Alloy is an AI-powered product prototyping platform designed for product managers, designers, engineers, founders, and customer-facing teams. Instead of generating a generic interface from scratch, Alloy can begin with an organization’s existing product. Users can capture live application pages through its browser extension or connect a GitHub codebase, allowing the platform to understand the product’s current components, design patterns, pages, and visual identity.

Once the source is connected, users can describe a feature or interface change through conversational prompts. Alloy generates the proposed experience inside a browser-based sandbox, where teams can preview it, edit individual elements, refine the result through follow-up instructions, and test how the idea fits within the existing product. It can also capture multi-page workflows, form interactions, navigation steps, and modal behavior, making it suitable for prototyping complete user journeys rather than isolated screens.

Every session can be shared through a cloud link for stakeholder or customer feedback. Team members can leave comments, while presentation controls allow creators to hide Alloy’s interface when presenting a cleaner product demonstration. Prototypes can also be organized into folders for larger workspaces and ongoing product initiatives.

Alloy connects with product-management, collaboration, support, sales, and engineering tools. Integrations include Slack, Microsoft Teams, Linear, Jira, Notion, Productboard, GitHub, Zendesk, Intercom, Salesforce, HubSpot, Dovetail, Zapier, and many others. These connections can transform feature requests, support tickets, research findings, CRM notes, and project tasks directly into prototypes.

For implementation, Alloy can export sessions, expose them through MCP, or turn codebase-based changes into GitHub pull requests. It offers web, Windows, macOS, iOS, and Android access, alongside its Chromium browser extension.
