help Responsively App FAQ

Is Responsively App free and open source?

Yes, Responsively App is a free and open-source tool available on GitHub, with a Chrome extension and desktop versions for Windows, macOS, and Linux. It is maintained as a community project and does not require a subscription.

Can Responsively App show multiple device viewports at the same time?

Yes, one of its core features is the ability to display multiple device screen sizes simultaneously side by side, so developers can see how a site looks on a phone, tablet, and desktop in real time. Scrolling and clicking are synced across all visible viewports.

Does Responsively App work as a Chrome DevTools extension or as a standalone app?

It functions as both—there is a Responsively App Chrome DevTools extension and a standalone desktop application built on Electron. The desktop version offers more features like screenshot capture and layout customization, while the extension integrates into your existing browser workflow.

How does Responsively App compare to Chrome's built-in device mode?

While Chrome's device mode lets you test one viewport at a time, Responsively App's main advantage is showing many viewports simultaneously with synchronized scrolling and interaction. It also provides quick access to commonly needed device profiles without manual configuration.
