Check a crawler's identity

Paste the IP and User-Agent recorded by your site. The checker uses current verification data, so an old detection can differ when an operator's ranges or DNS records change.

Paste the User-Agent value from your log. The claim is what gets checked.

Verified means authoritative evidence supports the claim. Forged means authoritative evidence contradicts it. Cannot tell means there is not enough evidence. An unrecognized User-Agent has no known crawler identity to check.
