Alloy

Alloy is a lifelike prototyping tool for product managers, built to turn ideas into believable product experiences. It recreates existing product pages in high-fidelity so new concepts begin on familiar ground. Alloy mirrors the user's component libraries and design systems, enabling flows with real UI parts instead of throwaway mockups. The result is a clickable, production-grade feel that helps teams evaluate usability, content, and edge cases before any code is written.
