Grid Overlay Pro is a professional grid overlay tool designed specifically for web development and design workflows. It brings Figma-style grids directly to any website, allowing developers and designers to verify layouts, check alignment, and ensure pixel-perfect responsive designs directly in the browser.

The extension offers customizable grid overlays where users can adjust columns, gutters, margins, and opacity to match their design specifications. It includes responsive breakpoints functionality that enables defining and testing multiple breakpoints (mobile, tablet, desktop) with automatic switching. Users can save and switch between different grid configurations using quick presets, toggle grids on/off with keyboard shortcuts (Ctrl+Shift+G), and choose grid colors that work on light and dark backgrounds.

The tool works by clicking the extension icon to activate the grid overlay on any page. Users access the full control panel via the menu button in the bottom-right corner to adjust settings, switch between presets, or configure responsive breakpoints. The overlay works seamlessly across all development environments including localhost, staging, and production sites without affecting layout or functionality.

Grid Overlay Pro helps users check grid alignment on live websites, staging environments, or local development. It's perfect for implementing design systems, debugging layout issues, and ensuring responsive breakpoints match specifications by providing visual feedback instantly.

The tool is designed for frontend developers implementing design systems, UI/UX designers verifying spacing and alignment, web developers ensuring cross-browser layout consistency, and teams maintaining visual standards across projects. It runs entirely locally in the browser with no data collection or transmission, and settings are saved locally to the user's device.
