Visual parity workspace
Parity Scrollr
Parity Scrollr is a Chrome and Edge extension for comparing a reference site and replica in synchronized browser panes. It keeps layout differences visible while giving frontend QA one place to control responsive viewports, navigation, and captures.
What I’m exploring
- Keep viewport scrolling pixel-locked and synchronize matching independently scrolling elements.
- Use optional URL parity, Blink mode, and shared responsive presets or custom viewport dimensions.
- Capture the visible comparison or stitch a full-page PNG while restoring the original scroll positions afterward.
