Polypane is a specialized web development browser that simplifies creating and testing modern websites.

A key feature is that it provides multiple screen sizes at once, with synchronized scrolling and interactions,

so developers can test different layouts and breakpoints simultaneously.

Polypane also focuses on accessibility tools, real-time previews, and debugging features.

Kailien Balcoff is the founder of PolyPain, which develops the PolyPain browser.

In this episode, he speaks with Josh Goldberg about his career and the creation of his browser.

This episode is hosted by Josh Goldberg, an independent full-time open-source developer.

book, a Microsoft MVP for developer technologies, and a live code streamer on Twitch.
