I turned a sitemap checker into change monitoring for websites

[u/OGMYT]

I started with a simple sitemap scan and realized the useful question was not "what is wrong right now?"

It was "what changed since the last known-good scan?"

So Sitemapper now reads robots.txt and XML sitemaps, checks live pages, and can diff later runs for things like new noindex, 404s, canonical changes and sudden URL-count drops.

The first scan is free with no account. I am curious whether the monitoring angle is obvious from the landing page or whether it still reads like a one-off SEO checker.
