Vectr is a free graphics editor platform that helps design teams to create low-fidelity prototypes, wireframes, and mockups. The solution offers a wide variety of free tools, and you can export your creation to high-resolution image formats, such as PNG, JPG, or SVG. While this tool is not helpful for those looking for UI design or UX design solutions, it’s good for those who are looking for a simple web app wireframing tool.
The platform offers all the tools you need to create vector images, from canvas options to grids, vector pens, background removal, and freehand pencil tools. The main advantage of using this tool is that it’s completely free.
While you can’t create complex prototypes with it, it can still work as a great tool for wireframes, mockups, and simple web design prototypes.
Vectr is a free platform, with no hidden fees or costs.
Mockflow is a product design platform with good prototyping features. The software has a bit of a learning curve, but it comes with helpful documentation and tutorials to ease the accommodation process. The great thing about this solution is that it helps you organize your workspace. You can create different spaces for the different processes involved in prototyping, from ideation to feedback and execution.
There are a lot of templates and presets to choose from, so you can build a wireframe or a prototype in good time. You can mock-up user changes in a matter of minutes, and generate HTML to help your developers with the implementation.
Mockflow integrates with multiple tools, including Slack, Google Workspace, JIRA, Trello, Microsoft Teams, and more.
Mockflow is free for one user managing one project of up to three pages.

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