Sitemapper
Website change intelligence for production safety
Sitemapper watches production websites and compares each trusted crawl with the last. It surfaces changes to sitemap inventory, indexability, HTTP status, canonicals, robots access, and critical journeys—then explains why a change matters and what to check next. A free public survey works without signup; monitoring, incident history, alerts, CI guardrails, API access, and Search Console support are available in the app. Built around preserved evidence, not invented impact.
Top comment
Websites change constantly, and the dangerous changes are the ones that look normal on the surface. We built Sitemapper after seeing how easily a sitemap, canonical, robots rule, or critical page can shift unnoticed after a deploy. The strongest proof came from our own production monitoring: Sitemapper recorded accessible sitemap inventory changing from 1,361 URLs to 0, preserved the before/after evidence, and later recorded 1,361 URLs again. That observation does not prove traffic loss or origin-side deletion, so the product keeps the claim bounded: it shows exactly what it saw, why the change could matter, and what to investigate. We would love feedback from teams responsible for production sites.
