What is Alloy?
Alloy is an AI prototyping tool for product managers. It lets you start from your existing product, not a blank canvas. You can connect your codebase or use a browser extension to capture your web app. Then you make changes by chatting, and Alloy writes production-ready code that fits your design system.
To get started, you either add the browser extension with no setup or connect your codebase, which takes about 15 minutes and admin permissions. Once connected, you prompt changes like adding a bulk select feature. Alloy runs your app in a sandbox so you can preview changes live. You can share sessions with teammates or customers via a link, and every session lives in the cloud.
Alloy suits product managers, designers, and teams who want to explore ideas quickly without leaving their real product. It integrates with over 20 tools for ideas and feedback. You can export sessions to Figma or push them as pull requests to GitHub. The website does not list specific pricing details, but you can start for free.

Tips for better results with Alloy
- Connect your codebase rather than using only the browser extension so Alloy can run your full app and write production code that matches your design system.
- Start each session with a specific, focused change like adding a bulk select feature, and review the live sandbox preview before sharing the link with stakeholders.
- Use Alloy's chat to iterate on a prototype by prompting small tweaks one at a time, which helps the tool apply changes cleanly and keeps the session easy to follow.
- Share your Alloy session link with teammates or customers for feedback early, then push the final version as a pull request to GitHub when it's ready to ship.

What to check before you rely on Alloy
- Check the pricing page for plan limits and costs, since the website lists a free start but does not state specific pricing details or what the freemium tier includes.
- Verify that your codebase connection works with your admin permissions and that Alloy's sandbox can run your app, as setup takes about 15 minutes.
- Confirm your data and privacy needs are met, as the website mentions security standards but does not detail specific compliance or data handling policies.
