Top Recommended Replacements
Rive
FREEBest for Interactive Animation
Why we like it
Uses 'State Machines' to build logic-driven animations that respond to real-time inputs; tiny file sizes (JSON-based); production-ready code output; works across web, mobile, and games.
Keep in mind
Requires a different mental model (logic nodes) compared to ProtoPie’s layer-based triggers; no native support for phone sensors like the accelerometer.
UXPin
Best for 'True' Code-Based Logic
Why we like it
Prototypes behave like real apps because they use real code components; supports variables, conditional logic, and API calls; excellent for design system management.
Keep in mind
The 'Merge' technology (syncing React components) requires technical setup; less focused on mobile-first gesture animations.
Origami Studio
FREEBest Free Advanced Tool
Why we like it
100% free (by Meta); highest level of performance for mobile gestures; uses 'Patches' for complex logic; allows access to hardware sensors (camera, GPS).
Keep in mind
Mac only; very high learning curve (node-based programming); no built-in design tools (must import from Figma/Sketch).
Justinmind
FREEBest All-in-One Desktop Tool
Why we like it
Works 100% offline; excellent support for data-driven prototypes (real data lists and forms); includes 2,000+ UI components out of the box.
Keep in mind
The UI can feel dated; the web preview can occasionally lag compared to native device testing.
Proto.io
Best for Rapid Realistic Sims
Why we like it
Vast library of animated assets and icons; fully web-based; easy-to-use timeline for complex multi-layer animations; allows for user testing with video recording.
Keep in mind
No 'forever free' plan; subscription is quite high for individuals; limited hardware sensor support compared to ProtoPie.
Framer
FREEBest for Web Prototypes
Why we like it
World-class 'Magic Motion' for smooth transitions; prototypes are essentially real websites; can be published as a live site instantly.
Keep in mind
Pivoted almost entirely to web-building; has lost many of its mobile-app-specific testing features (like native sensor access).
Drama
Best for Mac Animation Purists
Why we like it
Combines design, animation, and prototyping in one app; features a unique 'Magic Move' that is smarter than Figma's; very lightweight and fast.
Keep in mind
Mac only; smaller community ecosystem; lacks the advanced logic (variables/conditions) found in ProtoPie or UXPin.
Uizard
FREEBest AI-Powered Prototyping
Why we like it
Turns hand-drawn sketches or screenshots into editable prototypes instantly; perfect for rapid validation; best for non-designers.
Keep in mind
Very low creative control; high-fidelity logic is basic compared to professional tools.
Principle
Best for Micro-interactions
Why we like it
The most intuitive timeline-based UI animation tool; native Mac performance; excellent for 'Dribbble-style' motion showcases.
Keep in mind
No support for logic, variables, or hardware sensors; Mac only.
Penpot
FREEBest Open-Source Freedom
Why we like it
100% free; uses real CSS Flexbox/Grid logic for handoff; self-hostable; perfect for teams that value data sovereignty.
Keep in mind
Prototyping features are currently mid-fidelity; lacks the advanced interaction depth of ProtoPie.
