Alloy - AI prototyping with your real app

Hi Product Hunt community 👋🏻
I’m Simon, and I'm incredibly excited to introduce Alloy – a new type of AI prototyping tool, built for product leaders. Alloy lets you capture your app from the browser, and instantly explore feature ideas that perfectly match your design.

AI prototyping with your real product
Don't waste credits using tools that force you to start from scratch. Alloy is built for teams that already have a product. Capture it from the browser in seconds and watch as your ideas come to life.

The future of Product Management

Traditional PM workflows are changing faster than ever. Rather than describing the design you want through product requirements, you can now create a prototype in plain english to communicate the ideas in your head. Unlike other tools, these will fit right into your existing app's design. It's a whole new way for product leaders to explore more ideas, and move faster than they ever could before.

Alloy is free forever

We believe the future of making products should be open to everyone. Alloy will always be available to try for free, with a paid pro plan that lets you unlock more features and get extra value from AI.

Would love to hear what you think or what you'd like to see next!

P.S. Code is "PH50" for 50% off Pro for 3 months!

Hey everyone — Christian here, co-founder and CTO of Alloy.

Really appreciate all the support so far. We’ve been genuinely overwhelmed by the response and the number of teams already putting Alloy into their workflow.

Our focus now is shipping the things you’ve been asking for most:

• Libraries & Components — automatic component capture so you can reuse real UI instantly

• Multi-page capture for stitching together broader flows

• Deeper workflow integrations with Linear, GitHub, and Figma

If you’ve tried Alloy, keep the feedback coming — it’s directly shaping what we build next. Thanks again for the momentum.

Been mind-blown by this! It’s incredible prototyping ideas in seconds on your real product.

Ideas are fragile at first and sometimes hard to communicate. Too many great thoughts never see the day of light because others couldn’t be convinced of it. Alloy flips this upside down. It lets you build something that others can see and feel. That’s incredible powerful.

Congrats on the launch, great team!

Alloy surprised me in the best way. It lets you tweak and refine your existing product with nothing but prompts, and the crazy part is… it actually works. You’re essentially prototyping on top of your real product instead of recreating everything from scratch.

It’s not one of those tools you “get” by reading comments. You have to try it for ten minutes and watch it bend your product into new shapes. After that, you just nod and think, alright, this is some sorcery.

If you’re in product and constantly iterating, Alloy feels less like a tool and more like an unfair advantage. Give it a spin. You’ll understand.

Still amazed at how effectively Alloy was able to automatically import all our brand style guides from our website! Congrats on the launch @iaculch @simonkubica and team 🎉

This has been such a useful Product for our team to help us iterate faster for our startup

So good! I love how easy it is to jump start every idea not having to start from scratch. It makes it feel much more real too, unlike the stuff I build in other tools. It also goes so fast, there is literally zero friction. Love it.

This looks super useful, best of luck with the launch.

QQ -- how does it work with existing CSS/SCSS files? Is it good at taking and working with existing style sheets, or is it deriving those from pages and URLs provided?

As someone who prototypes a lot, this feels… refreshing.
Not having to redraw the whole app just to test an idea saves a ton of time. Nice work!
