What is Alloy.app?

AI prototyping platform that lets product teams build and share interactive demos using their real product codebase.

Alloy is a cloud playground for product teams to build and prototype using their real product. It allows users to connect their codebase or capture pages via a browser extension, then prompt changes that are reflected instantly in a sandboxed environment. Sessions can be shared via links, and changes can be pushed to production as pull requests. Integrates with Slack and other tools to turn ideas into prototypes directly from conversations.

Use Cases

Product managers capture their web app and prompt new features, then share a live prototype with stakeholders for instant feedback without writing code.
Designers use the browser extension to capture existing pages and quickly iterate on UI changes, ensuring prototypes match the real product's design system.
Engineering teams connect their codebase to Alloy, allowing non-developers to propose changes that are automatically translated into production-ready code and pushed as pull requests.
Customer success teams turn Slack messages from clients into interactive prototypes by mentioning @alloy, enabling rapid validation of feature requests.
Product leaders organize prototypes into folders by project or team, keeping the workspace clean and enabling parallel exploration of multiple ideas.
During sprint planning, teams use Alloy to quickly mock up solutions for user stories, reducing the time from idea to demo from days to minutes.
Stakeholders review prototypes with a clean preview link (no Alloy chrome), focusing solely on the proposed changes during customer walkthroughs.
