Changelog
- May 9, 2026description
A lightweight developer tool that displays a floating overlay with real-time viewport dimensions, browser window size, and Tailwind CSS breakpoint detection on any webpage. Features: - Shows viewport dimensions (width × height) updated in real-time as you resize - Shows browser window size via Chrome's native API - Automatically detects Tailwind CSS breakpoints (v3 and v4) and displays the current active breakpoint - Draggable overlay that snaps to the nearest corner - Toggle visibility of each measurement independently - Configurable default position (any corner) - Settings persist across sessions - Minimal permissions: only runs when you click the extension icon - Zero impact on page performance — uses Shadow DOM for complete CSS isolation
