Web page element measurement tool using ruler overlay and element selection mode

Enables web developers, designers, and marketers to quickly measure pixel dimensions, positions, and spacing of elements on web pages for design accuracy and layout verification

1. User installs extension and presses Alt+P or clicks browser action icon 2. Content script injects measurement toolbar overlay into current webpage 3. User can switch between ruler mode (draw measurement rectangles) and element mode (hover to highlight DOM elements) 4. Element mode shows Width, Height, Left, Right, Top, Bottom values for selected elements 5. User can dock toolbar to top or bottom of page, toggle guides, and customize ruler color 6. Measurements persist until user closes the extension on that tab

Target users: Web developers / UI/UX designers / Front-end engineers / Digital marketers / QA testers

Source code is heavily minified/bundled making direct code analysis difficult
Google Analytics tracking (G-RNKZ4M80C1) is embedded but doesn't affect core functionality
No payment integration or login system found - this is a straightforward measurement utility

Monetization

No paid features detected

All features described in the store listing and implemented in the code are free. The 'pro' keyword matches in the source are false positives from minified code containing UUID library variable names. The 'license' keyword is just a CSS comment referencing the open-source license URI. No payment processing, subscription logic, or feature gating exists in the extension.

Confidence: 95
Payment platform: --
Source: AI / High
Login required: No
Reason: The extension operates entirely locally within the browser. The 'session' references in the code are for Google Analytics session tracking (client ID generation), not user authentication. No login UI, authentication flow, or account creation exists in the popup.html, popup.js, or any other files.
