New agents

Two public lists are diffed daily: the ai.robots.txt catalogue of AI crawler user agents, and the registry of agents that sign their requests with Web Bot Auth. Anything that appears for the first time is recorded here with the date we first saw it.

When each token now on the ai.robots.txt list first appeared in the list's git history. The list records when maintainers noticed a crawler, which lags launches by weeks; the March 2024 bar is the list's own start. Security teams read this as the number of new bot identities needing rules each month.

Signing-registry entries

about Web Bot Auth ↗

These registry entries advertise signing keys. Membership does not establish the identity of a visitor here. Signature-header presence is recorded without cryptographic verification.
