Balsamiq. It's a step up from paper and whiteboard. I do the first iteration in it to test out the flow. After that, I switch to Figma for the design system, branding and colors. Then I code.

All the designs are mostly suggestions, I usually don't try to be pixel perfect, just to be consistent visually.

I use it and love it. A great way to get a feel of the ui and ui copy. Makes it easy to add simple interactivity if you need a click through demo.

Nicely separates UX + ui from graphic design.
