CragCrawler

CragCrawler is a bot that crawls pages into a dataset that may be reused or shared with third parties, and its operator has not been publicly identified. CragCrawler is a web scraping bot operated by CragSoftware, a Brazil-based software company specializing in data engineering and AI web scraping services. 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.

What blocking actually costs you

Blocking CragCrawler keeps your pages out of the datasets it builds from future crawls. It does not remove anything collected earlier, and how each operator uses or shares its data varies, so check their policy.

FAQ

CragCrawler questions

What is CragCrawler?

CragCrawler is a bot that crawls pages into a dataset that may be reused or shared with third parties, and its operator has not been publicly identified. CragCrawler is a web scraping bot operated by CragSoftware, a Brazil-based software company specializing in data engineering and AI web scraping services. 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.

Does CragCrawler respect robots.txt?

Not documented. No operator statement says whether CragCrawler reads robots.txt, so add the rule but verify in your logs that the requests actually stop.

How do I verify a request really came from CragCrawler?

You cannot, at least not from the request itself. 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. Compare the source IP against hosting and datacenter ranges instead, and rate limit anything that behaves like a crawler.

How do I block CragCrawler?

Add the CragCrawler token to robots.txt with Disallow: /. If the crawler ignores robots.txt, match the user agent at your CDN or reverse proxy and return 403 there instead.

Will blocking CragCrawler hurt my search rankings?

Blocking CragCrawler keeps your pages out of the datasets it builds from future crawls. It does not remove anything collected earlier, and how each operator uses or shares its data varies, so check their policy.
