The Top UI as a Service Businesses of 2025

User interface (UI) design is what designers create to let users interact with your products on a website or application. Before developers can bring your design to life, a UI designer produces these designs and works alongside developers or develops them themselves. However, UI design is expensive nowadays. And if you’re looking for a much more affordable alternative, a UI as a service model can be the answer to your UI woes. Here’s what you need to know about UI as a service!

What Are the Main Elements of UI Design?

• Buttons
• Dropdowns
• Checkboxes
• Icons
• Text fields
• Toggles
• Menus
