Responsive design

Develop in multiple viewports at the same time

Polypane shows your site in multiple viewports at the same time, so you never have you resize your browser.

All your actions like scrolling, hovering, clicking and keyboard input are synced between all viewports.


Built-in Tailwind CSS breakpoints

Use the built-in Tailwind CSS breakpoints so you instantly get an overview of your site.

Using custom breakpoints? No problem, Polypane automatically detects those and makes panes with a single click.

Element editor

Add, edit and remove classes at lightning speed.

Apply Tailwind CSS classes to elements in all panes at once. See the effect on all screens at the same time.

Polypane automatically suggests classes from your CSS and HTML, and expands the class editor so you can see all your classes at a glance.

Side browser

Always have the Tailwind CSS docs at hand

With the Tailwind CSS documentation or your favorite Tailwind CSS cheatsheet in our side browser you never have to look far when you're looking something up.

Media Query emulation

Dark mode media query ready

Develop your site in light and dark mode at the same time, both in view and synced together. There is no faster way to build sites with dark and light mode.

Also works for reduced motion, color gamut and reduced data media queries!

Live reloading

Let us refresh the page.

With built-in live reloading it doesn't matter if you have a hot-reloading setup or not. Anyone using Polypane can get live reloading setup with a couple of mouse clicks regardless of your stack.

Chromium devtools included

Your favorite DevTools extensions

Install and use your favorite devtools, with support for React DevTools, Vue.js DevTools, Redux DevTools, Angular, Svelte and many more.
