Every package Responsively App depends on, ranked by repo health score.
Responsively App is a purpose-built desktop browser for web developers that renders your website in multiple device viewports at once. Instead of tediously switching between browser DevTools presets or physically resizing a window, you get a unified panel showing every screen size side by side, all reacting to your changes in real time.
At its core, the app embeds real Chromium-based webviews inside an Electron shell, so rendering is pixel-accurate — not emulated. Interactions are synchronized via BrowserSync: scroll one device and every other scrolls with it; click a link and all devices navigate together. This eliminates the repetitive manual testing loop that eats hours of every responsive-design cycle.
The tool ships with over 30 built-in device profiles spanning iPhones, iPads, Android handsets and tablets, and common desktop breakpoints. A custom device manager lets you add your own dimensions with DPR, touch capability, and user agent settings. Multiple preview layouts — flex wrap, masonry, and individual focus mode — adapt to different workflow preferences. Full-page screenshots across all devices are captured with a single click.
Responsively App is fully free and open source under the AGPL-3.0 license, with pre-built installers for macOS, Windows, and Linux available through the project website or package managers like Homebrew, Chocolatey, and winget.
