  • Type: AI
  • Kind: Fetcher

Common use

AI crawling, assistant retrieval, AI search, or model-supporting discovery depending on the user-agent.

Spoofing Risk
User-agent strings can be spoofed. For allow-listing or low-friction rules, pair the published identifier with operator documentation or cryptographic verification when available.

Common Use

AI crawling, assistant retrieval, AI search, or model-supporting discovery depending on the user-agent.

Detection Notes

Match `Devin` as a case-insensitive substring in HTTP user-agent logs. Use bot_http_agent for full user-agent examples when the client sends a longer browser-like string. Do not treat a user-agent match alone as proof of identity for allow-listing.

Rules And Blocking Notes

User-agent: Devin Disallow: /

Identification Note

User-agent strings can be spoofed. Use this record as an identification signal and confirm sensitive allow or block decisions with logs, DNS, IP ranges, request behavior, or operator documentation when available.
