Reported, not operator documented

ByteDance has not published a crawler page that names Trae. It is listed here on our own evidence. Verified by AI Crawler Check: 15 of the 5,583 valid robots.txt files in the Tranco top 10,000 carry a rule for Trae, so site owners treat it as a real crawler name (how we measure this). That proves the spelling is in use, not who sends it. Reported ByteDance Trae agent fetches. No vendor UA published.

What that means for you: the Trae rule on this page is the best available spelling, but ByteDance has made no statement of purpose, crawl rate or robots.txt compliance. Treat a Trae request in your logs as a clue, not proof of who sent it, and add a firewall rule if that traffic matters to you. If the operator publishes documentation, this profile moves to Official docs.

What is Trae Agent (ByteDance)?

Trae Agent (ByteDance) is an on-demand AI fetcher operated by ByteDance. It retrieves a page only when a user explicitly asks an AI assistant or agent to read, summarize, or act on a specific URL. Because it is triggered by real user intent rather than bulk crawling, blocking it mainly prevents users from pulling your content into ByteDance's assistant.

Trae Agent (ByteDance) uses the user-agent token Trae. You can control it via robots.txt, meta tags (noai), or the emerging llms.txt standard. Robots.txt is voluntary; for hard enforcement, combine it with server-level IP blocking.

What happens if you block Trae Agent (ByteDance)?

✅ No SEO Impact - Blocking Trae Agent (ByteDance) does not affect your rankings in Google, Bing, or any other search engine. Trae Agent (ByteDance) is an AI crawler, not a traditional search indexer. You can freely block it via User-agent / Disallow: / without any SEO penalty.
Generally safe to allow; provides legitimate crawling value.

Is Trae Agent (ByteDance) safe to allow?

Trae Agent (ByteDance) is rated Safe in this directory, meaning there are no credible public reports of abusive crawling under this name. It is a Reported token: ByteDance has not published documentation for it, so its purpose, crawl rate and robots.txt behaviour are not confirmed by the operator, and anyone can send the same user-agent string. Allow or block it on its stated purpose, and back the robots.txt rule with a firewall rule if the traffic matters to you.
ByteDance publishes no IP ranges or reverse-DNS pattern for Trae Agent (ByteDance), so the user-agent string cannot be verified. Rate-limit unusual volume instead of trusting the name.

What does Trae Agent (ByteDance) do?

Understanding Trae Agent (ByteDance)'s purpose helps you decide whether to allow or block it.

  • Fetches a page only when a user asks an AI assistant to read it
  • Summarizes or extracts the URL the user provided
  • Triggered by real user intent, not bulk crawling
  • Low traffic volume compared with training crawlers
  • Blocking it prevents users from pulling your content into the assistant

Trae Agent (ByteDance) in context

Trae Agent (ByteDance) is a user-triggered agent operated by ByteDance. In plain terms, it fetches a page when a person asks an assistant or app to open it. Our database files it under AI and LLM crawlers and ranks it Tier 3, mid-priority crawlers with a clear purpose but a smaller audience. 15 of the 104 AI and LLM crawlers in our database share this tier.

Its safety rating is safe and its blocking impact is low. So the decision about Trae Agent (ByteDance) rests on what you want from ByteDance, not on its behaviour. How we rate safety and impact.

How site owners treat Trae Agent (ByteDance)

In our own scan of the Tranco top 10,000 (5,583 valid robots.txt files), 15 files (0.3%) name Trae in a User-agent line. That shows site owners treat the token as a real crawler worth a rule. It does not, on its own, prove who operates it.

Does it follow robots.txt?

Trae Agent (ByteDance)'s operator does not clearly document how it treats robots.txt. Write the Trae Agent (ByteDance) rule anyway, then confirm in your logs that its requests stop.

ByteDance crawlers and close alternatives

Trae Agent (ByteDance) is one of 4 ByteDance crawlers in our database. A User-agent: Trae group controls Trae Agent (ByteDance) only; the other ByteDance tokens below need their own lines.

  • Trae: this crawler (Tier 3)
  • Bytespider: ByteDance / Toutiao Search, collects pages both for training and for search or answers (Tier 2)
  • DoubaoBot: Doubao (ByteDance), collects pages both for training and for search or answers (Tier 2)
  • TikTokSpider: TikTok Spider, collects pages to train AI models (Tier 2)

To give Trae Agent (ByteDance) the same answer as its siblings, stack User-agent: Trae with their lines above one set of rules; to treat Trae Agent (ByteDance) differently, give it its own group.

Other AI and LLM crawlers that do the same job (fetches a page when a person asks an assistant or app to open it) include ChatGPT Agent from OpenAI, ChatGPT Operator from OpenAI, ChatGPT-User from OpenAI, ChatGPT-User/2.0 from OpenAI, Claude-SearchBot from Anthropic, Claude-User from Anthropic. Deciding about Trae Agent (ByteDance) is usually a decision about the whole group, so check how your file treats these too.

We first recorded Trae on September 22, 2026. We could not find a page where ByteDance names it, so treat the token as reported rather than documented.

Which rule Trae Agent (ByteDance) actually follows

Trae Agent (ByteDance) reads exactly one group in robots.txt, the most specific one that names Trae, and never combines rules across groups. This short file shows the trap:

User-agent: *
Disallow: /private/

User-agent: Trae
Disallow: /drafts/
  1. Find the group. Trae Agent (ByteDance) looks for a group naming Trae. One exists, so it ignores User-agent: * completely.
  2. Apply only that group. It is refused /drafts/ and nothing else.
  3. The surprise. /private/ is open to Trae Agent (ByteDance), because that rule lives in the * group it no longer reads. To keep it out of both, repeat Disallow: /private/ inside its own group.
Test yourself: does a rule under User-agent: * apply to Trae Agent (ByteDance) if the file also has a User-agent: Trae group?

