The 11 Best Prototyping Tools For Startups

Figma

Figma is the go-to tool for creating interactive prototypes and detailed designs, especially when you’re working with others. The real-time collaboration means everyone can work on the same project at once, which saves time and keeps everyone on the same page.

You can build everything from basic wireframes to high-fidelity prototypes that feel like the real product. The prototyping features let you add animations, transitions, and clickable elements that show exactly how users will interact with your design. This helps you test ideas before any code gets written, which can save significant development costs down the line.

But that’s not all, there’s more:

• You can choose from device templates for mobile, tablet, and desktop to make sure your designs work across different screen sizes
• The reusable components feature helps you maintain consistency throughout your designs – change a button style once and it updates everywhere
• You can share prototypes with stakeholders through a simple link and collect feedback directly on the design
• Figma integrates with tools like Slack and Dropbox to fit smoothly into your existing workflow

While Figma has become the industry standard for UI/UX design, it does have some limitations to consider. You need a stable internet connection since it’s cloud-based, and occasional lag can happen during peak times. The recent pricing changes mean costs have gone up for some teams, with enterprise seats now costing $75 to $90 and organisation seats increasing to $45 to $55. For complete beginners, there’s a learning curve to understand all the features, though the basics are fairly intuitive once you get started.

Marvel App

If you want everything in one place – from wireframes to user testing – Marvel App might be your solution. It brings together your entire design process, letting you create wireframes, build interactive prototypes, and test them with real users all in the same platform.

What’s interesting here is that Marvel App covers the complete workflow. You start with basic wireframes using drag-and-drop templates, then add interactions to create clickable prototypes, and finally test those prototypes with actual users. The platform claims you can transform designs into interactive prototypes in less than five minutes without writing any code.

But that’s not all, there’s more:

• You can watch how users navigate your prototypes with screen, audio, and video recordings. This gives you real insight into what works and what doesn’t.
• The tool supports multiple devices including desktop, iPhone, iPad, and Android, so you can test across different platforms.
• You can work offline and present prototypes without needing an internet connection, which is handy for meetings or presentations.
• Marvel App integrates with other design tools, letting you import designs from Sketch or upload your own images to build upon.

The thing is, Marvel App positions itself as having everything you need in one place. Over two million people use it according to their website, ranging from Fortune 100 companies to startups and schools.

While Marvel App is great for startups wanting a complete workflow, it has some limitations to consider. The free plan has basic features, but you’ll need to upgrade to access more advanced user testing capabilities. Some users find that while it covers many bases, it might not have the depth of specialised tools for complex interactions or advanced animations. The pricing scales with projects and collaboration features, so costs can add up as your team grows.

Visily

Visily is an AI tool that turns your text into professional designs without needing any design skills. If you’re a startup founder, product manager, or anyone who needs to visualise ideas but isn’t a designer, this tool makes professional wireframing accessible.

Visily helps non-designers quickly convey product ideas to clients and executives with precision. You can start from a text prompt, upload a screenshot, or use one of their thousands of pre-built templates. The AI does the heavy lifting, converting your descriptions or images into editable wireframes that you can then customise.

But that’s not all, there’s more:

• You can use their Screenshot to Design AI feature to upload images of existing apps or websites and get editable wireframes in minutes. This is great for “borrowing” layouts from products you like.
• Their text-to-diagram feature lets you simply describe what you need, and the AI generates the design for you. No need to know design terminology or principles.
• You get access to a library of pre-made components and templates that work across different device types, so you’re not starting from scratch every time.
• The drag-and-drop interface makes it easy to adjust the AI-generated designs, giving you control without requiring design expertise.
• They offer a Chrome extension that lets you capture ideas directly from your browser and turn them into actionable designs.

Visily was specifically built for non-designers, which means there’s virtually no learning curve. Unlike professional design tools that can take weeks to master, you can start creating usable wireframes in your first session.

While Visily is great for making design accessible, it does have some limitations. The AI-generated designs might need more manual refinement for complex projects compared to what a professional designer would produce. Also, while the free Starter plan gives you access to their AI models and templates, you might need to upgrade for team collaboration features or more advanced projects.

Miro

Miro is perfect for product managers who need to visualise design ideas, map out user journeys, and create basic wireframes all in one collaborative space.

You can use digital sticky notes, drawings, and diagrams to quickly sketch out product concepts. The platform helps you break down complex ideas into manageable pieces that everyone can see and contribute to.

What’s interesting is how it brings stakeholders together – developers, designers, and business folks can all add their perspective right on the same board.

But that’s not all, there’s more:

• You can access hundreds of templates for wireframes, user journey maps, and product roadmaps that give you a head start on any project
• You can integrate Miro with tools like Slack, Google Drive, and Jira to keep your workflow smooth and connected
• You can create interactive prototypes that stakeholders can click through and test directly in their browser
• You can gather real-time feedback with comments and annotations that everyone on the team can see and respond to

While Miro is great for collaborative brainstorming and early-stage prototyping, it has some limitations to consider. For new users, the platform can feel overwhelming with all its features and options. If you’re looking for highly detailed, pixel-perfect prototypes, you might need to pair Miro with more specialised design tools. The pricing can also be a bit steep for smaller startups, especially if you need advanced features or larger team plans.

Banani

Banani uses AI to create high-fidelity UI designs that match your visual identity, then lets you export everything to Figma for further refinement. It’s perfect for startups that need consistent branding but don’t have a full design team yet.

You start by giving Banani a text prompt or uploading an image reference. The AI then generates complete UI designs that actually look like they belong to your brand. The tool adapts to your brand styles, so colours, typography, and spacing all feel cohesive right from the start. This means you get professional-looking prototypes without spending hours tweaking every element.

But that’s not all, there’s more:

• You can use AI chat editing to refine specific parts of your designs, asking the tool to adjust layouts or change components through simple conversations
• The side-by-side canvas views let you compare different design variations as you work, helping you make better decisions faster
• When you’re ready, you export everything to Figma with a simple copy-paste process, just like moving designs between Figma files
• The tool generates full design flows, not just single screens, so you get complete user journeys that make sense together

The Figma export is what really sets Banani apart. You’re not stuck with static images or limited prototypes – you get editable designs that fit right into your existing design workflow. This bridges the gap between AI generation and professional design tools.

While Banani is great for creating polished, on-brand prototypes quickly, it has some things to consider. The AI-generated designs might need some manual tweaking in Figma to get exactly what you want. You’re also relying on the AI’s understanding of your brand, which can sometimes miss subtle nuances. For complex interactions or very specific design systems, you might still need a human designer’s touch after the initial generation.

Axure RP

When you need to prototype complex user interactions with conditional logic and dynamic content, Axure RP gives you the precision and depth that simpler tools can’t match. This tool is built for detailed UX workflows where you want to show exactly how different user choices lead to different outcomes.

Axure RP lets you create prototypes that feel like real applications. You can build working forms, sortable grids, and interfaces that respond to user inputs. The conditional logic feature means you can create prototypes that branch based on what users do, which is perfect for testing complex user flows.

But that’s not all, there’s more:

• You can create everything from simple conditions that affect single interactions to complex branching logic that controls entire prototype areas
• The dynamic panels feature lets you nest widgets within panels, making it easier to manage complex interface elements
• You can quickly align items within parent containers and select elements on the canvas with precision
• The tool supports working forms and data-driven interfaces that mimic real application behaviour

The thing is, Axure RP really shines when you’re dealing with complex user flows that need realistic prototyping. According to their documentation, conditional flows in Axure RP are some of the most powerful ways to demonstrate multiple sequences to stakeholders and users during testing.

While Axure RP is great for detailed UX workflows, it has some limitations you should know about. The learning curve is quite steep, especially for beginners who aren’t used to complex interaction design tools. You’ll need to invest time to understand how to make the interactions work exactly as you want them to.

Also, if you’re working on simple prototypes or just need basic wireframes, Axure RP might feel like overkill. The complexity that makes it powerful for detailed workflows can be overwhelming for straightforward projects. The tool works best when you need that level of precision and conditional logic that simpler prototyping tools just can’t provide.

ProtoPie

ProtoPie is a prototyping tool that lets you build high-fidelity interactive experiences with realistic user flows, all through a visual interface.

You can design prototypes that respond to device sensors like tilt, sound, and camera inputs. This means you can create experiences where users tilt their phone to navigate, use their camera to scan QR codes, or trigger actions with sound. These sensor-based interactions make your prototypes feel incredibly real.

But that’s not all, there’s more:

• You can create dynamic interactions like validating email addresses in real-time or animating objects with intricate motion patterns using logic, variables, and formulas
• You can import designs directly from Sketch, Figma, and Adobe XD, then add complex interactions on top of them without starting from scratch
• You can build reusable interaction components that save you time on future projects and keep your design system consistent
• You can prototype across multiple devices and screen sizes, testing how your interactions work on different platforms

The tool is particularly good for simulating realistic user experiences. You can create prototypes that respond to user inputs in sophisticated ways, like showing loading states, error messages, or success animations that match what the final app would do.

While ProtoPie is great for creating high-fidelity interactive prototypes, it has some limitations. The learning curve can be steep if you’re new to advanced prototyping concepts. The pricing structure changed in 2024, and some users found the new plans less generous with cloud storage. For simple wireframes or basic click-through prototypes, ProtoPie might be overkill compared to simpler tools.

Framer

Framer does double duty – it’s perfect for creating interactive website prototypes with AI assistance, and it also provides an integrated platform that combines design, prototyping, and publishing.

You can build layouts, add clickable elements, and create animations that make your prototypes feel like real apps or websites. The AI features help you skip the blank canvas phase by generating page layouts and components in seconds, which is especially helpful when you’re starting a new project.

But that’s not all, there’s more:

• You can use Framer’s AI tools like Wireframer and Workshop to generate designs and layouts based on what you’re trying to build, which speeds up the initial design phase
• You can define transitions, hover effects, and add animations that make your prototype engaging and realistic, perfect for showing stakeholders how the final product will work
• You can publish your designs directly from Framer, creating live websites without needing separate hosting or development tools
• You can collaborate with team members in real-time, sharing designs and getting feedback all within the same platform
• You can create reusable components and styles to keep your designs consistent across different pages or projects

While Framer is great for creating visually appealing and interactive websites, it has some limitations you should know about. According to the NoCode Alliance, Framer lacks robust backend capabilities, making it unsuitable for building full-fledged web applications with complex server-side logic. This means it’s better for portfolios, landing pages, and small business sites rather than large-scale applications with thousands of product listings or advanced filtering needs.

Also, if you’re coming from a tool like Figma, you might find the learning curve manageable since Framer’s interface is designed to feel familiar, but some advanced features can take time to master. The pricing can also be a consideration for startups with tight budgets, especially if you need access to all the AI features and publishing capabilities.
