Our desks used to be full of devices – iphone, android phone, ipad, macbook and windows laptop. Refreshing all the screens to see if the client's website looked great at different viewpoints took time. Probably 40% of the build time is QA and testing. Polypane solves this problem by letting you view multiple viewports and set guides/rulers to see if everything lines up as you scroll.

The passion of the creator and constant improvement. We mostly use this for testing website responsive viewport sizes side-by-side, but there is so much more here.

The refresh icon was on the right side of the address bar (a hang over of previous browser UI), but this changed last year. The expereince is seamless coming from using F12 in Chrome.

The ability to view my website in both the mobile, tablet and desktop view has made me and my clients happy when working. Previously I used some other browsers which of course didn't show some of the bugs in the design/development process. All I can say is, it has saved me a lot of time and money, all in one!

There was an inability to scroll in my panes but hopefully this bug will be fixed in the next release.

Polypane is really good and i love the appearance and it functionalities.

Polypane is featured packed, and the deviation from traditional browsers. I loke it speed and multiple pane pictures. It has a brilliant staff management's to manage memory.

Due to the massive features and deviations from traditional browsers, it takes a while to know how polypane works.

It's new and professional. I see myself using it a lot in feature.

I like the responsiveness in terms of moving the pages around and especially the interface.

I have not found anything discouraging about the App but I have experienced some functional inadequacies like not being able to submit a form across all screen sizes with a click from one screen resolution and struggling to find the settings icon.