No. Once a group names it, Trae Agent (ByteDance) reads only that group. Put every rule you want it to follow inside its own group.

Test yourself: will blocking Trae Agent (ByteDance) remove your pages from AI answers?

Often, yes. Trae Agent (ByteDance) is a user-triggered agent, so pages it cannot fetch can drop out of the answers or results it supports.

Test yourself: is User-agent: trae the same as User-agent: Trae?

Yes. RFC 9309 makes user-agent matching case-insensitive. Paths are a different story: Disallow: /Blog/ does not block /blog/.

Should you allow Trae Agent (ByteDance)? Decide by situation

Recommended setting for Trae Agent (ByteDance) by type of site
If you are...Recommended setting
You publish content and want AI answers to cite itAllow it. Trae Agent (ByteDance) fetches pages for answers, so blocking it can remove you from them.
You license content and want to stop AI trainingBlocking it does not stop training, because Trae Agent (ByteDance) is a user-triggered agent. Block the operator's training crawler instead.
You run an online shopAllow it on product and category pages, which are the pages shoppers ask assistants about.
Your server is under load from botsRate-limit before blocking. It is rated safe in our database.

Check Trae Agent (ByteDance) on your own site

  1. Open /robots.txt on your domain and search for Trae. If it is not named, it follows User-agent: *.
  2. List the Disallow lines in the group Trae Agent (ByteDance) follows and test your key URLs against them; the longest match wins, and Allow wins a tie.
  3. Look beyond the file. A firewall or bot manager can refuse Trae Agent (ByteDance) even when robots.txt allows it, and that never shows in the file.
  4. Run our AI bot crawlability test to see how Trae Agent (ByteDance) and every other crawler we track are treated in one pass, including firewall refusals.

Common mistakes with Trae Agent (ByteDance)

The errors we see most often with Trae Agent (ByteDance) in the files and firewalls we test:

  1. Assuming a robots.txt rule will stop Trae Agent (ByteDance). User-triggered fetches act for a person, and some operators say robots.txt may not apply to them. Check the operator's statement above.
  2. Blocking Trae Agent (ByteDance) as if it were a bulk crawler. It fetches one page because a person asked; blocking it means that person's assistant cannot read your page.
  3. Counting Trae Agent (ByteDance) visits as crawl volume. Each request maps to a real user question, which makes the paths it requests a useful signal of what people ask about you.

All three hide inside a file that looks correct, so check Trae Agent (ByteDance) from outside after every change.

Spotting Trae Agent (ByteDance) in your logs

robots.txt says what Trae Agent (ByteDance) may do; your access logs show what it actually did.

Count requests

On a server with standard Nginx or Apache logs, this counts matching requests per day (adjust the log path for your host):

grep -iE "Trae" /var/log/nginx/access.log \
  | awk '{print $4}' | cut -d: -f1 | sort | uniq -c

And this shows which paths it requested most, which is the quickest way to see whether your Disallow lines are being respected:

grep -iE "Trae" /var/log/nginx/access.log \
  | awk '{print $7}' | sort | uniq -c | sort -rn | head -20

Check the requests are genuine

Anyone can send the Trae Agent (ByteDance) user-agent, so confirm the source before acting on a match:

  • Trae: we hold no published IP list, so use reverse DNS where the operator documents a hostname and treat an unverifiable Trae Agent (ByteDance) request with caution.

Frequently Asked Questions

What user-agent string does Trae Agent (ByteDance) use?
Trae Agent (ByteDance) is reported to identify itself with Trae. Evidence that the spelling is in real use comes from our own robots.txt study: 15 of the 5,583 valid robots.txt files in the Tranco top 10,000 name it (fetched October 20, 2026), not from ByteDance, which has not published crawler documentation naming it. Use it in robots.txt as the best available match, and treat a request carrying it as a clue rather than proof of who sent it.
Is Trae Agent (ByteDance) safe?
Trae Agent (ByteDance) is rated Safe in this directory, meaning there are no credible public reports of abusive crawling under this name. It is a Reported token: ByteDance has not published documentation for it, so its purpose, crawl rate and robots.txt behaviour are not confirmed by the operator, and anyone can send the same user-agent string. Allow or block it on its stated purpose, and back the robots.txt rule with a firewall rule if the traffic matters to you.
Will blocking Trae Agent (ByteDance) hurt my SEO?
✅ No SEO Impact - Blocking Trae Agent (ByteDance) does not affect your rankings in Google, Bing, or any other search engine. Trae Agent (ByteDance) is an AI crawler, not a traditional search indexer. You can freely block it via User-agent / Disallow: / without any SEO penalty.
How do I block Trae Agent (ByteDance) in robots.txt?
Add the following lines to your /robots.txt file:
User-agent: Trae
Disallow: /

This instructs Trae Agent (ByteDance) not to crawl any path on your site. To block only specific sections, replace / with the path (e.g., Disallow: /blog/).
Does Trae Agent (ByteDance) respect robots.txt?
Not documented. ByteDance has published no statement that Trae Agent (ByteDance) reads robots.txt. A rule for Trae will stop a client that chooses to honour it; for enforcement, add a firewall or CDN rule as well.
How do I verify if Trae Agent (ByteDance) is crawling my site?
Search your access logs for Trae (for example grep -i "Trae" /var/log/nginx/access.log). Because the operator publishes no IP ranges or reverse-DNS pattern, a match shows that something used the name, not that ByteDance sent it.
