Coding agents

Trae

Trae is a bot operated by ByteDance that pulls documentation and examples while an AI writes code. Trae is an AI-powered coding agent developed by ByteDance that can understand codebases, fetch web content, and generate code. 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.

Reference data for the Trae crawler
User agentTrae

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

PurposeCoding agents
Respects robots.txtNot documented
Verification methodNone published, user agent only

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.

robots.txt

Allow or block Trae

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 Trae
User-agent: Trae
Disallow: /

Blocks every path for this crawler only.

Allow Trae
User-agent: Trae
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: Trae
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 Trae 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 Trae?

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