When comparing Keynote vs ProtoPie, the Slant community recommends ProtoPie for most people. In the question“What are the best mockup and wireframing tools for websites?” ProtoPie is ranked 20th while Keynote is ranked 24th. The most important reason people chose ProtoPie is:
As the interface is very clean and simple, it enables you to create interactions by combining objects, triggers and responses just like that. No need for wireframing or shitty mockups, just get to hi-fi prototyping right away.

Ranked in these QuestionsQuestion Ranking
Pros
Pro Imports nearly every type of asset
Can import all kinds of assets (images, videos, PDFs, sounds) into mockup without hassle.
Pro Animations and transitions
Keynote currently is one of the very few tools that supports animation of elements and transition of views without programming.
Pro Text Styles makes it easy to create typography systems
Pro Smart Snaps
Keynote has alignment grids (aka snap to grid feature) that snaps to end, midpoints, baselines etc of objects and grids. They are super useful when you want to follow a structured layout for your wireframe.
Pro Smooth and gradual learning curve
As the interface is very clean and simple, it enables you to create interactions by combining objects, triggers and responses just like that. No need for wireframing or shitty mockups, just get to hi-fi prototyping right away.
Pro Native prototyping
Deploy prototypes on any device right away. What's the point of prototyping mobile apps if you cannot deploy it on your mobile devices easily?
Pro IoT, Interactions across devices
Create prototypes e.g. chat platforms, payment apps etc. and deploy them on multiple devices and have them communicate with each other.
Pro Utilizes sensors very easily
Easily control the sensors of smart devices in your prototype, such as tilt, sound, compass, proximity sensor, vibration motor and 3D Touch sensors.
Pro Runs on Mac and Windows
It offers the same features on both MacOS and Windows. Plus, you can switch machines as long as you are logged in to ProtoPie Studio.
Pro Fast and easy sharing
Sharing is very easy via the cloud. Open the prototype in desktop or mobile browser, or deploy the prototype on the ProtoPie Player app. All is possible.
Pro Code Free
No coding needed to do interactions for your prototypes. You just choose the objects and link them with the triggers and responses you want to based on your preferred interactions.
