Free Sitemap URLs Comparison

Our sitemap URLs comparison takes two sitemap URLs and produces a clear diff between the page URLs each one lists. Enter the two sitemaps and the tool fetches both on our server, follows any sitemap indexes into their child sitemaps, flattens each side into a deduplicated URL list, and compares them. You get three buckets: added (in sitemap B but not in A), removed (in A but not in B), and unchanged (in both).

The added and removed lists are previewed on screen so you can scan the most actionable URLs right away. The full diff, including the unchanged set, is available as a streaming download in TXT, CSV, or JSON. The comparison runs against the live sitemaps, so it reflects what each site is publishing right now, not a stale snapshot.

For SEOs

Our tool gives you the exact URL delta in one step, so you can:

• Audit a site migration to confirm no URLs were silently dropped
• Track week-over-week changes on a competitor's published pages
• Diff a staging sitemap against production before launch

For Developers

Our tool saves you writing two parsers and a set comparison, so you can:

• Spot URL drift between two environments without scripting
• Export a CSV of added or removed URLs for a redirect map
• Feed the JSON into a CI check or a status page

Why Use Our Sitemap URLs Comparison

• Follows sitemap indexes on both sides: It recurses into child sitemaps before the diff, so you compare the full URL set on each side, not just the index files.
• Download the full diff: Get every added, removed, and unchanged URL as TXT, CSV, or JSON, ready for a spreadsheet, a redirect builder, or a script.
• Honest and clear: Counts, an overlap percentage, and clear labels if either side hits the per-sitemap cap, so you always know how complete the comparison is.
