Prototyping is an essential part of any digital design process. It helps us simulate our designs, explore different user experiences, and test out journeys and user flows within our projects.

Prototyping isn’t so hard, especially if you follow best practices and toolset adjusted to your skills.

Prototyping tools can help create a website or app with little cost and relative ease — from a rough design idea to a finished product.

There are plenty of web design tools around, but prototyping tools have come into their own in recent years. With these prototyping tools, you’ll be set to meet any design challenges you might face, whether you want to create something beautiful or technical from an idea. With any prototype, it’s important to test and play with your interface so you can validate the experience.

Here is a list of prototyping tools to build sites and apps for desktop and mobile devices. There are tools with templates and built-in design elements for animations, gestures, transitions, and customized content. Most of these tools come with a price tag but some give free access for a single project or limited pages, letting you find the right application for your project.

1. Figma

Figma is a browser-based UI and UX design application, with excellent design, prototyping, and code-generation tools. It’s currently (arguably) the industry’s leading interface design tool, with robust features that support teams working on every phase of the design process.

There are few free kits on Figma, but the ones available can help mobile developers get started. The latest iOS Facebook kit and Android UI kit are ready to use. There is also a link to Figma Resources where the community submits the latest mockups, icons, kits, and other resources.
