crt.sh

crt.sh searches public certificate transparency logs, one of the fastest ways to discover subdomains an organisation has issued certificates for. Because every publicly trusted certificate is logged, it reveals hosts that never appear in normal DNS enumeration. It is free, fast and a standard part of subdomain discovery.

Wayback Machine (Internet Archive)

The Wayback Machine, run by the Internet Archive, stores historical snapshots of web pages, making it essential for recovering deleted, altered or defunct online content. Researchers use it to prove how a page looked at a given moment and to retrieve information taken offline. The service is free and holds hundreds of billions of captures.
