Devin

Devin is a bot operated by Devin AI that pulls documentation and examples while an AI writes code. Devin is a software engineering AI assistant that can browse websites and perform web-based tasks, functioning as a collaborative AI teammate for engineering teams. It is documented as honouring robots.txt, but no IP range list or reverse-DNS convention is published, so a request carrying this user agent cannot be proven genuine.

Token only. The operator has not published a full user-agent string, so match on the substring rather than an exact header.

robots.txt

Allow or block Devin

Paste one of these into the robots.txt file at the root of your domain. Rules are per token, so a block on one crawler leaves every other bot untouched.

Block Devin
User-agent: Devin
Disallow: /

Blocks every path for this crawler only.

Allow Devin
User-agent: Devin
Allow: /

Explicit allow. Useful when a wildcard rule above it would otherwise catch this crawler.

Allow, except the pages you never want quoted
User-agent: Devin
Allow: /
Disallow: /account/
Disallow: /checkout/
Disallow: /search

Edit the Disallow paths to match your own account, checkout and search URLs.

What blocking actually costs you

Blocking Devin mainly affects developers reading your documentation through an AI tool. Most sites want that traffic.

Block every crawler in the directory at once
Verification

Is that really Devin?

A user-agent header is a string the client chooses. Scrapers copy Devin precisely because site owners allow it. No IP range file and no reverse-DNS convention have been published for this agent. The user-agent string is the only signal, and any client can send it, so treat a match as a claim rather than proof.

Paste the IP address from your access log below. You will see whether it belongs to a hosting provider, a residential proxy pool or a Tor exit, plus the ASN that announces it, which is what tells you whether the claim holds up.
