Responsively App

Responsively App is a modified browser, built with Electron, that displays a web page on many devices at once, side by side. It helps check responsive layouts without resizing the browser or switching between device emulators.

User interactions such as scrolling, clicks and navigation are mirrored across all devices. The preview layout can be customised, one elements inspector works for all devices, and more than 30 built-in device profiles are provided, with the option to add custom devices. Screenshots of all devices can be taken in one click, and hot reloading is supported during development.

Responsively App runs on Windows, macOS and Linux. It is free and open source under the AGPL-3.0 licence.
