# Alloy > Alloy is an AI prototyping tool for product teams. Capture any live web app, including logged-in screens, and turn it into a pixel-perfect, editable prototype in seconds. Describe changes in plain language and share high-fidelity prototypes that look exactly like your real product. Alloy (formerly Index) is made by Index Technologies Pty Ltd, a Y Combinator company founded in 2023 and headquartered in Surry Hills, Sydney, Australia. Also referred to as Alloy AI, Alloy app, or Alloy Prototyping. Not affiliated with Alloy Automation, Alloy identity verification, or alloy wheel companies. Key benefits: - Prototype on your existing product instead of a blank canvas - Matches your design system and reuses your real components, fonts, and data - Works on authenticated pages via the Chrome extension, or on any public URL via the website cloner - No IDEs or terminals: runs entirely in the browser - Cloud agents connect to your codebase so prototypes can become pull requests Key features: - Free AI website cloner: paste a URL and get an editable copy of any page - Chat and visual editing to change captured screens with AI - Multi-page capture flows for onboarding, checkout, and other journeys - Shareable prototype links, inline comments, and feedback collection - Integrations with Linear, Jira, Slack, GitHub, Figma, Notion, Confluence, and more - MCP server so Claude, ChatGPT, Codex, and Cursor can create and edit Alloy prototypes - Bring your own Claude or ChatGPT subscription ## Product pages - [Home: AI prototyping tool for product managers](https://alloy.app/) - [Free AI website cloner](https://alloy.app/website-cloner) - [Screenshot to code](https://alloy.app/tools/screenshot-to-code) - [Image to HTML](https://alloy.app/tools/image-to-html) - [HTML to design](https://alloy.app/tools/html-to-design) - [Cloud agents platform](https://alloy.app/cloud-agents) - [Design system prototyping](https://alloy.app/design-system-prototyping) - [Vibe design](https://alloy.app/vibe-design) - [Pricing](https://alloy.app/pricing) - [Integrations](https://alloy.app/integrations) ## Documentation - [Quick start](https://alloy.app/guide/quick-start) - [Browser extension](https://alloy.app/guide/browser-extension) - [How to capture a page](https://alloy.app/guide/how-to-capture) - [How to prototype](https://alloy.app/guide/how-to-prototype) - [Public links](https://alloy.app/guide/public-url) - [Export code](https://alloy.app/guide/export-code) - [GitHub codebase connectivity](https://alloy.app/guide/github-codebase-connectivity) - [MCP integration for Claude, ChatGPT, Codex, and Cursor](https://alloy.app/guide/integrations/mcp) - [Billing and plans](https://alloy.app/guide/billing-and-plans) - [Security and data protection](https://alloy.app/security) ## Library (guides and comparisons) - [Library index](https://alloy.app/library) - [Best AI prototyping tools](https://alloy.app/library/best-ai-prototyping-tools) - [Best wireframing software](https://alloy.app/library/wireframing-software) - [How to clone a website](https://alloy.app/library/how-to-clone-a-website) - [What is AI prototyping](https://alloy.app/library/what-is-ai-prototyping) - [What is a cloud agent](https://alloy.app/library/what-is-cloud-agent-new-layer-ai-native-product-development) - [Figma Make vs Claude Design](https://alloy.app/library/figma-make-vs-claude-design) - [Magic Patterns reviews, pricing, and alternatives](https://alloy.app/library/magic-patterns-reviews-pricing-and-alternatives) - [AI for product managers](https://alloy.app/library/ai-for-product-managers-guide) ## Resources - [Launches and changelog](https://alloy.app/launches) - [Company news](https://alloy.app/company) - [Press](https://alloy.app/press) - [Careers](https://alloy.app/careers) - [Simon Kubica, co-founder and CEO](https://alloy.app/people/simonkubica) ## Get started - [Log in or sign up](https://alloy.app/login) - [Pricing](https://alloy.app/pricing) - [Contact sales or support](https://alloy.app/contact) ## Legal - [Privacy policy](https://alloy.app/legal/privacy) - [Terms of use](https://alloy.app/legal/terms-of-use) - [Data processing agreement](https://alloy.app/legal/dpa) - [Responsible disclosure](https://alloy.app/security/responsible-disclosure)
