Lamina

Stop eyeballing the last pixels in your design.

Lamina lays your design over the live interface as a transparent sheet — so you fix the drift in the build instead of guessing at it in a second window.

Designed for visual precision.

Overlay & Align

Place images, resize freely, adjust opacity, and move every overlay precisely, one pixel at a time.

Inspect

Pick colors with the pixel magnifier and read exact values quickly, clearly, and without any guesswork.

Compare

Crossfade, split, or amplify differences to reveal every visual change clearly and immediately across both images.

Measure & Guide

Add lines, shapes, and guides, measure true image pixels, and snap every element neatly into place.

Annotate

Add numbered markers, write notes, or blur sensitive areas permanently into every exported image you share.

Work Through It

Lock the overlay click-through, keep building underneath, and leave the reference exactly where it belongs onscreen.

Find Gaps

Point into any gap, and Lamina finds both edges, measures the distance, and skips manual dragging.

Grid

Add a grid from 10 to 5000 pixels; labels fade when crowded and return when zoomed closer.

Stay in Place

Keep the overlay above everything, on every Space, out of your way. It waits in the menu bar until you need it.

Export

Save your work with every annotation as a PNG and preserve the image’s original resolution exactly.

You can try the core features directly here on the website. The demo uses a sample image and is intentionally limited. In the full desktop app, you can load your own images, compare and annotate them, work with the complete toolset, and save or export your results.

Work straight through it.

Lock the overlay click-through and keep building underneath. The reference stays exactly where it belongs while you adjust the real interface below it.

You hand over proof, not opinions.

Blend, slide or diff two states — identical pixels turn black, deviations light up. Then export a full-resolution PNG with the measurements burnt in, or send it straight to the clipboard.
