Frontend Visual Editor

A visual editor concept for websites and mobile app interfaces. Edit frontend designs with live preview and comprehensive style controls without changing backend code.

Overview

This is a proof-of-concept tool that demonstrates a workflow for editing frontend designs visually while keeping backend logic completely separate and untouched.

The Workflow

1. Upload Website/App - Import your website or mobile app interface
2. Generate JSON - System creates a JSON representation of the frontend (backend remains unchanged)
3. Open Live Editor - Edit styles, colors, layouts, and spacing visually with real-time preview
4. Save JSON Changes - Export your modified design as JSON
5. Apply to Code - Upload the JSON changes back to your codebase
