Skiptracer is an OSINT scraping framework that utizes basic python webscraping of PII paywall sites to compile information (passively) on a target. This is especially useful if you are operating on a very small budget.
It’s primarily US-focused, but you can use tools like LittleBrother for possible access to the EU domain.
For email search, Skiptracer checks LinkedIn, HaveIBeenPwned, MySpace, and AdvancedBackgroundChecks. For name search, Skiptracer leverages Truth Finder, True People, and AdvancedBackgroundChecks. For phone numbers, Skiptracer searches TruePeopleSearch, WhoCalld, 411, and AdvancedBackgroundChecks. For screen names, SkipTracer checks Knowem, NameChk, and Tinder. For license plates, it uses Plate Search. For domains, is uses Subdomain Search.
While there are tools that do many of these tasks better, in my opinion, there are no tools I’m aware of that do all these tasks in one place. It’s sort of a Swiss army knife of people search tools that’s an excellent place to start your investigation.
