Alloy captures live product pages from the browser and converts them into lifelike, interactive prototypes that look and behave like the real product. It provides a browser extension and cross-platform apps (macOS, Windows, web, iOS, Android) to instantly capture UI, build pixel-perfect prototypes, and share them with teammates and customers. Alloy emphasizes realistic interaction fidelity and rapid iteration, with guided quick-start resources and AI-assisted prototyping to accelerate prototype creation. Mobile apps include real-time device communication features to support field collaboration and testing.
