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. Kilian Valkhof is the Founder of Polypane which develops the Polypane browser. In this episode he speaks with Josh Goldberg about his career and the creation of his browser. Josh Goldberg is an independent full time open source developer in the TypeScript ecosystem.
