Catch indexation regressions early
A product page falling out of submitted-and-indexed gets flagged before the clicks vanish from your weekly report. That gives you time to fix canonicals, internal links, rendering, or crawl signals while the damage is still small.
Scale with multiple verified properties
If the same site is verified as a domain property plus relevant URL-prefix properties, Index Monitor can spread inspections across them and stretch Google’s daily limits much further.
Run it on modest hardware
This is a scheduler plus a database. Google does the crawling and indexing; your appliance only requests the answers and stores the history, so an old laptop or mini-PC is enough.
