Pros
Pro Completely free
Origami is offered to the public completely free, no monthly plans, no upfront cost whatsoever.
Pro Powerful animations and interactions
Origami was actually built to help Facebook designers work on Paper, one of Facebook's latest apps. Every animation that is coded into Origami was first made for Paper. It uses powerful 3D effects and some of the most advanced features for scrolling, tapping and swiping to create a faithful and interactive prototype.
Pro Native testing
Developers can develop their prototypes with origami through their desktops, but the testing itself is done on the native devices.
Pro No code required
Origami is built by designers for designers. As such, it allows for quick prototyping without writing a single line of code.
Pro Open source
Origami is free and open source and it is hosted on GitHub.
Pro Like only-Mac-integration! Great app! Thank you.

Pro Use external data
You can use REST API to get data to your prototype.

Pro Free

Pro Cross-platform
It is a Chrome app and you can test prototypes on any device that supports WebGL or Canvas.

Pro Prototype two-device (master — companion) apps
You can setup communication between two devices.

Pro Components
You can build one interactive component and then reuse it with different input values (like images, txt, width, speed — any value you can imagine).
Cons
Con Steep learning curve
Origami is a toolkit for Quartz Composer, and unfortunately the learning curve for it is quite steep. Especially for beginners.
Con Mac only
Since Origami is not an app in and on itself, but a plugin for Quartz Composer, which is built by Apple. Therefore, Origami is only available for Mac and for a developer to download and use it, they need to register as an Apple Developer.
Con Mouse driven interactions
There's no way to directly test the tactile interface.
