Testimonials

Designers should confront themselves with the reality of different viewports as early and often as possible. Polypane encourages this behaviour, and makes it easy to do. It is easily one of the most useful tools for modern web designers and developers.

Stephen HayAuthor of Responsive Design Workflow

I’ve been using polypane recently. Not only is it convenient seeing your work in multiple responsive views at the same time, but doing that just helped me see a spacing issue between two breakpoints that I wasn’t aware of. Love it, 💯

I've been using Polypane for Letter, an email tool for designers, and Prototypr 3 - It feels just like Chrome/Safari/Firefox and performs just as fast. It helps me catch issues and the meta information preview is awesome. I can test all devices now so don't need to steal my grandma's iPad.

Graeme FultonFounder at Letter

Using Polypane and woah this is awesome! It helps you build responsive apps much easier and it’s really slick and fast! I was just 5 minutes in and I already fixed a bug. Holy s--t this is awesome.

Polypane has become an indispensable tool for my responsive design workflow. Just a bit of honest appreciation: excellent work.

Discovering Polypane was a game-changer to how I develop responsive websites. Being able to see how my site looks at multiple breakpoints offers a completely different perspective to my workflow. I couldn't imagine going back to using the Chrome inspector.

Julian KeenaghanCTO at Beam

As a marketing consultant, Polypane has allowed me to provide better feedback to our clients and prospects by reviewing their websites and landing pages in multiple viewports side-by-side. It has saved us countless hours when recording screen share videos, conducting landing page audits, and testing campaigns before they go live.

Polypane are building a smart design environment where you can preview your designs across a multitude of devices and viewports. An example of a workflow which considers the full context of the target medium.

I was very skeptical at first, but after finding myself annoyed at yet another responsive design, I decided to try Polypane. The first half hour in it solved the frustration I had with responsive design and I enjoyed it a lot. I really like it. Polypane works exactly how you imagine it should. I recommend it to anyone developing websites and apps.

With the new Polypane you can see the full range of viewports for your site in a single overview. With access to popular device sizes, your css breakpoints or by resizing panes manually. Interact with one pane and all other panes will automatically follow your actions. You can now stop resizing your browser. If you’re developing a website, Polypane comes in quite handy. Already an essential tool.

Polypane has made responsive development actually manageable, even for part-time developers like myself. With its detection of breakpoints, built in debugging tools, and how it "plays nicely" with other stack elements, it quickly became an indispensable part of my workflow. With tools like this, you have no excuse not to create great, responsive experiences!

Richard GoodwinDeveloper & Podcaster at Comedywham

Polypane is invaluable tool for responsive website testing. During development, it’s perfect on a second monitor to quickly see CSS changes at different screen sizes. And with a full set of dev-tools at hand, it is easy to tweak, test, and verify changes quickly. A must-have for front-end developers.
