# Prototype in your product, not in mockups

Create and explore new product experiences directly in your application using real components, states, and constraints.

### Prototype directly in the product

Build and adjust new flows, layouts, and interactions inside your actual product instead of relying on static mockups.

### See how designs behave before they’re built

Work with real components, states, and logic, so what you design reflects how it will actually function once shipped.

# Fei Studio empowers the whole team

Including Product Managers, Designers & Engineers

## Use cases

### Validate Product Ideas

Turn early ideas into production-ready changes, release them behind feature flags, and learn from real user behavior before committing fully.

### Prototype With Real Code

Designers prototype new experiences directly in the product environment instead of relying only on static mockups.

### Accelerate Feature Delivery

Move from product requests, screenshots, or tickets to production-aligned pull requests faster by reducing handoffs.

### Improve Existing Features

Refine existing product experiences and workflows without rebuilding them from scratch.

### Refactor Legacy Interfaces

Modernize legacy UI surfaces and migrate them toward current component standards while preserving the structure of the real codebase.

### Rapid Product Iteration

Explore multiple variations of product flows quickly inside the real product environment to accelerate discovery and refinement.

### Stakeholder Demos

Create realistic demos using the real product environment instead of static mockups for leadership or customer conversations.

### Design System Alignment

Generate product updates that reuse existing components and patterns to maintain consistency across the application.

### Turn Support Feedback Into Product Changes

Translate customer feedback, bug reports, and support tickets into concrete product improvements aligned with the codebase.

### Explore UX Improvements

Experiment with navigation, layout, and interaction improvements directly in the real product environment.

### Build Enterprise Customizations

Create tailored product experiences required for enterprise customers while keeping changes aligned with the existing architecture.

### Test Feature Variations

Generate alternative versions of product flows and interfaces to explore new directions before committing to implementation.
