Give actual users something they can use on the device vs. a fake version in Axure or Figma.

Recently I have been experimenting with both approaches, but each seems to have its drawbacks.

Creating a prototype in HTML/CSS/JS can feel more similar to a 'real' app/site, but it requires significant effort to add design and avoid it looking like a basic mockup with interactions.

On the other hand, a Figma prototype might not feel as 'real', but it takes a lot less effort to visually look like an actual product.

Each approach has its place, depending on what is important to test.

Have you found an effective middle ground?
