What Devin does
Devin, Cognition's AI software engineer, browsing the web while it works on a task.
As an autonomous agent, it uses a website like a person would, clicking, typing and filling in forms to finish a task for someone. The kinds of AI agent that visit websites.
Should you allow it?
Make your journeys work for it. Many browser agents look like an ordinary browser, so you can't reliably block them by name; test whether they can finish your key tasks instead. A decision guide for blocking or allowing AI crawlers.
How to allow or block Devin
Devin reads the Devin group in your robots.txt. To block it everywhere:
User-agent: Devin
Disallow: /To allow it everywhere, even if another rule blocks other bots:
User-agent: Devin
Allow: /Robots.txt is a request, not a lock: well-behaved crawlers follow it, impostors don't. Robots.txt for AI agents.
How to tell if it's really Devin
Our registry doesn't verify Devin against published IP ranges yet, so treat a request that uses the name as a claim, not proof: anyone can send its user agent. Check Cognition's documentation for how to verify it.
Does Devin visit your site? Ghost Agent Lab reads your CDN or server logs and shows every request from Devin and 1,566+ other known agents: what they read, what your site sent back, and whether each request was genuine. See agent traffic, or check whether AI agents can use your site for free.
