Create from clickable prototypes to fully-functional simulations, without typing a single line of code. We provide a full range of tools, so that you can focus on creating delightful user experiences. Testing through simulations will reduce rework and boost user adoption.
Design your UI assets for free, without any restrictions on number of projects. Enjoy all UI design features, from the vector design tool, the pen tool, to pathfinders and more.
Create prototypes for websites and web apps that adapt to multiple screen resolutions for desktop and mobile. The UI elements in your screens will also adapt automatically. One free prototyping tool to rule all devices!
Visualize your web and mobile prototypes, while you design them. Simulate prototype behavior while you design. Use our Emulator and Viewer App to test your prototype live on any iPhone, iPad or Android device.
A prototype is a preliminary version or model of a product, system, or feature that is created to test and validate design ideas, interactions, and functionality before proceeding to full-scale development.
Prototypes serve several important purposes, including:
There are various types of prototypes used in the design process, including:
There are several tools available for creating prototypes, depending on the level of fidelity and interactivity required. Some commonly used tools include:
The choice of fidelity for a prototype depends on the goals, stage of the design process, and the specific requirements of the project. Low-fidelity prototypes are effective in the early stages to explore and communicate design concepts quickly, while high-fidelity prototypes are useful for testing detailed interactions and getting closer to the final product experience.
When conducting user testing with prototypes:
