1. UXPin — Best for Production-Fidelity Prototyping
UXPin is a code-based design and prototyping tool where AI generation, professional design capabilities, and production code output all operate from the same source of truth — your actual component library. Unlike image-based tools, UXPin prototypes are fully interactive: forms accept input, states change dynamically, and conditional logic drives real user flows.
AI-Powered Design with Forge
UXPin Forge is an AI design assistant that generates, edits, and iterates on UI layouts using real React components from your production design system — not generic pixels. You can prompt Forge with text descriptions, upload a reference image, or paste a URL, and it produces a working layout that you can refine with professional design tools.
Because Forge is constrained to your team’s actual component library, every AI-generated screen is automatically on-brand and technically implementable. The output is exportable as production-ready JSX. Teams report 8.6x faster design-to-prototype cycles when combining Forge with Merge.
Code-Backed Components with Merge
UXPin Merge lets designers build prototypes using the exact same React, Angular, or web components that developers use in production. Sync your component library via Git integration, npm, or the Storybook integration.
Pre-built libraries are available for popular frameworks including MUI (Material UI), shadcn/ui, Bootstrap, and Ant Design.
The result: prototypes that look and behave exactly like the final product. Developers can copy clean JSX directly from Spec Mode — enterprise teams using Merge report up to a 50% reduction in engineering time for UI implementation.
Advanced Prototyping Features
Beyond AI and code-backed components, UXPin includes built-in features that most tools need plugins for:
- States — Create multi-state components (tabs, toggles, accordions) without separate frames
- Variables — Store and reuse values across a prototype to simulate real data flow
- Conditional Interactions — Build “if/then” logic that adapts the prototype to user input
- Expressions — Use JavaScript-like expressions for calculations and dynamic content
- Auto Layout — Flexbox-based layout that mirrors production CSS behavior
- Built-in Accessibility Checker — Validate contrast ratios and accessibility during design
UXPin is available as a desktop app (Mac & Windows) and in the browser. Prototypes can be tested on any device using shareable links or the UXPin Mirror mobile app.
Best for: Teams that need high-fidelity, interactive prototypes with real code output — especially enterprise design teams managing complex design systems.

2. Figma — Best for Collaborative Design and Basic Prototyping
Figma is the most widely adopted design tool globally, known for its real-time collaboration, extensive community resources, and robust plugin ecosystem. Figma’s prototyping features let you create click-through prototypes with transitions, animations, and basic interactive components.
Prototyping Strengths
- Real-time multiplayer editing for team collaboration
- Component variants and interactive components for basic state changes
- Smart Animate for smooth transitions between frames
- Massive community with free templates, plugins, and UI kits
- Browser-based with desktop apps for Mac and Windows
Prototyping Limitations
While Figma is excellent for visual design, its prototyping has notable gaps for advanced workflows. Form inputs remain limited — you cannot test flows that require users to type information. Conditional logic, dynamic data, and multi-state interactions require workarounds with multiple frames rather than built-in functionality.
Figma prototypes are image-based, meaning they approximate the final product visually but don’t replicate production behavior. This can lead to usability testing results that miss issues only visible with real component behavior.
Best for: Design teams focused on visual design and collaboration who need basic prototyping for early-stage concept validation.
For a detailed breakdown, see our UXPin vs Figma comparison. You can also import Figma designs into UXPin for interactive prototyping.
3. Framer — Best for Web-Focused Design and Publishing
Framer has evolved from a prototyping tool into a web design and publishing platform. Its AI feature lets you describe a website layout and receive a customizable design instantly — making it one of the fastest options for creating web prototypes.
Prototyping Strengths
- AI-powered site generation from text descriptions
- Direct publishing to live websites with hosting included
- Layout tools and an Insert Menu for rapid design iteration
- Smart Components with Variants and Variables for interactive states
- Built-in CMS for content-driven websites
Prototyping Limitations
Framer is optimized for marketing websites and landing pages rather than complex application UIs. It lacks the deep interactivity features (conditional logic, expressions, multi-state components) needed for prototyping enterprise dashboards, forms-heavy workflows, or multi-step user flows. Its output is Framer-specific code, not reusable production components.
Best for: Designers and small teams building marketing websites, landing pages, and portfolio sites who want to go from design to live site quickly.
4. Axure RP — Best for Complex Enterprise Prototyping
Axure RP has been an industry standard for enterprise UX prototyping for over a decade. It offers deep conditional logic, data-driven content, and comprehensive documentation capabilities that make it popular with UX teams working on complex enterprise applications.
Prototyping Strengths
- Conditional logic and dynamic panels for complex interaction flows
- Repeaters for data-driven prototypes (tables, lists, feeds)
- Built-in documentation and specification features
- Robust support for form validation and multi-step workflows
- Team projects with version control
Prototyping Limitations
Axure’s visual design capabilities feel dated compared to modern tools. The learning curve is steep, and prototypes don’t produce reusable production code. Collaboration is less fluid than browser-native tools, and the community and ecosystem are smaller than Figma’s or UXPin’s.
Best for: Enterprise UX teams that need to prototype complex, logic-heavy workflows with detailed documentation — especially in regulated industries like healthcare and finance.
5. ProtoPie — Best for Advanced Animations and Multi-Device Prototyping
ProtoPie specializes in creating sophisticated interaction prototypes with realistic animations, gesture support, and sensor-based triggers. It’s the tool of choice when you need to prototype experiences that go beyond screen taps — including voice, tilt, proximity, and multi-device communication.
Prototyping Strengths
- Advanced animation and micro-interaction design
- Sensor-based interactions (gyroscope, sound, camera)
- Multi-device prototyping — screens communicate with each other
- Import designs from Figma, Sketch, or Adobe XD
- ProtoPie Connect for in-venue demos and kiosk prototypes
Prototyping Limitations
ProtoPie is a prototyping-only tool — you cannot do visual design work inside it. Designs must be imported from other tools, adding a step to the workflow. It doesn’t generate production code, and its strengths are most relevant for mobile and IoT experiences rather than standard web application design.
Best for: Teams prototyping mobile apps, IoT interfaces, automotive dashboards, or any experience that requires realistic animations and sensor-based interactions.
