Responsive Website Test

A responsive website test shows whether your layout works on a phone, a tablet, and a desktop. Paste a public URL to preview it at mobile 375px, tablet 768px, and desktop 1280px, side by side. Then click a breakpoint to leave a comment, so the note stays attached to the screen size you were looking at.

How do I test a website on mobile, tablet, and desktop?

Paste the page URL and choose Preview Breakpoints. Miru loads the same page at 375px, 768px, and 1280px, each 900px tall, so you can compare the three layouts on one screen.

What screen sizes does this responsive test use?

Mobile is 375 pixels wide, tablet is 768, and desktop is 1280. Each preview is 900 pixels tall and shown at its real size.

Can I leave feedback on a breakpoint?

Yes. Hover a preview, click where the issue is, and write a comment. Sending the comment asks you to create a Miru account so the feedback can be shared with the people who will fix it.
