Polypane

Features

Polypane is a powerful browser and development tool that makes you faster and more productive.

View your site at all sizes

Stop resizing your browser. Use Polypane to see the full range of viewports for your site in a single overview.

Use popular devices

With a list of popular device sizes, checking to see if your site or app renders well on user devices becomes easy and fast.

Or use the site's breakpoints

Prefer using content instead of devices? With Polypane's breakpoint detection you can easily create panes for each breakpoint in your css.

One-click screenshots

With a single click you can generate a screenshot with a full overview of your site at all screen sizes and share it with anyone.

All your actions are synced

Interact with one pane and all other panes will automatically follow your actions. Scrolling, clicks and hovers are automatically shared between panes. Easily verify that your site works as intended on all viewports.

Focus mode

Use focus mode to work on a website with a single view center stage. Quickly resize the pane to try out different sizes.

Powerful devtools

With powerful Chromium-based devtools, Polypane has your back when it comes to debugging your website.

Layout debugging

With a single toggle Polypane will show you how the layout of the page is built up, helping you quickly find out where layout issues come from.

Zoom your browser

Zoom single panes, or your entire list of panes to get an even better overview of your website.

Discover how much time you can save by having a complete overview of your site or app.
