Responsively App vs Hoverify for responsive testing
Both put your page on a wall of devices with mirrored scrolling. 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. Its unified inspector reaches every preview at once, it screenshots the whole wall in one click, and a community of contributors keeps it moving. For an occasional layout check, it's hard to argue with free.
Pick Hoverify if
You test pages that sit behind a login, or you'd rather not run another app. The device wall opens in your own browser, so your session, your cookies and your ad blocker all carry over. It also comes with eight other tools, which is what the price is actually buying.

A Responsively App alternative in your browser
Most Responsively frustrations we hear about 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 and its one inspector spanning every device, and you pay for the toolkit around it.
