Explore ideas with AI prototypes that use your real app. Capture your app from the browser, describe features with AI chat, and get pixel-perfect interactive concepts you can share with your team and customers.
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!
Very cool stuff @simonkubica ! Plenty of use cases for this in B2B pre-sales I should think, as well as product
Awesome! I had the exact same idea, you beat me to it) Congratulations on the launch!
@simonkubica This looks like a perfect match with Gemini 3 Pro. Over the past few days I’ve seen lots of prototypes online that were built with Gemini 3 Pro. Do you already support Gemini 3, and are you planning any specific optimizations for it?
Love how it fits right into existing workflows, though I’m curious to see how it handles complex multi-page flows.
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!
This completely changes the game while discussing UX flows. Love what yall are doing here, this is going to become the standard pre figma step for us. Congratulations @iaculch @simonkubica
Alloy solves a very pertinent and interesting problem. We've faced this directly when trying to revamp the UX of our product. Using v0 for initial prototyping led to a split brain problem where designer, product manager and engineers had to keep translating between the product itself and the prototype in v0 which didn't adhere to the same look and feel and design system (despite numerous attempts to prompt it to do so).
Man just yesterday i wasted 2hrs tweaking a Figma mock to match our app UI.
You will be my hero if it works for me.
Incredible work Simon and Christian!
I was so very pleasantly surprised the first time I used Alloy on the Leonardo AI app, I thought that there was no way it would replicate it reliably, but it did 🤯
Keen to see Alloy continue to improve and make my and other product manager’s lives easier!!
The most practical AI prototyping tool I've tried so far. Being able to mirror our product from the get-go speeds up our development workflow and makes it so much easier to communicate the design.
AI prototyping with your real app is brilliant!
This could drastically reduce the feedback loop between design and development.
How does it handle complex state management scenarios?
I tested out this product and shared a prototype of a new feature i planned to share with customers. it was very exceptional. exceeded expectations for what i was expecting for a v1 product.
I’ve been using Alloy for a few months now and it’s solved something I’ve consistently hit walls on: making quick, targeted improvements to live pages where we don’t have proper designs in Figma. We’ve shipped a bunch of smaller features by just dropping an Alloy link in a Linear issue. The whole thing takes minutes. Thinking through the solution, improving it, done.
Pretty awesome way to quickly iterate on my ideas for my company without having to get engineering involved. Such a great use of gen AI that nobody has thought about yet! Well done!
Been using Alloy for a while now to mock up different ideas, and it's honestly awesome. I love it.
I tried Alloy a few days ago on an idea I’ve had in my head forever and was honestly surprised by how fast I got to something that felt real. I captured the page, tweaked the flow with a couple of prompts, and had a polished, clickable prototype in about 15 minutes ~ no design system setup, no assembling screens from scratch.
As a product designer, this is the first time a tool has made a ‘what if’ in my head feel like a real product experience this quickly. If you work in product and are constantly iterating, Alloy is definitely worth trying if you want to see what your ideas look like in a real product context!
All the best Team Alloy!
I have been following Alloy since launch but only got to try it recently. And, the moment I did there was no going back. I could see the power of this prototyping tool in the first few prompts and well before I exhausted my free trial credits. I have been able to iterate quickly and fine tune the experience to paint the vision. And, I have not even read the instructions on how to create effective prompts which goes to show the small learning curve to use Alloy. Great work, Simon and team! I am eager to see a native integration with Figma and also the ability to generate PRDs. That would amplify the value by several folds. Thanks!
