I made a tool to catch the boring SEO stuff that breaks after a deploy
I built Sitemapper after getting tired of checking a sitemap, then checking pages, then checking robots, then trying to remember what changed after the last deploy.
It does that in one pass. Give it a public site and it reads robots.txt, discovers XML sitemaps, checks live pages, and keeps a snapshot so later runs can tell you what actually changed.
The part I care about most is not an SEO score. It is catching boring regressions like a page turning noindex, a canonical moving, a URL disappearing, or the sitemap suddenly shrinking.

If you try it on something weird or messy, I would like to know where it falls over.
