Alloy

Create AI prototypes that look exactly like your product. Capture any page instantly and build interactive demos to share with your team.

Alloy is a prototyping tool for product managers and product teams who want to explore ideas on top of their existing product. Users capture pages with a browser extension or connect their codebase, then prompt changes that use their real components, design system and tokens. Alloy runs the app in a cloud sandbox with a live preview, and every session can be shared by link for comments from teammates or customers. Changes can be pushed as a GitHub pull request, exported, or accessed via MCP. It also offers Figma import and export, over 20 integrations, MCP connectors, and the option to use an existing Claude or ChatGPT subscription.
