Are there any platforms or tools to create a responsive prototype?
Actually most modern wireframing tools offer this option (in different ways).
Figma is great for building with responsive constraints — you can stretch your layouts and see how they will respond to changes in screen size. (If you’re new to constraints in Figma, check out this beginner primer here.)
Adaptive Views - in Axure you basically just create different screens that trigger at certain breakpoints.
Adaptive views are alternate versions of pages designed for specific screen sizes. They allow you to create a page once and then rearrange, resize, and restyle its widgets to fit each screen size you intend to test it on.
When you view the page in a web browser, the appropriate view for the browser dimensions will be shown automatically.
Adobe XD has some responsive features now that might help your design along. Here is the intro video from Adobe that will give you some insight: https://www.youtube.com/watch?v=BKvg8_8jv10
