Polypane is a brand that offers a stand-alone browser designed to help ambitious web developers build responsive, accessible, and fast websites. With all the necessary tools in one app, Polypane simplifies the development process, allowing developers to focus on their craft and polish their websites. Polypane caters to developers, designers, QA professionals, and marketers looking to improve their workflow.

The browser provides a comprehensive set of features, including responsive design for viewing mobile screens to 5K monitors, accessibility tools to ensure that websites work for everyone, and site quality tools to enhance the user experience across devices and networks. Polypane goes beyond simply identifying issues with a website; it is prescriptive, providing actionable insights on what needs improvement and how to achieve it. This saves developers valuable time and eliminates the need for third-party tests.

Founded by Kilian, a web developer with nearly 20 years of experience, Polypane was born out of the frustration of constantly resizing browsers. Kilian's goal is to create the perfect browser for developers and designers, and he is committed to continuously enhancing Polypane. In addition to Polypane, Kilian also works on other projects, including Superposition and FromScratch, and actively contributes to the open-source community.
