Alloy

Alloy is an AI prototyping tool for product managers (AI Prototyping for Product Managers), and its core idea is to let product managers directly prototype and make changes based on a real product, rather than drawing mockups from scratch or pasting screenshots.

Purpose and positioning Alloy is used for product prototype exploration and iteration. You can clone your own product or web app, make changes instantly, and share high-fidelity prototypes with stakeholders as a link. The official description calls it "AI prototyping with your real product."

Main capabilities

1. Build prototypes based on a real product: You can use your existing codebase, components, and pages to explore product ideas.
2. Build ideas instantly: Modify the product through prompts, then share it, and you can push production-grade code.
3. Live preview in the browser: Alloy runs your app in a sandbox, and the results of prompt-based changes can be viewed in real time.
4. Link sharing: Every session exists in the cloud and can be shared instantly with your team or clients via a link. The examples show two types of permissions: "Anyone at Airbnb Full access" and "Anyone with the link Public."
5. Integrate existing sources of ideas: You can get ideas, insights, and customer requests from more than 20 integrations and build directly in Alloy.
6. Skip developer handoff: Changes are built on top of your codebase and can be pushed as a Pull Request at any time.
7. Feedback and delivery workflow: Share a link and collect feedback through comments; open a Pull Request to push changes to clients; no need to struggle with a local development environment anymore.
8. Enterprise-oriented: The official description says it is "Enterprise Ready. Built to Scale." and emphasizes treating security as an engineering standard rather than a badge list, with every part of the platform designed to keep data secure.

Feature updates (release items listed on the official page)

• Figma import and export (October 8, 2026): Turn Figma designs into runnable prototypes, and also bring prototype interfaces back into Figma. You can explore ideas in Alloy first, then continue refining them with the design team.
• Libraries and components (September 1, 2026): Upload your design system as a library, and save part of a prototype as a reusable component. Alloy's agent builds using your real components, tokens, and assets.
• Bring your own subscription (Bring your own subscription, August 13, 2026): You can use your existing Claude or ChatGPT subscription to power Alloy sessions. The account only needs to be connected once, and prompts on supported models will run through your plan instead of consuming Alloy credits.
• MCP connectors (August 13, 2026): Connect Alloy agents to the SaaS tools your team already uses. Authorize a provider, or add any compatible remote MCP server, to use its tools in Alloy sessions.

How to use it The official FAQ gives several usage paths:

• Connect a codebase: This lets Alloy run the entire application and write production code, but it requires admin permissions and takes about 15 minutes to set up.
• Browser extension: No setup required, it can instantly capture your product and let you start prototyping right away, suitable for rapid visual prototypes.
• Sessions can be launched from the cloud or started from Slack, support parallel runs, can be shared with teammates or clients, and can be pushed to GitHub without complex setup.
• Figma import: In an Alloy Pro workspace, open the "+" menu in the prompt box, select "Import from Figma", connect a Figma account, and paste a frame or Figma Design link. The official documentation states that Figma Make files are not currently supported. All workspaces can export the current prototype interface: in the export menu, select Figma, click Copy, and then paste it into a Figma Design file.
• Code export: Every Alloy session can be exported, accessed via MCP, or converted into a Pull Request on GitHub.

Differences from Claude Code and other app-building tools The official explanation for this is: Alloy lets anyone in the company launch sessions from the cloud, without needing to run a developer environment on a local machine; sessions can be started from Slack, run in parallel, be shared with teammates or clients, and be pushed to GitHub without complex setup. Compared with other app-building tools, Alloy starts from your existing product and writes production code that can be pushed to customers; it understands your product, component library, and design system, so the build results automatically look like they were made by a designer, which the official documentation calls "vibe design with your existing product."

Applicablescenarios

• Product managers quickly validate and present product ideas;
• Create high-fidelity prototypes based on existing products, design systems, and component libraries;
• Collaborate back and forth with the design team in Figma;
• Collect feedback through comments and ultimately turn it into a Pull Request;
• Launch prototype sessions in parallel from Slack or the cloud.

Limitations and notes

• Connecting a codebase requires admin permissions and about 15 minutes of setup time; the browser extension requires no setup.
• Figma Make files are not currently supported for import.
• Regarding pricing, costs, specific plan credits, available platforms, and similar information, the existing materials do not provide this, so it is not currently available.
