Description
Align, compare, and review two chosen websites with local-first QA workflows. PairPane is a browser comparison workspace that helps you review two related web pages side by side without repeatedly switching tabs or losing your place. Pair a staging and production page, a source and translated page, or two versions of documentation. When you scroll one page, PairPane keeps the other aligned, making differences easier to find and review. With PairPane, you can: Synchronize scrolling between two tabs or windows. Keep pages aligned even when their lengths differ. Compare staging and production websites. Identify content, layout, and metadata differences. Capture evidence and add review notes. Track review results and export a clear report. Save environment pairs for recurring comparisons. Why install PairPane? Manual website comparison is slow and frustrating. You scroll one page, switch tabs, search for the same section, and repeat the process for every difference. PairPane turns that workflow into one organized comparison experience, helping QA testers, developers, content editors, translators, and technical writers review pages faster and with fewer mistakes. PairPane is designed to be privacy-conscious and local-first. It works only on pages you explicitly select, requires no account, and processes comparison information directly in your browser. Two pages. One comparison workspace.
