Developer browser with panes, accessibility and meta views

About Polypane

Polypane is a Chromium-based browser for web developers showing multiple viewports side by side, plus built-in accessibility checks, social media previews, and performance insights. Developers building responsive, accessible sites do the whole job in one specialized browser. In practice, it is the kind of single-purpose tool people keep bookmarked for a recurring job, and users usually compare it on speed, limits, privacy handling, and whether it works without registration.
