Moqups vs ProtoPie

Moqups is built in HTML5 and standard Javascript, so it doesn't require any plugins to use. The application is very fast to use.

As well as a standard snap-to-grid, Moqups supports the 960 gridsystem.

The Free Plan offers 2 active projects with at most 300 stencils each and 5 MB of storage. This plan does not include: Master Pages, Real Time Collaboration, Privacy Settings, Unlimited Revisions, Unlimited Project Archiving and Teams.

Moqups has an extensive list of keyboard shortcuts. Simply type some A-Z letters to search for components. F1 for an overlay help screen.

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.

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?

Create prototypes e.g. chat platforms, payment apps etc. and deploy them on multiple devices and have them communicate with each other.

Easily control the sensors of smart devices in your prototype, such as tilt, sound, compass, proximity sensor, vibration motor and 3D Touch sensors.

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.

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.

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.
