With so many different free prototyping options available, figuring out which one is right for you is tough. You need all of the essential features to create interactive and visual representations of products during the design phase and avoid costly rework during the product development process, but you still have to stick to a limited budget. I've got you! In this post I'll help make your choice easy, sharing my experiences using multiple free tools with larger teams and dozens of product launches on a tight budget, with my picks of the best free prototyping tools.  

What Are Free Prototyping Tools?

A free prototyping tool is a type of software that allows users to create interactive prototypes at no cost. These tools are often suitable for individuals or small teams with budget constraints, providing a platform to visualize and test design concepts without the financial commitment associated with premium prototyping software.

Expect to see basic interactive elements, ease of sharing prototypes, and limited but functional design capabilities. While they may not have all the advanced features of premium tools, free prototyping tools can help validate concepts without the need for a financial investment.

Selection Criteria for the Best Free Prototyping Tools

Here are a few of the top factors I took into account when I was researching the best free prototyping tools for this list:

Core Functionality

At their core, prototyping platforms are a type of product design software that should help you build and iterate on your digital product. I looked for platforms with design tools that can help you with ui prototyping and general web design.

Key Features

These are a few of the top features I looked for in these software:

  1. Rapid prototyping: The ability to quickly and efficiently produce low-fidelity prototypes helps your design team get the ball rolling.
  2. Drag-and-drop editor: This can also speed up prototyping, and facilitates real-time collaboration among team members.
  3. Interactive prototypes: Especially for high-fidelity prototypes with UI elements to be tested, tools should go beyond a static design.
  4. Wireframing: A wireframing tool allows your product designers to craft a mockup of a web app, mobile app, or other digital product.
  5. Testing: Ideally, you want a tool that can test your prototype across android, iOS, mac, windows, or specific web browsers.


The best prototyping software will come with a minimal learning curve and be accessible to beginners. Features like templates, tutorials, and a drag-and-drop interface make it easier for design teams to create with the software. But these features also make it easier for stakeholders to review the work, and support a better handoff to the development team.


How a new tool fits in with your existing tech stack is always something to consider before purchasing. Some of these platforms have plugins and widgets to connect other apps and tools. Many also have APIs that can be used to build custom integrations. I’ve provided details on the integrations available for each platform.


Of course, because I was looking for free options, I was checking out the price point of each tool before including it on the list. To qualify for my ‘free’ list, I was ideally looking for software with a free plan. That said, some options with generous free trials also made it onto my list. Paid plans tend to range between $7-$30 per user, per month.

FAQ: Common Questions About Prototyping and Product Design

Still have some questions about designing and prototyping web-based products? Here are a few answers to common questions:

What is the role of prototyping in product design?

Prototyping is the stage in product design at which you turn product ideas and concepts into tangible, testable outputs. It’s the bridge between brainstorming and bringing a new product to market. Prototyping can also be a stage of product iteration, when you’re testing out new features or functionality within an existing product.

When it comes to web-based products like web and mobile apps prototyping is all about crafting an intuitive UI with smooth transitions and easy navigation. Everything from the fonts you use to the workflow a user has to advance through contribute to the overall user experience of your product. With a prototype, you can run user testing on all of these factors and collect feedback to improve your product before you launch it.

What is the difference between a wireframe, prototype, and mockup?

Wireframes, prototypes, and mockups are three distinct parts of the design process, and each serves a specific purpose. Here’s a breakdown of what each one does:

  1. Wireframes are a basic, simplified visual representation of a design or interface. They focus on the structure, layout, and hierarchy of elements, and are typically created early in the design process to serve as a blueprint for the overall design. They use simple shapes, lines, and placeholders to represent different components, content blocks, and UI elements.
  2. Prototypes are interactive models or working versions of a design that simulates the functionality of the final product. While wireframes are typically static designs, prototypes are interactive and offer a more realistic user experience. Prototypes are used to test and validate the design, gather user feedback, and refine the user experience. This helps designers identify and address usability issues before proceeding to the development phase.
  3. Mockups are another type of static design, but offer a visual representation of the final design of a product. They showcase the ultimate appearance, colors, fonts, and overall visual style of a product design. Mockups are more polished and detailed compared to wireframes and prototypes. They can be created with mockup tools and are commonly used for presentations, client or stakeholder approvals, and marketing materials.
