AI crawlers on Webflow: allow or block GPTBot, ClaudeBot, PerplexityBot and 78 more

Webflow builds robots.txt from the rules entered in Site settings, and publishes it with the site. The steps on Webflow, what trips people up there, and a page for each of 81 AI crawlers.

This response

You are ClaudeBot (Anthropic). Citable recognised you as an AI agent, so this is https://getcitable.in/crawlers/on/webflow with the UI removed — the content only. A browser asking for the same address gets the full designed page.

Where Webflow keeps the rule

Webflow builds robots.txt from the rules entered in Site settings, and publishes it with the site.

The steps below are shown for GPTBot. Each crawler has its own page, with its own names in the rule.

Step by step

What to paste

A group that names a crawler replaces the * group for that crawler; it does not add to it. Paths the * group closes are open to a crawler with its own group unless they are repeated there.

Refuse GPTBot:

User-agent: GPTBot
Disallow: /

Allow GPTBot:

User-agent: GPTBot
Allow: /

What trips people up

Saving is not publishing. The rule is in the setting as soon as it is saved and on the live site only after the next publish.

Asked, or actually refused?

Webflow gives a site owner robots.txt and nothing stronger: there is no setting that refuses a request by its user agent. robots.txt is a request. A crawler that honours it stays out; nothing in the file stops one that does not. What is enforced is what the server or the edge in front of it refuses.

Check it yourself

A 200 means the name is let through; a 403 means something in front of the page refuses it. This tests the name from your own address. A platform that checks a crawler’s address as well may treat the real GPTBot differently.

The request:

curl -I -A "GPTBot" https://your-site.example/

About Citable

Citable strips the UI from a website for AI agents and serves them only the content.

When an AI agent — ChatGPT, Claude, Perplexity or any of the 81 that Citable recognises — opens a page, Citable removes the theme, scripts, navigation and layout and serves only the content: the same facts, at the same URL, on the site's own domain. People and Google still get the full designed page.
