One page.
Every screen.

Breakpoint Studio is a free Chrome extension that shows any website on phones, tablets, laptops and desktops side by side. Scroll, click or type on one and every device follows. Coming soon to the Chrome Web Store.

One tab, every device. Here it is testing our own homepage.

Built for checking a site before the client does.

We build and test websites every day. Breakpoint Studio is the tool we wanted: one place to see every screen, find what breaks and send the client something they can understand.

Inspect any element

Click a heading on the phone and see its font, size, colour, margin and selector. Copy the CSS, or compare that element on every device in one table.

Find where it breaks

Run the audit and each device gets a count of what is wrong: sideways scrolling, overflowing elements, small tap targets, tiny text and missing alt text.

Client-ready in one click

Every device, framed, on one image. Use it in proposals, sign-off emails and case studies, or save it as PNG, JPG, WebP, PDF or ZIP.

Mark it up, then send it

Draw arrows, boxes and notes on any capture, redact what should stay private, and move or restyle every note before you export.

Questions, answered.

Is Breakpoint Studio really free?

Yes. Every feature is free. There is no account, no premium tier, no trial and no ads.

When can I install it?

It is coming to the Chrome Web Store. Email us and we will tell you the day it goes live.

Does it collect my data?

No. It has no analytics, no tracking and no servers of its own. Settings and screenshots stay in your browser. The privacy policy lists exactly what it stores and why it needs each permission.

Why does it ask for access to all websites?

To show the website you choose inside the device frames, run the design tools inside them and capture screenshots. It only changes how a page loads inside an open Breakpoint Studio tab. Normal browsing is not affected.

Does it work with localhost and staging sites?

Yes. It works with local development servers, staging sites and local HTML files, as well as live websites.

Is it the same as a real phone?

It matches each device's screen size, pixel density and mobile browser identity, which is what most responsive bugs depend on. It still runs in Chrome, so test on real phones before launch for anything specific to Safari or a particular device.

Breakpoint Studio is a free product of CenoDigital. We design brands and build websites, online shops and custom apps for clients in Sri Lanka, the Gulf and Asia.
