ProtoPie
FreemiumHigh-fidelity prototyping for complex interactions and multi-device flows
🖱️PrototypingAbout ProtoPie
ProtoPie handles the interactive complexity that Figma's prototyping can't — conditional logic, variables, formulas, sensors, and IoT device interactions. A ProtoPie prototype can simulate a real app almost perfectly: form validation, scroll animations, gesture recognition, and multi-step conditional flows. The Studio is a native Mac/Windows app. Connect feature integrates with external APIs for data-driven prototypes. Pricing: $13-29/month. Compare to Figma prototyping (simpler, less powerful), Principle (motion-focused). Best for: senior UX designers and teams prototyping complex interaction states that require conditional logic.
What's Great
- ✓Conditional logic and variables for realistic app simulation
- ✓Gesture, sensor, and multi-device interaction support
- ✓Connect feature for API-integrated data prototypes
- ✓Best-in-class for complex micro-interaction prototyping
Watch Out For
- !$13-29/month is significant for a prototyping-only tool
- !Steeper learning curve than Figma prototyping
- !Not designed for simple click-through prototypes
Common Use Cases
A UX designer prototypes a form that validates input, shows errors conditionally, and progresses through steps
A design team creates a data visualization prototype with real API data
