kunugi SERP Cache

Manually cache Google's top 10 SERP and compare ranking changes between dates.

A Chrome extension that manually caches top-ranking pages from Google search results and lets you compare them side by side with previously saved snapshots. *Note: Depending on your environment, during installation Chrome may display a warning such as "This extension can change and access features like location, camera, and cookies." This is because the extension includes a feature that toggles JavaScript on and off in the browser, allowing a quick check of whether a page contains client-side rendered elements that generative-AI crawlers struggle with. Everything runs locally - no data is transmitted, and no cookies or location data are collected. [Features] With a single click of the button in the side panel, the extension saves the top 10 currently displayed Google search results. Four fields are recorded for each result: rank, URL, page title, and meta description. Saved data is automatically organized into folders by query (search keyword). Select multiple saves with the same query but different dates, and you can compare ranking changes in a single table. The comparison screen offers two view modes. The first is a ranking view that lines up the ranks from each date side by side. The second is a matrix view that aggregates every URL that appeared across the saves and shows its appearance count along with the rank from each date. The tracked domain feature lets you register domains of interest; whenever a saved result's URL matches one of them, the entry is highlighted. The comparison table can also be copied to Excel, and tracked domains are automatically flagged. You can also leave free-form notes in the memo field. All data is stored in the browser's local storage; nothing is sent to external servers. [About the warning shown in the extensions page] As of March 11, 2026, Chrome's extensions page may display the following notice: "This extension isn't trusted by Enhanced Safe Browsing." This does not indicate any issue with the extension itself. It is an automatic notice shown when a developer account is still relatively new. Google's Chrome Help article about installs through Enhanced Safe Browsing also states the following: "For new developers, it typically takes a few months before they are considered trusted. Our goal is eventually to grant this status to every developer who builds extensions while complying with the Developer Program Policies." This extension is safe to use; please install with confidence.
