Compare two XML sitemaps or URL inventories. Find added, removed and changed URLs, inspect directory totals and download the evidence locally.
Files and pasted content are processed locally, never uploaded or saved. Closing or refreshing clears them. Usage events contain the tool name and action only.
Save the old and new sitemap files, or export their URL inventories. Upload one input on each side.
For a domain or staging migration, optionally map one exact origin to another. Other URL distinctions remain intact.
Review removed URLs first, then new URLs and lastmod changes. Export a release record for your team.
The result tables preserve the observations behind each finding. Filter rows to focus your review, add notes to the main table and export a CSV. Use the text report to keep the method and limitations alongside the data.
A local diagnostic answers a bounded question about the input you provide. It does not prove how a search engine crawled, indexed or ranked your site. Follow up with a live check or the relevant first-party report when the decision depends on that evidence.
No. The tool processes the input in this browser tab. It does not upload, save or fetch the supplied URLs. Closing or refreshing clears your input. Basic tool-name/action events never include file contents, filenames, URLs or queries.
Yes. Load the worked example and run the check to see a clearly fictional input and its output. Replace the sample with your own data before making decisions.
No URLs are fetched and child sitemap files are not followed. Sitemap removal does not prove deletion or deindexing. Maximum 2 MB and 20,000 URLs per input.
Yes. Download every result table as CSV or save a text report with method notes. Reviewer notes appear in the corresponding table CSV. Exports escape formula-like cell values for safer spreadsheet use.
