Responsively

Responsively is a specialized browser built for web developers working on responsive designs. It displays your website across multiple device screens simultaneously, eliminating the need to manually resize browser windows or switch between device emulators. All devices show your site in real-time, and any interaction you make on one device automatically replicates across all others.

The tool includes a unified inspector that works across all devices at once, allowing you to examine element details without switching contexts. You can take comprehensive screenshots of all devices with a single click, and save custom device combinations as 'Preview Suits' for quick switching between testing scenarios. It comes with extensive pre-configured device profiles while also supporting custom device definitions.

Web developers and designers benefit most from Responsively when building or debugging responsive websites. It's particularly useful for spotting layout inconsistencies across devices, testing interactive elements simultaneously, and creating comprehensive documentation with multi-device screenshots. The open-source nature means developers can contribute to its development and customize it for specific workflows.
