Unlimited overlay layers
Stack every screen, state and breakpoint on one page. No two-layer cap, no upgrade prompt.
Design overlay for Chrome, Edge and Firefox
Pixel-perfect frontend work, free.
Drop a design mockup on top of any live page and compare your build pixel by pixel. Unlimited layers, every blend mode, and your setup restored per site.
Install it where you build
One extension, three browsers. Listings go live with the public release.
Made for the last 4 pixels
The gap between a design and a build is small and stubborn. These are the tools that close it.
Every blend mode
Normal, invert, difference, multiply and overlay. Difference turns a matched pixel to black, so drift is impossible to miss.
Per-site auto-restore
Your layers, opacity and position come back exactly as you left them the next time you open the site.
Click through locked overlays
Lock a layer and the page underneath stays fully clickable, so you keep building while you compare.
Fixed or absolute positioning
Pin the overlay to the viewport or anchor it to the document for long, scrolling pages.
Stays on your machine
No account, no telemetry, nothing leaves the browser. Dark mode and English or Russian, built in.
Everything unlocked, nothing to upgrade
The premium overlay features other tools reserve for a paid tier ship here for free.
