UI Kits vs. Design Systems

9 Nov 2023

We bet you've heard it before: creating a killer UI design isn't just about eye candy—it's about weaving an intuitive user experience (UX) that gracefully guides users on their digital journey. Picture consistency as the secret sauce, seamlessly tying together every click and scroll.

Among the myriad of methods designers use to keep designs consistent, UI kits and design systems steal the spotlight. While marching towards the same goal, they each play a unique and crucial role in different chapters of the product design process.

Get ready for your crash course on deciphering UI kits and design systems—how they differ, the magic they bring to the table, and the perfect moments to unleash their powers in your design journey. Consider this your trusty guide, helping you navigate the fascinating terrain where UI design, UX, UI kits, and design systems converge.

What is a UI Kit?

UI Kits are specialized design toolkits containing pre-made components, elements, and templates tailored for specific devices or platforms. They're like a designer's ready-made arsenal, with device-specific building blocks like buttons and icons. The purpose? To give designers a jumpstart by offering elements optimized for a particular environment, ensuring visual harmony and device-specific user experience consistency. Simply put, UI Kits are your handy toolbox, customized for smoother design journeys on specific devices or platforms.

Advantages of Using UI Kits

  1. Speedy Design: UI Kits are the express lane to a polished design. Designers can breeze through the initial phases with pre-designed elements, saving time and effort.
  2. Consistency at your Fingertips: Ensuring a consistent look and feel becomes a piece of cake. UI Kits offer a unified design language, making maintaining a cohesive user experience easy.
  3. User-Friendly Iteration: Want to try out different looks without starting from scratch? UI Kits allow for quick iterations, helping designers experiment and fine-tune easily.
  4. Collaboration Booster: Collaboration becomes smoother when the whole team works from the same UI Kit. It's like everyone speaking the same design language, reducing confusion and ensuring everyone's on the same page.

Limitations and Considerations

  1. Risk of Generic Design: Since UI Kits provide pre-made elements, there's a risk of the design looking too generic. Customization is key to avoiding the "one-size-fits-all" appearance.
  2. Potential Overreliance: Relying too heavily on UI Kits might limit creativity. Designers should use them as a tool, not a crutch, to ensure the uniqueness of each project.
  3. Not Always Tailor-Made: While great for many projects, UI Kits might not perfectly align with the specific needs of every project. Customization is crucial to address the unique requirements of each design endeavor.

What is a Design System?

Design Systems are like the composers of a project, bringing together guidelines, rules, and reusable pieces to keep everything looking and working the same way. Picture them as the project's instruction manual, explaining how everything should look and behave. The main ingredients? A style guide that shows how things should look, standard elements everyone uses, and a set of rules for the user experience. So, Design Systems are the composers that make sure everything in your project works and looks great together.

Advantages of Implementing Design Systems

  1. Consistency Amplified: Design Systems act as the guardian of visual uniformity, ensuring every nook and cranny of your project follows the same aesthetic rules.
  2. Efficiency Overdrive: With reusable elements, designing becomes a breeze, cutting down time and effort on doing the same things over and over again
  3. Streamlined Collaboration: A common design language means everyone, from designers to developers, reads from the same script, fostering seamless collaboration.
  4. Future-Proof Flexibility: Design Systems pave the way for scalability and adaptability, making evolving and expanding your project easier.

Challenges and How to Overcome Them

  1. Resistance to Change: Introducing a design system can face resistance. The key is communication—helping the team understand the long-term benefits and involving them in the process.
  2. Maintenance Pains: Keeping a design system updated requires effort. Regular audits, clear documentation, and designated maintainers help overcome this hurdle.
  3. Flexibility vs. Rigidity: Striking the right balance between a flexible system and a rigid framework is crucial. Regular feedback loops and iteration can fine-tune this balance over time.

UI Kits vs. Design Systems: A Feature Breakdown

Navigating the landscape of UI design tools involves understanding the distinct roles of UI Kits and Design Systems. Think of it as comparing tools in a toolkit—each serves a purpose, but knowing when to use it is key. Let's dive into the specifics to demystify the features of UI Kits and Design Systems.

Key Differences Between UI Kits and Design Systems

Navigating the landscape of UI design tools involves understanding the distinct roles of UI Kits and Design Systems. Choosing between UI Kits and Design Systems isn't random; it's a nuanced decision-making process influenced by several key factors. Consider it a strategic decision-making journey where each factor is a compass pointing toward your project's most suitable design solution. In this section, we'll unravel the intricacies of these considerations, helping you decipher when to opt for UI Kits and when to lean toward Design Systems.


UI Kits: These are your design toolkits for specific tasks. They excel in providing a ready-to-go set of visual elements—buttons, icons, and the like. Think of UI Kits as your go-to when you need specific elements to swiftly enhance the look and feel of your project.

Design Systems: Taking a broader view, Design Systems cover the visuals and underlying principles. They include guidelines and an overarching design philosophy, ensuring a consistent and cohesive user experience. It's not just about the buttons but the entire coordination of design elements.


UI Kits: Quick and convenient, UI Kits allow for easy customization. However, there's a caveat—you risk the danger of ending up with a design that looks a bit too generic. The trade-off here is between speed and uniqueness.

Design Systems: Picture Design Systems as offering a more extensive toolkit. Yes, you can customize, but within a broader framework. This balance maintains consistency across the project while allowing room for tailoring elements to meet specific needs.


UI Kits: UI Kits are your go-to champions for smaller projects or when speed is the name of the game. Whether you're whipping up a quick prototype or giving a presentation a dash of flair, UI Kits are the trusty allies that do the job in a flash.

Design Systems: Entering the realm of larger projects, Design Systems take the spotlight, especially when scalability and enduring consistency are non-negotiable. They aren't just a choice; they're the strategic foundation for projects built for the long haul, not just a quick sprint.
