Alloy

Alloy is an AI-powered prototyping tool designed for product managers and product teams who want to create high-fidelity prototypes that look exactly like their real product. Using a browser extension, teams can capture their product's design system with a single click and then use a chat interface to prototype new features that automatically match their existing visual style. No coding, design system imports, or engineering tools are required — Alloy works directly from your live web app. Teams use Alloy to explore UI concepts, test ideas with users, and clarify requirements before handing off to development.

• Browser Extension Capture: Install the Alloy Chrome extension, open it on any page of your app, and capture your product's design system instantly — no setup required.
• AI Chat Prototyping: Use the chat interface to describe changes or new features; Alloy generates on-brand prototypes that blend seamlessly with your existing UI.
• On-Brand Results: Unlike screenshot-based tools, Alloy understands your component library and design system, ensuring every prototype looks like it was made by your designer.
• Instant Sharing: Share prototypes with teammates, stakeholders, and customers immediately via a shareable link, with unlimited viewers on all plans.
• React Code Export: Export your prototype as a React app for handoff to engineering (available on Pro plan).
• Figma Export: Export any Alloy prototype to Figma at any time using the built-in Figma button.
• 20+ Integrations: Connect with tools like Linear, Jira, Slack, and Intercom to pull in ideas, insights, and customer requests directly into your prototyping workflow.
• Team & Admin Controls: Pro and Enterprise plans include admin roles, design system controls, SAML + SCIM, and API access for larger organizations.
• Enterprise Security: SOC 2 Type II report, SAML + Google SSO, custom terms, and uptime SLA available for enterprise customers.
