UI kits typically have two primary use cases:

1. For rapid prototyping 

2. For the final product design 

The pre-made UI kits, like the ones featured on our list, are particularly useful for rapid prototyping. The elements can be used to quickly mock up pages or screens, take an idea, and make it a reality. These designs can then be used for version control, feature idea pitches, in closed feedback groups, and in the early stages of product development. 

Using customizable kits can be a time-saving way of developing the final product, although some teams prefer creating their own UI elements during this stage for more flexibility. 

Regardless of whether you’re opting for a pre-existing version or building your own from scratch, UI kits are so versatile that they can be used at any stage of the product development process. 

That being said, there are certain areas that really benefit from UI kits, especially if you’re looking to improve customer experience. For example, illustration-based UI kits are a great way to add personality to web pages. Or, you can use them to showcase different use cases for your product. Customizable illustrations can also be a good way to ensure brand alignment.

Similarly, icons and other customizable elements can be useful during product walkthroughs to draw attention to certain aspects. If you’re trying to explain complex steps, adding a visual element can make it easier for users to understand.

The great thing about UI kits, since many can be fully customized, is that there’s no way to tell you’ve used these handy design resources in the first place. As anyone who has tried to establish a brand identity will know, consistency is key. So, if you are opting to use UI kits to speed up your development process, then incorporating key branding elements is a must. 

A strong brand has an established style, whether that’s a minimalist aesthetic, bold color pops, distinctive fonts, layouts, or anything else, so you want to make sure you can customize the assets available in the kits. Incorporating brand colors is one of the easiest ways of ensuring consistency across your outputs. For kits with limited/fixed color options, pick neutral tones and add your brand colors to aspects you’re creating yourself. You’ll know your job is done when you have achieved a unique look.

With UI kits, your product teams can work smarter, not harder, to produce winning results and ensure a high-quality product experience. UI kits’ pre-made nature means you spend less time in development while still putting out high-quality products, and if the need arises, you are equipped to respond to issues quickly.

Think of these scenarios: 

• A landing page not converting? Make the edits using a dedicated UI kit and get it back up and running before anyone notices. 

• Experiencing negative feedback for your mobile app? Update the interface with UI kits compatible with iOS and/or Android. 

• Data not displaying correctly? Chart UI kits can provide you with templates to build on and improve the look and feel of your dashboards.

You get the idea. 

UI kits are also useful for improving your product experience even before you launch to market. New ideas can be materialized and tested using high-res wireframes, mockups, and prototypes enabling you to gain feedback on a product that’s as close to the real thing as possible.

UI kits make a great addition to any product design team’s workflow. Whether you’re trying to speed up development, maintain style consistency across the product, or just create a more engaging, user-friendly product, these kits can help you achieve it. With plenty of high-quality, free design resources available online, you can spend your development budget on areas that really need it.
