See your app on every screen size at once

Yey. I made Tessera because resizing DevTools and hoping I caught every breakpoint was wasting my time.

You get a canvas of live browser tiles at real device sizes. Click around inside them. Turn on Follow so they scroll together.

Pro can zip DPR screenshots of the whole wall, or you can send someone a share link to your exact layout.
