Compare testing and production in two tiled Chrome windows with synchronized navigation and scrolling.

Environment Compare helps developers, testers, and product teams compare testing and production websites side by side. Enter the complete URLs for both environments, and the extension opens them in two automatically tiled Chrome windows. Navigation from testing is mirrored to production while preserving the path, query parameters, and URL fragment. Key features: Automatically tiled testing and production windows Testing-to-production URL synchronization Smart or percentage-based scroll synchronization Full-page and visible-area screenshots Overlay, difference, and blink comparison modes Pixel mismatch percentage Previous and next change-region navigation Dynamic-content masking for timestamps, ads, banners, and personalized content Exportable ZIP reports with an HTML summary and separate PNG images Production protection that blocks accidental clicks, typing, and form submissions Saved comparison presets Captures and reports are processed locally in Chrome.
