What tool do you use for creating wireframes/mockups?

Balsimq (quick) & Figma (detailed)

Adobe XD makes it possible to create the wireframe, mockup, and prototype in the same design file, so you don't have to integrate multiple tools or re-export dozens of times with each iteration. Fragomen Connect Portal

Visily is the most powerful AI-enabled wireframing tool that I've seen. The tool creates better looking wireframes compared to old-age tools like Balsamiq. Their customer support is really on point too. https://www.visily.ai
