Polypane is a web development browser that streamlines the process of creating and testing modern websites. Its standout feature is the ability to display multiple screen sizes simultaneously, with synchronized scrolling and interactions, allowing developers to assess various layouts and breakpoints at once. It also emphasizes accessibility tools, real-time previews, and debugging capabilities.
Kilian Valkhof, founder of Polypane, discusses his career and the development of the browser with Josh Goldberg. Josh is an independent open source developer contributing to the TypeScript ecosystem and works on tools like typescript-eslint. He is a Microsoft MVP and author of “Learning TypeScript,” and frequently shares his expertise through talks and workshops.
