Free open source browser that shows many device sizes at once
Responsively App report card
Very good · out of 4.0 · graded Nov 13, 2026
Best for previewing a site on many screen sizes at once
Responsively App is a free open source browser that shows your site on many device sizes at once and mirrors your clicks across them. It uses Chromium, so it will not show you Safari or Firefox behaviour. It is for developers, not for everyday browsing.
Who Responsively App is for
- Fits if you build responsive sites and want to check many screens at once
- Works for front-end developers who want a free tool, not a subscription
Who Responsively App is not for
- Not for you if you want a daily browser, as it is a developer tool
- Skip it if you need Safari or Firefox engines, because it previews with Chromium
- Watch out: it runs on Mac, Windows and Linux only, with no mobile version
- Too light for debugging, as it has no extra tools listed beyond an inspector and screenshots
Why Responsively App gets a 3.0
Five grades, each with its reason. The GPA is their average: an A is 4 points, an F is none.
- AValue for moneyFree and open source, with no paid plans listed.

- CPlatforms and integrationsDesktop only: macOS, Windows and Linux. No mobile app and no integrations listed.

Keep Responsively App, or make your own?
Keep it
Responsively App is free, so making your own would save you nothing.
And it is not the kind of software a weekend replaces.
What you could not
- A web browser.
- Capture tools hooked into the operating system.
- Apps for macOS, Windows and Linux that stay in step with each other.
What this rests on. Responsively App’s listing: what it does, where it runs, what it plugs into and what it costs. It is a judgement about the kind of software this is. We have not built a replacement for it, and making your own means looking after it too. How we decide, and every tool’s verdict.
What is Responsively App?
Responsively App is a desktop browser for web developers that previews a site on many device sizes side by side, mirroring clicks, scrolls and navigation across them. It is built with Electron, is open source under the AGPL-3.0 license, and is free to download for Mac, Windows and Linux.
Worth knowing
- It is a developer tool, not a general-purpose daily browser.
- It is built on Electron, so it previews sites with Chromium rather than Safari or Firefox engines.
- It runs on Mac, Windows and Linux only, with no mobile version.
- A beta channel is offered next to the stable release.
Key features
- All devices at once
- Many device previews show side by side, so there is no need to resize the dev tools window.
- Mirrored interactions
- A click, scroll or navigation in one preview is repeated in all the others in real time.
- Preview Suites
- Favorite device combinations are saved as Preview Suites and switched between while testing.
- Device profiles
- A large collection of device profiles is built in, and custom devices can be added.
- Unified Inspector and screenshots
- One inspector covers every device, and full-page screenshots of all devices are taken in one click.
- Ordinary browser features
- Cookie, local storage and session storage management, bookmarks and the usual dev tools are included.
