Web developers and designers need to measure exact pixel dimensions and positions of web elements during development, layout, and design work

User can draw a rectangle to measure arbitrary areas (free selection mode) or toggle element mode to hover over and click HTML elements to see their dimensions. The toolbar displays width, height, left, right, top, bottom measurements in pixels. Users can dock the toolbar, show guides, and search element borders.

- The extension appears to be based on 'Page Ruler Redux' open source project (referenced in CSS comments)

- The extension operates entirely locally using Chrome APIs (storage, alarms, scripting). No login UI, authentication flows, account creation, or session management code was found. The keyword hits for 'auth' are false positives from CSS author comments ('Author: Esteban Rocha'). The extension can be used immediately after installation without any account.
