About Responsively
Responsively is a web development tool that lets you view and test responsive designs across multiple devices side by side. It targets web developers and QA teams who need to verify layouts quickly, with real-time synchronized interactions and device previews.

Key Features
When evaluating responsive behavior, users rely on a unified view and synchronized actions across devices to spot issues quickly:
All Devices at Once
See all device previews side-by-side in one view, no more fiddling with the devtools resizer.
Mirrored Interactions
Any click, scroll or navigation you perform on one device is replicated across all devices in real time.
Preview Suits
Save favorite device combinations and switch between them quickly when testing.
One Click Screenshots
Take full-page screenshots of all devices at once with a single click, or grab individual device shots via the toolbar.
Summary
Best for frontend teams, QA testers, and design leads working on responsive layouts.
