Prototyping Design AI-Powered Product Teams UX/UI Branding No-Code

Overview

Alloy is a prototyping tool that allows product leaders to turn product ideas into realistic, on-brand prototypes in seconds. It can capture a product's real codebase or use a browser extension, and run the app in a sandbox. Alloy can be shared with team members or customers instantly, and changes can be pushed to a Pull Request at any time. The platform is designed for enterprise use and security is a top concern. One can access over 20 integrations and build ideas directly in Alloy, and the conversational voice mode allows users to describe changes while working in the background. Additionally, Slack integration enables users to turn any Slack message into an Alloy prototype. It offers a seamless experience where users can connect their codebase or capture pages from the browser extension and preview live in the browser. The platform ensures that everything built automatically looks like something a designer made, unlike other app builder tools.

I've evaluated a lot of these over the years. What stands out here is supports early-stage concept testing — handled better than most — and lowers barrier for non-designers. Generated designs may need manual refinement is my one real gripe. Worth the time if this is your use case.

Pretty happy overall. Realistic UI components and layouts just works and useful for early validation and stakeholder buy-in. Quality depends on prompt clarity can be annoying, but no dealbreakers — I'd recommend it to a friend without hesitating.

Q&A

How do I use my existing product in Alloy?

Either connect your codebase or add the browser extension. Using your codebase lets Alloy run your entire app and write production code, while the browser extension helps with instant visual prototyping.

How is Alloy different from Claude Code?

Alloy lets anyone in your company start a session from the cloud, without having to run a developer environment on their local machine. Sessions can be started from Slack, run in parallel, shared with teammates or customers, and pushed to GitHub without any complex setup work.

Asked by Omar Haddad · Aug 21, 2025

How is Alloy different from other app builder tools?

Alloy lets you start from your existing product and write production code you can push to customers. Rather than pasting in screenshots and getting off-brand results, Alloy understands your product, component library, and design system. Everything you build automatically looks like something your designer made.

Asked by Stella Papadopoulos · Aug 13, 2025

Is there any setup required?

The browser extension requires no setup and captures your product instantly, letting you start prototyping right away. When you're ready for more power, you can connect your codebase, which requires admin permissions and around 15 minutes of setup time.

Can I import from Figma?

Not right now, but we're working on it. For now you'll get the best results by capturing your actual web app, not Figma. You can export your Alloy prototype to Figma at any time by clicking the Figma button in the top right of your prototype.
