Develop your site 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 again.

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.

Add, edit and remove classes at lightning speed.

Apply your Tailwind CSS classes to elements in all panes at once so you see the effect on all screens with the Polypane elements panel. The input field expands so you can always see all your classes.

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.

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.

Live reloading. For everyone.

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.

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.
