Open Source Intelligence ( OSINT ) is the collection and analysis of data gathered from open sources to produce actionable intelligence.

This carefully edited OSINT list won't be an endless list of links, but priority will be given to highly effective content (quality over quantity) and only services that can be used for free. While OSINT itself is not illegal, it is crucial to understand that the legality of specific OSINT activities heavily depends on how the information is obtained and used.
