Alloy

Description

Alloy is an AI prototyping tool built for product managers. It lets you start from your real product rather than a blank canvas: capture any page of your live app with a Chrome extension, or connect your codebase so Alloy can run your entire app and write production code. Because it understands your product, component library, and design system, prototypes automatically look like something your designer made.

Users make changes with a chat prompt, preview them live in a sandboxed browser, and share every session through a link with teammates or customers. Alloy supports multi-page product cloning, AI prototype generation on your real design system, AI chat redesign of any existing website, team collaboration, and 20-plus integrations that pull in ideas, insights, and customer requests.

Sessions can be started from the cloud, run in parallel, and shared without a local developer environment. Output is flexible: every session can be exported, accessed via MCP, or converted into a GitHub pull request, and prototypes can be exported to Figma. The browser extension requires no setup, while connecting a codebase takes admin permissions and around 15 minutes.

FAQ from Alloy

• How do I use my existing product in Alloy?

  Either connect your codebase or add the browser extension. The codebase lets Alloy run your entire app and write production code, while the browser extension enables instant visual prototyping.

• How is Alloy different from other app builders?

  Alloy starts from your existing product and writes production code you can push to customers. It understands your product, component library, and design system, so everything you build looks on-brand.

• Does Alloy generate code I can use?

  Yes. Every session can be exported, accessed via MCP, or converted to a pull request in GitHub.

• Is any setup required?

  The browser extension requires no setup and captures your product instantly. Connecting a codebase requires admin permissions and around 15 minutes of setup.

• Can I import from Figma?

  Not yet, though it is in progress. For now you get the best results by capturing your actual web app, and you can export an Alloy prototype to Figma at any time.

• How is it different from a coding assistant?

  Alloy lets anyone in your company start a session from the cloud without a local developer environment. Sessions can start from Slack, run in parallel, be shared, and be pushed to GitHub without complex setup.
