Alloy is a browser-based AI-powered prototyping tool designed to convert existing web app interfaces into editable, high-fidelity prototypes quickly and efficiently. It enables product managers, founders, and UX strategists to capture their actual product interfaces and modify them using AI, without relying on designers or traditional mockups. This approach accelerates the prototyping process by maintaining full design system consistency and eliminating the need for code changes or exporting from design tools like Figma.

Key features of Alloy include zero-setup deployment, AI-driven editing and feature creation, and realistic prototype generation that mirrors the real product’s look and feel. The app supports rapid iteration for user validation and stakeholder feedback while preserving brand and design integrity. Alloy is built to fit the needs of modern product teams emphasizing speed, realism, and effective collaboration.

By leveraging your actual product interface as the foundation and using intelligent AI prompting, Alloy streamlines the transition from concept to validated prototype, supporting efficient product development workflows without extensive design dependencies or coding constraints.
