About:
Polypane is a premium web browser built specifically for web developers and designers. It allows you to preview your projects across multiple simulated devices simultaneously in a single window, complete with built-in accessibility and performance auditing tools. This accelerates the development workflow by eliminating the need to constantly switch between different browser tabs or external device simulators.
Key Features:
  • Multi-pane view for simultaneous device testing
  • Built-in accessibility and performance audits
  • Live reloading and CSS editing across all panes
  • Simulates various vision deficiencies
Use Cases:
  • Responsive web design testing
  • Cross-browser compatibility checks
  • Web accessibility auditing
Alternatives:
  • Brave – Free, general-purpose browser with dev tools, but lacks multi-pane synchronized testing
  • Firefox Developer Edition – Free browser with excellent dev tools, but requires manual window management for multi-device testing
