5 Best Software Prototyping Design Tools for UX/UI Designers in 2018

Mar 3, 2018

What is software prototyping? Which tool is the first came into your mind when mentioned about software prototyping tool? Actually, nothing mysterious about software prototyping. It’s similar to the border term prototyping, a way for the manufacturer to get know what the final product will look like, so to evaluate how much additional resources could cost. On the other hand, superabundant prototyping tools are available nowadays, how to choose? Here I only pick the best 5 prototyping tools for your inspiration.

What is software prototyping actually?

Software prototyping is much the same as prototyping in the border product design field. It is a necessary step involved in daily software design. Normally, after doing enough UX research like gathering ideas, data, information, demands, evaluation, then it’s time to build a prototype.

The basic software stage including:

  • Idea Generation;
  • Demand Generation;
  • Function and Structure;
  • Prototyping Stage;
  • PRD (replaced by prototyping for most occasions);
  • Road Map

Usually, there are few common types of software prototyping:

1. Paper prototyping - this is mostly for self-usage, to record ideas;

2. Rapid prototyping - the most demanding prototypes, a wide range of application;

3. High-fidelity prototyping - emphasis interactions and user interface, for stockholders & development team;

4. Low-fidelity prototyping - emphasis interactions and thoughts, for design teams;

As you see, except paper prototyping, all the rest need to use a prototyping tool. For your better decisions, I will introduce the tool from several aspects:

Cost: How much will you spend?

Compatibility: Is the tool for Mac or Windows or both?

Key features: What can it do?

Learning Curve: How long it takes you to get started?

Usage pattern: Are you prototyping websites, mobile apps, desktop apps, or all of the above?

Speed: How quick can you finish the design on the prototyping tool?

Fidelity: What is the requirement of the fidelity of your prototype? Wireframes or low-fidelity or high-fidelity?

Sharing: Collaboration is key when it comes to design. A must consideration.

User’s feedback: See what others say.

Okay, here we go.

The above are the 5 software prototyping tools. Each has their unique features and some cons. But in general, they are a good a tool for prototyping design. As for me, I currently use Mockplus. I get design inspiration from their patterns, and it has various ways of presentation and share, shortest learning curve, flexible interaction and animation, and plenty more easy-to-use settings. All are good to me.
