Compare	Screaming Frog	404 Not Found
Verdict	Worth it	Skip
Who it's not for	Non-technical marketers wanting one-click audits	Anyone right now . the product page doesn't load
Privacy	No public breaches found; the VA's federal tool registry flags one vulnerability entry for the SEO Spider.¹⁴	No known public vulnerabilities found in the sources reviewed.
Support quality	No support-quality evidence in sources	No evidence . site itself is a 404
Public sentiment	Reviewers overwhelmingly call it the go-to technical crawler, though some question the annual fee for occasional use.^¹	No user reviews of LibreCrawl exist in the sources reviewed; every result describes unrelated 404 content.
Biggest gotcha	Free version caps crawls; larger sites push you to the $279/year license fast^⁵	Domain appears dead; any payment could go to a vendor that no longer exists
