PageTwin — Visual website comparisons

See what changed before your client does. Capture, compare, annotate, and export locally.

Capture a website before an update, capture it again afterwards, and review what changed. PageTwin captures full pages by scrolling and stitching screenshots on your device. Compare before and after side by side, drag a comparison slider, or inspect outlined change regions on the updated page. Added and removed page sections are compared without stretching the screenshots. • Full-page capture, with a visible-area option • Saved baselines and local projects • Before, After, Side by side, Slider, and Difference views • Sensitivity adjustment and ignored regions • Review notes and reviewed status • HTML reports and JSON backups Screenshots, URLs and notes remain in your browser. No account, analytics or cloud screenshot service is required. Exports stay under your control. Keep the popup open while capturing. Match the browser window size and zoom between captures. Full-page capture supports vertically scrolling documents up to 32 megapixels, 32,767 physical pixels tall and 60 sections. It does not expand nested scrolling panels, virtualized feeds or frames. Pages with horizontal overflow or layouts that keep changing may require the visible-area option. Visual differences are not automatic defect diagnoses. Support: arslan8122@gmail.com
