9 website prototyping tools for UX and UI designers

Prototypes use the power of staging to help designers understand how a site’s user experience (UX) functions in practice. Unlike static mockups, these tools show how pages connect, how visitors move through the site, and how interface details respond. 

With website prototyping tools, you can create and compare multiple builds to see which one suits your client’s needs. This makes your path to launch clearer with fewer late-stage surprises. Collaborative and interactive prototyping platforms are particularly useful for this kind of testing. Clients can view the latest mockups as you make changes, and you can collect feedback to make improvements that fit their vision.

In this guide, we’ll compare nine popular prototyping tools for UX design to help you find the one that best supports your workflow.

What are prototyping tools?

Prototyping tools help developers and designers create interactive mockups that show how a website should behave before it goes live. They give a website its working shape, which makes it easier to test user journeys and interactive features.

With these tools, early-stage web design can feel more like a testable beta than a brainstorming session. Clients can see whether the site’s logic matches their goals, while you can catch usability issues before the final development stages.

What to look for in a prototyping tool

There’s no one-size-fits-all rule for prototyping tools, but there are some key elements to look for:

• Ease of use. Prototyping tools should help you build quickly without burying common actions behind a steep learning curve. Speed and usability matter most when projects need fast iterations or when clients want to review prototypes without your guidance.
• Features. Consider the level of fidelity and functionality your projects require. Some tools are better for rough wireframes, while others enable you to create interactive prototypes with animations and other complex features.
• Compatibility. Check to see whether the tool works smoothly with your asset libraries and integrates with your shared project management stack, so you don’t have to redesign your entire workflow.
• Collaboration features. Real-time collaboration features, like comments, version histories, and editing permissions, keep feedback within the workspace.
• Device preview options. A prototyping tool should show if your website is responsive across screen sizes. This way, you can catch layout and usability issues and give clients a realistic idea of the final experience.
• Interactivity and animations. If you often build rich sites with many animations, look for a prototyping tool with more robust features that can preview how menus open, buttons respond, and transitions function.
• Customer support and documentation. Helpful documentation and reliable customer support save time when you need to learn about a feature or problem-solve, especially during tight deadlines.
• Cost. A free or lower-cost plan may work for solo projects, while client-heavy agencies will likely need paid features for collaboration, permissions, and developer handoff.

9 prototyping tools for UI/UX designers

Here are nine examples of strong prototyping tools that cover everything from simple, low-fidelity wireframes to full mockups.

1. Figma

2. Miro

3. Flinto

4. Axure RP

5. Origami Studio

6. Justinmind

7. Proto.io

8. Principle

9. Mockplus RP

1. Figma

With Figma, you can create high-fidelity, visual-first prototypes in the same workspace you design the site’s interface. This shared space makes it faster to view and act on feedback, because you won’t need to rebuild screens in a separate tool, then import it back into Figma.

For handoff, Dev Mode helps developers inspect implementation details, while Code Connect links design components to real code. Figma also has AI-assisted workflows through Figma Make, which turns text prompts into functional prototypes or web apps.

Pricing (referenced May 2026): 

• Free Starter plan available.
• Professional plan starting at $16 per month for a full seat.
• Organization plan starting at $55 per month for a full seat.
• Enterprise plan starting at $90 per month for a full seat.

Best suited for: Teams that need one workspace to handle realistic website prototypes, client reviews, and developer handoffs while reusing components between projects.

2. Miro

Miro is a prototyping tool that’s useful for clients stuck in the ideation phase. In early stages when your client’s website idea still needs shape, you can use Miro’s AI to turn notes from a range of sources (including screenshots and text prompts) into prototypes.

Miro supports drag-and-drop visual editing and accepts notes directly on the prototype, so it’s clear what parts client comments refer to. Since the tool lets you create multiple versions of one site to compare in one window, you can show clients your thought process to narrow down the design direction while changes are still low-stakes.

Pricing (referenced May 2026): 

• Free plan available.
• Starter plan starting at $8 per month per user.
• Business plan starting at $20 per month per user.
• Enterprise plan available for a minimum of 30 members at a custom price.

Best suited for: Design teams that need a collaborative space to turn design ideas into clickable concepts for discovery workshops, strategy sessions, and/or early client reviews.

3. Flinto

Flinto is a beginner-friendly Mac and iOS-based prototyping tool. Its Transition Designer lets you create animated screen-to-screen movements without timelines or programming, while Behavior Designer handles smaller interactions, such as button states and looping effects. 

This prototyping tool is user-friendly for designers who want to add motion without moving into a more technical or code-heavy environment. You can also import designs from Figma or Sketch and preview them on an iOS device through Flinto’s viewer app, which is useful for checking responsive designs.

Pricing (referenced May 2026):

• $99 each for one to four copies.
• $89 each for five to nine copies.
• $79 each for 10+ copies.

Best suited for: Designers working in Mac ecosystems who want a tool for animated, interactive prototypes.

4. Axure RP

Axure RP’s strength lies in its logic-heavy UX prototyping rather than visual design. You can use features like working forms, sortable grids, and conditional logic to test how a complex website might respond to various user choices before moving into development.

This tool works best for enterprise projects where clients need to see gated paths. Axure also supports documentation inside the same workflow, so you can collaborate with stakeholders and get approval in one space.

Pricing (referenced May 2026):

• Axure RP Pro starting at $29 per month per user.
• Axure RP Team starting at $49 per month per user.
• Enterprise plan at a custom price.

Best suited for: UI/UX teams working on enterprise websites or projects with deep client involvement, where testing and reviewing documentation before development is critical.
