant is helping, state that the export is a frontend reference. Provide the behavior checklist alongside it and identify the stack it should use. Ask it to list unresolved integrations before presenting the result as complete. This prevents a visually convincing placeholder from being confused with a working migration.

## Verify the rebuild beyond the first screen

Open the rebuild through your development server and walk through its important paths. Try a narrow viewport, a direct visit to an inner page, a failed request and a page refresh. Inspect the browser console and network panel when an action behaves differently from the original.

If your objective is a full migration of a site you own, a source-level migration is often the clearer route. If your objective is to learn from or reuse a permitted frontend layout, a browser export can be enough. Decide which outcome you need before choosing how much of the application to rebuild.
