How to Choose the Best Prototyping Tool?

As a developer, it is important for you to be very picky when it comes to selecting the tools you use for your work. The features and the options provided by the tool you use will have a lot of impact on the final results. The following are a few aspects that should be considered before you start using design prototyping tools. The following are some of the aspects-


One of the first things to check is the compatibility of the tool. The prototyping tool you select should not only be supported on your computer but should also be supported by other platforms. Tools like Wondershare Mockitt allow such functionality and users can use it through browsers or with their Mac or Windows computers.


Next up, make sure that the tool has all the features you want. Things like templates, customization, color correction, and the ability to integrate with other tools are some of the must-have features. This enhances the overall result significantly.

Level of Fidelity

Based on your requirement of the prototype, you need to select the tool that offers low, medium, or high fidelity. For basic testing and layout, you can go for tools with low and medium fidelity but for more complex details like adding animation, micro-interactions, and visual design, you should consider the tools with high fidelity.

Ease of Use

The tool should be such that allows the design to complete the task in minimum steps saving time. A well laid out tool has an interactive interface and makes the task easy.
