Responsively

A modified browser for responsive web development

Open SourceFree TierAdded Apr 1, 2020

About

Responsively is a free, open-source developer tool that lets you see your website across multiple screen sizes simultaneously in a single window. All viewports are mirrored — scroll, click, or navigate in one, and all others follow. Hot-reloading support, screenshot tools, and network throttling built in. A massive time-saver for responsive web development.

Origin Story

By Manoj Vivek

The Problem

Resizing the browser window or switching between device emulators to test responsive designs was painfully slow and repetitive.

Building It

Launched in 2020. Quickly went viral in the developer community. 20K+ GitHub stars.

What It Means

A simple, focused developer tool that does one thing perfectly — multi-screen preview with mirrored interaction.

The Dream

To make responsive web development a joy instead of a chore.
