Frequently Asked Questions

What rendering engine does Polypane use?

Polypane is based on Chromium version 102, and is continuously updated as Chromium versions get released.

What operating systems does Polypane support?

Polypane runs on Windows, Mac and Linux. We have universal builds to support Intel, Apple Silicon and ARM processors. For Linux we have a .deb and .AppImage available.

How does Polypane work?

Polypane runs multiple Chromium instances for your site, letting you configure each of them with different emulation settings. Then it syncs all user input across these devices (from scrolling to keyboard shortcuts, hovers included), so you only have to interact with one to test them all.
At the same time, it analyses your CSS, HTML, storage, meta data and more to automatically lint every part of your web page.

When is Polypane a bad fit?

Polypane is a browser built for developers, so it assumes your website is reasonably well built. It does not try to compensate for poor or slow code (slow code especially is noticable when you run the same slow code simultaneously half a dozen times).

Because Polypane is based on Chromium, it also will not help you with issues specific to Safari or Firefox. Even if you use a developer browser, you should still test in multiple rendering engines.

Can I test all browsers in Polypane?

It’s not possible to show all rendering engines in a single, cross-platform browser. Under the hood Polypane uses the Chromium engine, the same as Chrome, Edge, Brave and many other browsers. It renders sites the same as the vast majority of browsers.

Polypane can also emulate other browsers like Safari for iOS or Firefox. This means your site’s JS will think it’s running in them and you can use that to test specific fallback logic. The underlying rendering engine is still Chromium though, so a real Safari or Firefox can render things differently.

Even if you use a developer browser, you should still test in multiple rendering engines.

What is your roadmap?

We do not publish a public roadmap, but are very responsive to user requests and input. User requests are added as votes to our (extensive, 5+ year) internal roadmap and new features are planned according to popularity.
