Responsively App vs Hoverify for responsive testing
Both put your page on a wall of devices and mirror your scrolling, clicks and typing across it. The fork in the road is where that wall lives: Responsively builds it in its own desktop app, Hoverify builds it in the browser you're already signed into. One of these is ours, so read with that in mind.
Where each tool wins
The feature lists overlap more here than on any other comparison we've written, so the decision mostly comes down to app or extension.
Use Responsively if
You want a free, open-source tool and a dedicated window for device testing. It ships 120 device profiles, each with its own user agent. Its unified inspector reaches every preview at once, and it screenshots the whole wall in one click. For an occasional layout check, it's hard to argue with free.
Pick Hoverify if
You test pages behind a login, or you'd rather not run another app. The device wall opens in your own browser with your session, cookies and ad blocker. Devices get frames and Safari or Chrome bars, and in Chromium browsers your mouse works like a finger. The price also buys eight other tools.

A Responsively App alternative in your browser
Most of the reasons people go looking for a Responsively alternative trace back to one architectural fact, and it's the same fact that makes the app appealing in the first place.
Responsively is its own application, and that cuts both ways. A separate app means a separate profile: pages that need a login want signing into again, sites with strict auth flows have drawn a steady trickle of bug reports from users who couldn't get in at all, and the extensions you rely on while browsing don't exist inside it.
Hoverify skips the problem instead of solving it. The device wall opens in the browser where you're already signed in, so a staging site behind SSO or a checkout flow mid-payment renders in every preview exactly as it does in your tab. The trade is real, though: you give up Responsively's dedicated window, its per-device user agents and its one inspector spanning every device, and you pay for the toolkit around it.
