Alloy

Alloy is an AI prototyping tool that lets product managers, designers, and founders build interactive prototypes using their existing product, not a blank canvas. Connect Alloy to Claude to capture, clone, and modify web apps and websites, then iterate with AI cloud agents that run in the background.

With the Alloy connector, Claude can:

Clone any website or web app — capture live pages with Alloy's website cloner and turn them into editable, high-fidelity prototypes in seconds Prototype on your existing product — import your real UI via browser capture and test new features, flows, and redesigns in context, without engineering time

Run cloud agents — delegate multi-step prototyping and editing tasks to Alloy's AI agents and pull results back into your Claude conversation

Manage projects and prototypes — create, list, edit, and share Alloy projects directly from Claude

Alloy is built for product teams who need to communicate ideas visually: PMs validating concepts before writing a PRD, designers exploring variants of live pages, and founders demoing features that don't exist yet. Unlike generic AI app builders, Alloy works from your existing product's real code and design system, so prototypes look and feel like the real thing.
