Know when your sitemap changes.
SitemapDiff checks your sitemap every day and emails you when URLs are added or removed.
No crawling. No SEO dashboard. Just sitemap changes.

How it works
One quiet daily check.
Add your sitemap
Enter an XML sitemap or sitemap index. We fetch and validate it immediately.
We compare it
Every day we compare URL presence against the last successful snapshot.
Get notified
If URLs appear, disappear, or a check fails, you get a clear email.
What the change data can power
One simple signal. Many possible workflows.
SitemapDiff tells you which URLs were added or removed. That factual change data can become the starting point for workflows you build with your own tools.
Examples, not included features
SitemapDiff does not generate content, scrape prices, update your CRM, or run AI agents. The examples below are potential ways to use SitemapDiff data in separate workflows and services.
Your own and client websites
Protect releases, watch migrations, and feed your existing publishing or automation stack.

Compare URLs before and after a migration to find missing pages.

Use a newly detected blog post to start your social-draft workflow.
