GitHub hosts a massive curated index of Open-Source Intelligence (OSINT) tools — publicly available software used to investigate digital identities, networks, and online activity. The OSINT tools topic page functions as a live directory linking to hundreds of investigative utilities maintained by researchers, journalists, and security analysts around the world.
OSINT is the practice of gathering intelligence using publicly accessible information. Unlike hacking, it relies entirely on legal data sources such as social media activity, domain registrations, archived websites, public records, leaked datasets, and metadata.
The GitHub directory acts as a launchpad into modern investigative research. It includes tools that can help users:
• identify social media accounts connected to a person
• analyze usernames across platforms
• investigate email addresses and digital footprints
• map relationships between individuals and organizations
• locate archived or deleted webpages
• analyze websites, domains, and hosting networks
• track bot networks and coordinated propaganda campaigns
Researchers, journalists, and citizen investigators frequently rely on OSINT to uncover fraud, trafficking networks, financial corruption, extremist organizing, and influence operations. Many major investigative stories in recent years have relied entirely on open-source analysis.
Because the tools are community-developed, the directory continuously grows and updates as new investigative methods emerge.
