Devin at a glance.
What to look for in your logs, and what the lookup API returns for its addresses.
- Type
- AI crawler & agent
- API flag
risk.is_ai
A user agent alone never sets a flag. Anyone can claim to be Devin; the flag follows the address the request comes from.
02 · In the response
What a match looks like.
A lookup of a Devin address sets risk.is_ai. The flags come with geolocation and network data in the same response, for API keys on every paid plan.
The response says which kind of bot an address belongs to, not which operator. A request that claims to be Devin while risk.is_ai is false should not be trusted as Devin.
{
// … location and network fields …
"risk": {
"is_ai": true,
"is_crawler": false,
"is_scanner": false
}
}
03 · Control
Allow or block Devin.
Your options
- robots.txt works only for crawlers that choose to follow it. Check the operator’s documentation for the token it reads.
- Firewall, WAF or CDN. Many offer bot rules you can allow or deny by category. Use them to enforce what robots.txt only asks for.
- In your app. Look up the client address and allow or deny on
risk.is_ai, alongside the user agent. - Never on the user agent alone. Blocking the name stops only honest clients; allowing it lets anyone in who borrows it.

About Devin.
What is Devin?
Devin is Cognition’s AI software engineer. These requests come from Devin’s hosted service when it connects to a customer’s own systems, such as a self-hosted Git server or an artifact repository.
How do I block Devin?
Deny it at your firewall, WAF or CDN, or look up each client address and deny requests where risk.is_ai is true. Do not rely on the user agent alone.
Can I trust a request that says it is Devin?
Not on the user agent alone: any client can send a bot’s name in its user agent. A user agent alone never sets a flag. Check the address with the free bot checker or the lookup API.
Which risk flag does Devin set?
Its addresses set risk.is_ai in the lookup response. The risk flags come with every paid plan.
