Firefox already has a Responsive Design Mode [0] that does this, but for one pane. Combine that with a tiling window manager and you get everything except the pane mirroring without having to use a proprietary browser.

I'd be interested in knowing if any other solutions exist just to add in the syncing functionality.

Edit: a comment mentioned Browsersync [1]. Browsersync + a proper window manager should give you everything Polypane offers and more, with any browser.

BrowserSync[0] has syncing different tabs, reloading the page on code changes, layout mode, and many other features. It basically does what Polypane seems to do, and it's FOSS. The only thing missing is, as you mentioned, multiple windows side-by-side, and you can pretty much do that manually (or with a tiling WM - which you already mentioned).

browsersync is nice but it's just a different approach (proxying for multiple clients/tabs) with its own tradeoffs.

Polypane is one browser tab (1 debugger, 1 css editor, etc) with multiple viewports, so there's no extra hassle or window-management involved when inspecting an element, editing a style, hitting a breakpoint, etc.

All chromium browsers had this for a long time. The point is - nobody really provided a feature to have N views with different resolutions for the same source

Blisk, Sizzy have been around for a while and do exactly this. Plus I remember something (maybe Rocketmelt?) offering a similar feature waaay back.

We stand corrected then.

There's also Emmet Re:view, an open source Chrome extension (apparently not actively developed though): https://github.com/emmetio/re-view

browsersync syncs up everything, so I'm sort of failing to see the difference between this and a few tiled windows side by side (what I currently do) with browsersync sync'ing scrolling and clicking. You're likely already using it as part of your webpack dev flow anyways.
