@kilianvalkhof this is so cool! Is there an option to flip all devices landscape? working on my landscape mobile experience

@thekiddewey Hi Alex, Polypane knows about portrait vs. landscape on mobile and tablet devices. Each pane can be flipped between portrait and landscape by double clicking the width or height, and if you change a pane it will remember being landscape or portrait!

@kilianvalkhof Ace! thanks. Found this on the right day! I'd like to see maybe a shortcut to flip all panes at once but aside from that looks good - Great job

@thekiddewey good idea! I'll see if I can get it into the next update.

Hey all!

First off, thanks @kevin for hunting Polypane!

With Polypane, I want to build the browser for developers, designers and everyone else that works with the web. It's filled with features that make you more efficient and help you develop faster.

I've been working on this since 2015, starting with seeing if I could get a browser to display a site at multiple responsive breakpoints. From there, I've just been improving and expanding the concept into a fully featured browser with really unique features for developers and designers.

As a solo developer, designing and building everything is an incredible amount of work, but it's so amazingly rewarding.

I can't wait to see what you all think of Polypane. It sounds like hyperbole, but compared to developing sites using Chrome or Firefox, developing in Polypane takes just half the time (I tested and verified this, many times, over the past few years). I have good hopes that your experiences will show a similar improvement.

Whats new since your last launch?

@aaronoleary Hi Aaron! Back in 2017 I posted the first beta on Producthunt (I had been working on it since 2015) and that was a very minimal concept: it showed your site in multiple panes, you could generate a screenshot and that was it. Since then I've been steadily improving Polypane and getting feedback from beta testers. Polypane now syncs all your actions between panes, it knows about common device sizes and about your sites CSS breakpoints. The entire browser is zoomable so you can even design for 4K screens on an ultraportable. There's a ton more features in there (css layout debugging, focus mode, pane zooming) and even more that'll be implemented in the coming months and years.
