Comparing Prototyping Tools For UX Designers

Let's take a look at three great tools: InVision, Atomic and Project Comet

As a UX designer my typical workflow can involve using 3-4 different applications for one design. One for mockups, one for prototyping/team collaboration and sometimes one for animation. I use both desktop and browser-based applications to get the quality, realistic prototypes I want. This process can prove to be tedious, especially when iterating screens or collaborating with a large team.


InVision is at the forefront of team collaboration. Theirs is a web-based application with a promise to be free forever. They offer realistic prototyping and in-screen commenting options.

However, screens must be built in another application which can slow the design process down. When designers are working with sometimes hundreds of screens it can be a pain to keep going back and forth between the original app to iterate your designs and InVision to add your transitions and share screens with your team.

Be on the lookout for their new Motion feature which promises to add “advanced animations for web and mobile design.”


Atomic is a browser-based application that only launched its beta back in 2014. Theirs is an all-in-one design and prototyping tool. With advanced animation capabilities it allows for one single flow from initial design straight through to realistic clickable mockups.

A great feature with Atomic is their advanced version control. You can scrub through your design changes with the history slider and see your work transform before your eyes. Atomic is code-friendly, with the ability to make css changes within the app for extra customization.

Project Comet

Adobe has announced their newest CC project set to launch in early 2016. Project Comet could be what native Creative Cloud users have been looking for; an all-in-one design, prototyping, collaborative tool.

The app has two main functionalities – design mode and prototyping mode. You can iterate your designs and see them update live in the prototype. They’ve also added in some time saving features like Repeat Grid that will have UX designers in high spirits. The app will be part of the Adobe CC family and can sync effortlessly with your other CC applications – this may prove to be the defining feature for many designers.
