Polypane: Responsive Website Testing on Multiple Devices
Explore Polypane, a web browser for developers and designers, offering simultaneous device testing, CSS editing, network analysis, and element measurement.
What is Polypane?
Polypane is a web browser that is purpose-built for web developers and designers. It aims to streamline the testing and debugging process when building responsive websites and web apps.
One of the key features that sets Polypane apart from traditional browsers is its ability to show you a website rendered on multiple devices at the same time. You can add smartphone, tablet, laptop, and desktop viewports side-by-side to see how your site looks across screen sizes. This makes responsive design testing much faster.
Beyond responsive testing, Polypane includes a number of tools to improve workflow compared to using the web inspector in a typical browser:
- Edit CSS live and see changes reflected instantly
- Measure elements and spacing directly on the page
- View network request waterfalls to analyze assets and performance
- Integrates with Browserstack for remote device testing
- Javascript and CSS error reporting
- Works as Chrome extension or standalone app
With its emphasis on responsive testing and building sites for modern devices, Polypane is optimized for web designers, frontend developers, and UI/UX experts who want to streamline their testing and debugging process.
