Public-source monitoring with boundaries

A visible crawler with clear boundaries.

Rival Spy identifies its crawler, follows source-specific policies and gives verified domain owners a self-serve opt-out path.

Collection principles

Every source type has a defined access method, request pace, fallback and customer-visible health state.

Direct page access first, rendered access only through an approved isolated route
Robots rules, page signals and verified domain-owner blocks are checked before a request
No bypass of authentication, paywalls, CAPTCHAs or technical controls
Only evidence needed to prove and classify a change is retained

Verified opt out

A domain owner can start at the crawler opt-out page, verify control through DNS or a well-known file and inspect the resulting block state. Requests are logged, and the block applies before future checks run.
