About this bot
Anchor Browser is a signed browser-agent platform used for agentic web browsing.
Anchor signs outbound agent traffic with HTTP Message Signatures for Web Bot Auth, allowing websites to validate a cryptographic agent identity through its published key directory. The Anchor Browser User-Agent can still be used as a secondary classification signal.
Directory status: Active. Identity classification: Verified with High confidence.
robots.txt behavior is currently unconfirmed at the platform-identity level.
