The 45 Best UI/UX Design Tools for Designers in 2025

Prototyping tools act as a bridge that gap between the initial design and the finished product. It is a rough draft to identify what works and what doesn’t. It can help us solve design problems before writing even a single line of code. Today’s clients want to see interactive prototypes, which show the concepts in action and help them see how their ideas will take shape.

The possibility of promptly sharing different iterations of ideas with clients can accelerate the design process. This flexibility is more important when we consider various device formats we must now factor in.

I feel happy because designing with particular emphasis on intuitive user interaction and ergonomics is becoming a common practice for many app designers, web developers, web designers and programmers. Also, designers who design for products that goes far beyond displays.

At the same time, we will see the difference between wireframe, mockup and prototype before looking at the prototyping tool. The terms wireframe, mockup and prototype are often used interchangeably to mean the same thing. But, they are not the same.

Wireframe

A wireframe is a static, low fidelity representation of a design. If you want to design a web application or a mobile application, you will first need a sketch of how each page is going to look like. You can define the application flow and a first draft of design. It has a sketch of how it will look like, what buttons will be there, what fields will be there, etc . It is a visual illustration of a web page that showcases how each component of the web page is organized and how it will look like.

Mockup

Mockups are middle to high-fidelity, static, design representation. Mockup is a visual design draft, or even the actual visual design. They are static displays of how the visuals of the final product should look. Mockup represents the structure of information, visualises the content and demonstrates the basic functionalities in a static way. It encourages people to actually review the visual side of the project. This offers you the opportunity to make the vital decisions about color schemes, typography, and style.

Prototype

A prototype is middle to high-fidelity representation of your final design to almost any degree of detail you choose. It is a simulation of the final interaction between the user and the interface. It allow users to explore the UI, pinpointing which elements work best, and predicting usability problems before they become problems.

Prototypes provide a variety of functions in the web design process. Here I’ve compiled them into four main categories:

• Test logic — You want to see for yourself whether or not an idea will work as you planned.
• User testing — You want to fine-tune the product based on your target users’ preferences.
• Pitch an idea — You want to demonstrate how your idea works while presenting to clients.
• Proof of concept — You want to get the rest of your team on board with your suggestion.

Of the three, the one that would make the most of an impression would be the prototype. Each prototype tool has different end goals and audiences. However, the same prototyping tool does not work for every situation.

There are so many UI/UX prototyping tools out there how do you know which tool to choose? Choosing the perfect tool will bring you twice efficiency with half the effort. Ask yourself some questions before making your choice.

1. Learning: How long do I need to learn this tool? How long will it take me to create the prototype once the tool was up and running? Avoid heavy tools featuring an abundance of unnecessary whistles.

2. Fidelity: What is the reliability requirement of your prototypes? Do you need something that supports more details and complex interactions? Are wireframes that shows the app layout and structure sufficient?

3. Skills: Are you a newbie or professional in this filed? Do you have visual design experience? Is programming knowledge or coding required?

4. The purpose of the application: Are you prototyping mobile apps, desktop apps, websites, or all of the above?

5. Share: It is important to consider the collaboration features supported by the prototyping tools. You can ability to share your prototype with others and work collaboratively on the prototype.

6. Pricing: How much do you want to pay for design tools?

There are many tools available on the market for prototyping websites and mobile applications. Below I’ve compiled a list of the most popular ones that ease the process of conceptualizing, wireframing, prototyping, mockups and designing digital products. I hope you find out the one fit your exact need.

1. Sketch

Sketch is a power, flexibility, lightweight and easy-to-use package tool. It is a vector design tool entirely focused on user interface design. Vectors mean scalability. Its Vector shapes easily adapt to changing styles, sizes and layouts, which allows you to avoid a lot of painful hand-tweaking. Sketch is built for modern graphic designers that use a single unit, styles only relevant to UI design, a built-in iPhone previewing tool called Mirror and Artboards, the most efficient way to design multiple screens.

Designers can easily edit the position, rotation and size of one or more objects at a time. You can reuse the named Layer Style in on multiple objects. Sketch comes with unlimited gradient fills , different blending modes, infinite borders, shadows and more. This tool lets designers dynamically edit 4 different types of blur like Gaussian, Motion, Zoom, and Background. It is ideal for iOS design. You can export your layers with one click directly out of Sketch. No need to add separate slice layers.

Sketch is made specifically for Mac OS X users to design interfaces, websites and icons. Sketch is perfect for designing for multiple devices, and delivering assets is a breeze. It is the ultimate tool for iOS, Android and Web design.

22. Principle

Principle is ideal for prototyping intricate motion design explorations for mobile and desktop applications, which uses a timeline interface giving the designer the flexibility to express experiences using motion. It has a record feature that can export prototypes to a video or an animated GIF that can be shared on Dribbble, Twitter or anywhere. It allows users to create complex experiences in very short periods of time. Though you can create prototypes for web projects, the current focus of Principle is on mobile.

It uses artboards to animate elements between states, so as you work on your prototype, you can live-preview your designs on the top right-hand side window. Alternatively, you can mirror your designs on an iOS device. Prototypes are built using screens imported from Sketch or Photoshop. The imported elements are then manipulated within Principle to create a wide array of interactions.

Principle does not include a collaboration tool, this drawback will likely be overshadowed by its offline capabilities. However, the flexibility of working offline is further highlighted by increased speeds, since you’re not relying on a potentially unreliable or slow connection.
