10 Best Prototyping Tools For UI/UX Designers — How To Choose The Right One?

One of the most popular phrases in the world of design from IDEO states that " If a picture is worth a thousand words, a prototype is worth a 1000 meetings". Whether it is plain experimenting or turning your vision into something tangible, prototypes (low, medium or high fidelity) assist in testing and building while preserving overall design consistency.

As designers are bound to design things that are described to them by clients, not all actually understand what the requirements really are. This is then followed by a series of meetings, emails or phone conversations to reach their final design which truly is a hassle. All these problems can be circumvented by using prototyping tools.

Prototyping tools allow designers and clients to collaborate better while being in the same context rather than having conflicting perspectives. The clients get a visual overview of what is actually going to be made. It helps teams to build understanding, to explore options and barriers that only become visible when you build and test something. At the end of the day, prototyping tools become a platform for full creativity and experimentation for the product team.

The biggest benefit of prototyping tools is the risk, the sooner we fail, the faster we would learn. When you fail with your mockup, you land softly — there's always the chance to validate things that work, iterate and improve. Else, once we start sailing on a boat in the wrong co-ordinates, we will never reach the shore.

How we use Prototyping tools?

We believe driving customer engagement through user experience is important. Preparing mockups or wireframes of an app consumes a lot of time for our designers and also creates a lot of back and forth with the clients which could possibly harm our relationship with our clients.

We at Maruti Techlabs are using prototyping tools to get rid of the hundreds of problems associated with designing. It helps our designers bring their ideas to life and in doing so we are able to provide interactive prototypes to our clients. We show the concepts in action and help them see how their ideas will take shape.

Since user experience is a powerful metric for branding we often use prototyping tools to show our clients different iterations of the product mockup that they requested. It allows our UI/UX designers to produce a 'Proof of Concept' which could be a key factor in the commercial relationship between developers and their clients.

How to choose the right prototyping tool?

Choosing the right tool is the key to describing your thoughts and collaborating better with your clients. With the abundance of so many online prototyping tools, choosing the right one is not an easy task. Every tool is different from each other as it lacks or has a new feature to stand out from the rest.

In order to choose the right prototyping tool for designing, there are a few factors which need to be evaluated for that tool to check whether it fits our needs or not.

1. Learning Curve:

Firstly, we have to analyze how easy is the tool to adopt. Let's call it the learning curve i.e., how long it takes for a designer get a hold of the tool. Since all tools are different from each other and provide various features, it would consume a lot of time for the designer to learn the tool.

2. Sharing:

As collaboration is key for design, we check how well suitable it is for teamwork. The tool should provide collaboration ability for multiple people to be in sync with each other. Since every designer has their own perspective/ ideas for a project it's imperative that all of them stay on the same page.

3. Usage:

Another point to consider when choosing a prototyping tool is how well it fits your design process and other tools you regularly use. For example, if you are designing in Photoshop, Illustrator or Sketch, it would be great if your prototyping software could directly use the files produced by these apps without requiring you to export assets separately and then build everything from scratch to create the interactions.

4. Ease of use and comfort:

The ease of use in using the prototyping tool is essential for the designer to save time and help increase output. It should reduce the number of steps required for a designer to complete a task rather than increasing it.

5. Cost:

There are many prototyping tools out there, many of which with niche features. But there is a catch with these tools, that they do not fit our budget. And hence, we should be careful while choosing tools and not be blinded by the features.

6. Fidelity:

What would be the requirement for the prototype? Whether you just require a mockup of the app layout or do you need something that supports more details and complex interactions? There can be different requirements for projects which could be classified into low, medium and high fidelity. Low fidelity would mean where we just want to test the idea. On the other hand, Medium fidelity would be when we're focusing on layout, information and interaction design. And finally, High fidelity when the most important things are visual design, animation, and micro-interactions.

We'll end the list with another powerful prototyping tool called "Balsamiq Mockups". It replicates the speed and convenience of creating mockups on paper, but on a digital medium. Designers can choose from more than 500 pre — made icons and items — or components they draw themselves. The interactions are basic, and the final, low-fidelity prototype feels more like an interactive, high-fidelity wireframe.

If you are a 'UX newbie', this tool works wonders as it is highly straightforward to use. Balsamiq's sweet spot is the UX ideation phase. It produces really great rough sketches of the prototype for clients to view, which is a big plus for brainstorming sessions. Adopting really simple and fast keyboard shortcuts for users to increase productivity and the speed of creating mockups. With all of its low fidelity features, we can consider it more as a wireframing tool rather than a prototyping tool. If you are not a professional designer and you are looking for a tool that allows creating simple and static wireframes, Balsamiq can be used.

In conclusion, these prototyping tools have their own special advantages, specialties and suit different needs. Admittedly, we have not included a lot of other prototyping tools for UI/UX designers. There are lots of other tools out there, most of which have the same features as mentioned in the above prototyping tools. Some honorable mentions are Moqups, UXPin, Prototype on Paper, Proto.io, and Flinto which have some unique features and ease of use as compared to the above.

Ultimately, it all comes down to choosing the one that works best for you. If you are a seasoned designer working on complex animations, Principle might work best. Or, if you are a design newbie, then Balsamiq Mockups should be your go-to.

We come from a time where mockups were made in paper and show to the clients, and now with this leap in technology we are capable of doing so much more. Going beyond the boundaries of technology, down the line, we can expect to see more innovations and enhancements not just in the UX prototyping segment, but in the design industry collectively.
