Grid Overlay Pro
A browser extension to visualize grid layouts on any webpage
Grid Overlay Pro is a browser extension that places adjustable grid systems over any webpage, allowing designers and developers to verify alignment and spacing. Users can set column counts, gutter widths, margins, colors, and responsive breakpoints, then store presets for future projects. The tool works locally in the browser and does not transmit data, making it suitable for checking layout accuracy and responsive behavior without leaving the page.
