Overview
Product summary
Review the store description, core capabilities, and common use cases.
Alloy is the world's first tool for prototypes that look exactly like your product. Capture any page of your web app from the browser and instantly turn it into an interactive prototype—perfect for exploring features, validating ideas, and sharing with stakeholders.
➤ What you can do
• Capture from the browser: One click to “Capture page” on any screen of your product.
• Get lifelike results: Prototypes stay on brand and reflect your component library and design system—no off-brand mockups.
• Design by conversation: Use natural-language prompts to add features, remix flows, and refine details; switch to visual editing when needed.
• Improve with every capture: Build a reusable library as you capture more pages; results get faster and more accurate.

Captured my app perfectly and was easy to design a feature on top with AI. Highly recommend connecting your codebase as well
Super easy to quickly generate new iterations of product screens so I can share with the eng team as context for their build out
Tried importing one of my webpages and asked it to add a couple of new elements. Completely didn't work, it just copies the HTML and takes an incredibly long time.
Incredible. Generates a lifelike version of my product quickly and seamlessly. Blows other AI prototyping tools I've used out of the water.
Epic product - going to use this every week
The extension is such a convenient and quick way to get the site content into the app for prototyping - great fidelity on that first copy
I think it could be great! Let's see where the development takes the product.
banger. such a useful
Its been on my wishlist to find an AI prototyping tool that actually works with existing products and designs. Previously you just had to accept that prototypes never looked and felt like your actual own software. Alloy is the only tool ive found that actually solves that, and generates designs ready for presentations - and that alone is worth 5 stars just to recommend others try it.
Crazy good! This will greatly help my workflow
