Checked 5 November 2026 against Screaming Frog SEO Spider's public documentation. “Not listed” means we did not find it documented, not that it cannot be done. Something out of date? Write to support@perfbee.com and we fix it. Product names belong to their owners.
PerfBee crawls from its own servers as PerfBeeBot: a named user agent, one published IP address and signed requests. When a firewall still blocks a page, it is marked not checked instead of broken, and it is not billed.
Site Pages keeps every URL your crawls of a site found in one list, with its status, indexability and issues. Filter by folder, see the pages that went missing, and open any page for its details.
robots.txt is checked for 14 AI bots one by one, pages that AI answers cannot quote are listed, and you hear when an AI search bot that could reach your site no longer can. On every plan, with no extra credits.
Screaming Frog suits you if you want a desktop crawler you install and run on your own computer.
