Framer
Also runs on Web. A browser tool for designing and publishing websites, with hosting and a CMS on paid plans. It suits marketing sites more than app interfaces, so it ranks lower for UI work.

Axure RP
A desktop prototyping tool for detailed interactive specifications, with a free 30-day trial. Its learning curve is steep, and paid licenses apply after the trial.

Webflow
Also runs on Web. Visual website builder for designers, with hosting on paid plans. It is closer to Framer than to Figma, because it builds live websites rather than interface mockups.

Balsamiq
Also runs on Web. Browser-based wireframes that keep reviews on structure rather than visual detail, with free reviewers. It is paid per editor and is not built for pixel-level UI design, so Figma and Penpot in this list fit that work better.
Best for Low-fidelity wireframes and early product flows
