Verified crawler identities, purposes, and policy controls

Crawler registry vs crawler registration

This page is a registry: a maintained, provider-sourced reference of documented AI crawler identities, purposes, and policy controls. It is not a registration service. OpenForBots documents known crawler identities and purposes; it does not register, authenticate, or independently certify third-party crawlers.

When a provider offers its own registration or verification process — for example, publishing IP ranges, supporting reverse-DNS confirmation, or a cryptographic signing mechanism — that process happens directly with the provider or a platform they've registered with, not with OpenForBots. See how crawler registration and verification actually work for the current documented mechanisms and their limits.
