Prototype in your product, not in mockups

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

Connect your repo and start turning product ideas into real, testable changes.
