Prototyping works better than a thousand meetings.

After all, a prototype is something your future users and stakeholders can see and click through. Which is a great way to collect their feedback and make your product better – at an early stage, not when it’s almost finished.

That’s why designers try to do their best on this stage, and the right tools can surely help.

But it’s hard to get lost in the huge number of apps – free, paid, web-based and desktop ones.

To help you pick the right software, I’ve listed 9 best prototyping tools for 2023, both trendy and effective.

Let’s check them out.

Top Free Prototyping Tools

What’s the point in spending hundreds on software when you can use free prototyping tools?

But there’s a catch – free tools are mostly simple, with limited functionality. They won’t work if you’re working on UI/UX design with a large team of developers.

Still, if you’re working on a single project like your business website, free tools may be more than enough.

I’ve collected a few prototyping tools you may want to try out – and it won’t cost you a penny.


Platforms: web, iOS, Android

  • User testing. As UX plays a crucial role in the creation of any digital product, designers may get feedback from users during beta testing and make changes to meet customers’ needs.
  • Automated design specs creation. Marvel has an integrated Handoff tool that lets designers hand over their design to developers by sending them a URL.

It’s pretty easy to use Marvel app –  its interface is clear, so even beginners can deal with it.
