opencode
opencode is a bot operated by opencode (open source) that pulls documentation and examples while an AI writes code. OpenCode is an open-source AI coding agent that helps developers write code from the terminal, IDE, or desktop, supporting multiple LLM providers and local models. No IP range list or reverse-DNS convention is published, so a request carrying this user agent cannot be proven genuine and a robots.txt rule alone will not stop a forgery.

Allow or block opencode
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.
User-agent: opencode
Disallow: /Blocks every path for this crawler only.
User-agent: opencode
Allow: /Explicit allow. Useful when a wildcard rule above it would otherwise catch this crawler.
User-agent: opencode
Allow: /
Disallow: /account/
Disallow: /checkout/
Disallow: /searchEdit the Disallow paths to match your own account, checkout and search URLs.
What blocking actually costs you
Blocking opencode mainly affects developers reading your documentation through an AI tool. Most sites want that traffic.

A user-agent header is a string the client chooses. Scrapers copy opencode 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.

Agentscan checks a request against published crawler ranges, reverse DNS and hosting data, then returns a verdict your edge can act on. One call per request, no range files to keep up to date.
