How to choose the perfect Bootstrap UI Kit?

When choosing a Bootstrap UI Kit, you may want to keep the following points in mind. Depending on your use case, you can find a free UI Kit or a premium one with support.

1. Easy To Customize and Use

A bootstrap kit that is easy to customize and build upon is favorable as you would often want to override a few styles in your CSS. UI Kits that provide SCSS files along with an included build system on Gulp or any other build system should be preferred for this.

2. Full Documentation

While Bootstrap itself is well document, you would want the UI Kit built on top of it to also include it’s own documentation as these UI kits generally override many default styles of the Bootstrap. Further these UI Kits also include custom plugins like slider, tables, color picker, drag and drop UI etc, which need to be documented properly. You will find MDB UI Kit to have great documentation in this regard.

3. Pre-built Example Pages

Having pre-built example pages makes it easier to adopt the UI Kit in your own design. The more example pages and sections that are included, the better. This should range from dashboard, ecommerce, account, team, blog etc. thus giving you a wide range of option to build in future.

4. License for Business or enterprise

If you are using the UI Kit for business or enterprise then you would want to see the availability of an enterprise or business license as these will come with better support and more permissive use-case such as building a SASS product. Our top ranked UI Kits will fulfil these license needs.
