Preview websites on many device sizes at once

About Responsively App

Responsively App is a free, open-source desktop browser that mirrors a site across many device viewports simultaneously with synchronized scrolling and clicking for responsive development. Frontend developers catch layout breaks across sizes in one glance instead of resizing repeatedly. In practice, it is the kind of single-purpose tool people keep bookmarked for a recurring job, and users usually compare it on speed, limits, privacy handling, and whether it works without registration.
