What it does

CloudflareBrowserRenderingCrawler is a web crawler operated by Cloudflare that returns rendered website content for research, monitoring, and AI data workflows.

ai.robots.txt describes its function as: AI Data Providers

Source: ai.robots.txt.

How to block or allow CloudflareBrowserRenderingCrawler

Add a group for its token to the robots.txt file at the root of your site. To keep it out of the whole site:

User-agent: CloudflareBrowserRenderingCrawler
Disallow: /

To let it crawl everything, use an empty Disallow: or Allow: / instead. WordPress serves a virtual robots.txt that many SEO plugins let you edit. A real robots.txt file uploaded to the site root takes its place.

robots.txt is a request, so it only works on crawlers that honour it. A bot that ignores it has to be blocked at the server or firewall, by user agent or IP address.

How Vireo counts CloudflareBrowserRenderingCrawler

When a request's user agent contains CloudflareBrowserRenderingCrawler, Vireo keeps it out of your pageviews and visitors and counts them on its bot report under Other bots, so you can see how much it left out rather than wonder why your server logs show more traffic.

Checked by running Vireo Analytics' own bot filter over the bot's name.
