PixelLayer Pro: Design Overlay, 6 Free Layers & CSS Diff Checker

Overlay Figma mocks on any page with opacity, nudge, scale & CSS difference mode. 6 free layers, zero forced rotation.

Overlay a design mockup on any live web page and see exactly where the build has drifted - without screenshotting, opening an image editor, or paying a monthly subscription for a basic opacity slider. PixelLayer Pro is a design overlay and pixel diff tool for front-end developers, UI designers and QA engineers. Drop in a Figma export, Sketch artboard or PNG, set the opacity, and nudge it into place with the keyboard. WHAT YOU CAN DO - Compare a Figma or Sketch mockup against the live build, in place - Overlay a design on a live website at any opacity from 0 to 100% - Pixel diff mode: stack design and page to find 1px padding and alignment drift - Arrow-key nudging (1px, or 10px with Shift) for exact alignment - Click-through lock, so the page stays usable underneath the overlay - Up to 6 layers: desktop, tablet and mobile mockups at the same time - Per-domain position memory, so overlays stay aligned across reloads - Ruler guides and an element distance inspector (Pro) FREE FOREVER: 6 design layers, opacity, nudging and click-through lock, with no account needed. Pro adds unlimited layers, pixel diff mode and per-domain memory - 2.99 GBP per month, 19 GBP per year or 35 GBP once. Your mockups never leave your browser: no uploads, no cloud storage, no telemetry. Works on any page you can open in Chrome or Edge.
