Alloy

AI prototyping tool that helps product managers build and test ideas fast.

Visit Alloy

Alloy is an AI prototyping app that lets teams clone their existing product or web app and explore changes through chat prompts, producing high-fidelity prototypes that can be shared with stakeholders. It works from a connected codebase or a browser capture extension, runs the app in a sandbox for live preview, and can push changes to a GitHub pull request.

Core capabilities include design system libraries and reusable components, inline comments, MCP connectors, and integrations with tools such as Jira, Linear, Notion, Slack, GitHub, Figma, Intercom, and Zapier. Sessions run in the cloud, can be shared via link, and support export to Figma or code. Users can connect their own Claude or ChatGPT subscription to power sessions.

Alloy is aimed at product teams and is packaged in three tiers: a free plan with unlimited users and monthly credits, a per-user Pro plan with additional credits and code export, and a custom-priced Enterprise plan with API access, SAML and SCIM, and an account manager.
