All-in-one web toolkit: DNS history, reverse IP, WHOIS.

OSINT.SH lists web tools including DNS History (view all DNS historical records for a specified domain name), Reverse IP (find all A records associated with an IP address), Whois History (the historical WHOIS records of a domain name), Subdomain Finder and Certificate Search, plus a technology stack checker and a search for public buckets on AWS S3 and Azure Blob by keyword. The README says its API is limited to sponsors only. The home page credits Teguh Aprianto.

Dual-use tool. This tool can be used for research and investigation, and also to find, track or identify people without their consent. Listing it here is not an endorsement of either use.
Privacy note. OSINT.SH lists WHOIS history, reverse WHOIS and an email finder among its tools, alongside DNS history and reverse IP lookups, so records tied to a domain you registered, and email addresses its Email Finder returns, can appear in its results.
