Best tool for crawling a site for broken outbounding links?

Hi,

which tool can you recommend for crawling broken outbounding / external links on a site? Goal is to find expired domains.

A cheap tool would be also great

Screaming Frog would probably be the entry-level app. You can play around with the free version as it may be enough for your needs. There's an old thread here which may also have some other options: https://www.blackhatworld.com/seo/1...-can-use-today-for-more-traffic-2018.1022007/
