What is Alloy?
Alloy is a sophisticated, lifelike prototyping tool specifically designed for professional product teams. It fundamentally solves the challenge of creating high-fidelity, on-brand prototypes quickly by capturing your existing web application pages and components directly from the browser. This approach allows Product Managers and designers to instantly validate new ideas and features that look exactly like the final product, drastically accelerating the idea-to-validation cycle.
Key Features
🌐 Direct Component and Design System Capture
Use the dedicated browser extension to capture live product pages and their underlying components instantly. Alloy understands your product's design system, eliminating manual setup and the need to import assets. The result is that every new prototype is automatically pixel-perfect and consistent with your existing brand identity.
💬 AI-Driven Prototyping via Chat
Leverage a powerful, prompt-based chat interface to instantly kick off new ideas, complex changes, or feature additions directly onto the captured page. This method is ideal for rapid iteration and conceptualizing complex workflows. For polishing and precise adjustments, you can seamlessly switch to visual editing tools, combining the speed of AI with granular control.
🔗 Seamless Workflow Integration
Alloy is built to integrate into your existing discovery workflow. Connect to over 20 popular tools—including customer feedback platforms and insight repositories—to instantly turn raw ideas, insights, and customer requests into immediate, functional prototypes. This bridges the gap between understanding user needs and executing design concepts.
🚀 Instant, Secure Team & Customer Sharing
Prototypes are built for collaboration. Share your creations instantly with internal stakeholders or external customers via a secure link. You maintain control over permissions and can enable external viewers to see the prototype in action without exposing internal details like chat history or versioning, facilitating rapid and confidential user testing.
Use Cases
Alloy is tailored to enable speed and fidelity across critical product development stages:
1. Rapid Feature Validation Before Engineering Handoff Instead of spending days creating static mockups or low-fidelity wireframes, capture your live dashboard or application page. Use the AI chat prompt to instantly overlay a new feature (e.g., "Add a new filter panel here for shipment status" or "Redesign the primary navigation to include a notifications icon"). Share the realistic prototype with stakeholders immediately to gather high-quality feedback, saving significant design and engineering time by validating the concept earlier.
2. High-Fidelity User Testing When testing complex changes, such as modifying a checkout flow or updating a critical data entry sequence, realism is paramount for accurate user feedback. Since Alloy prototypes look exactly like the production environment, you can conduct user tests that generate trustworthy results, ensuring customers react to the proposed functionality, not the fidelity of the mockup.
3. Accelerating the Design-to-Code Loop For teams on the Pro plan, Alloy doesn't stop at visualization. Because the prototype is based on the actual product structure, you can export the resulting prototype as a functional React application. This provides engineers with a significant head start, offering a usable base for implementation and dramatically reducing the friction between prototyping and development.
Conclusion
Alloy fundamentally changes how product managers validate ideas by eliminating the friction between concept and realistic prototype. By leveraging the fidelity of your live product, you can ensure that your team spends less time building mockups and more time gathering meaningful insights. Start leveraging your existing product assets today to accelerate development, gather better feedback, and achieve product-market fit faster.
