Username & Social Media Tracking
Blackbird
Fast username and email search across 600+ platforms.
Blackbird is an open-source command-line utility designed to search for specific usernames and email addresses across more than 600 online platforms. It helps researchers and investigators identify digital footprints by checking if a given identifier is active on various social media sites and services. This tool is typically used in OSINT workflows to map out an individual's online presence and associated accounts.
Dual-use tool. This is capable of legitimate research (journalism, security, due diligence) and of harassment or stalking. Listing it here is not an endorsement of either use.
Privacy note. Reusing one username lets tools like this link all of your accounts together.
