Blackbird is an 🏷️#open-source OSINT tool, created by Lucas Antoniaci, that searches for accounts tied to a given username or email across more than 600 social networks and online platforms. Written in Python, it is distributed for educational use.
Blackbird draws on the WhatsMyName data project to determine where a username or email is registered, then can generate a free AI-assisted profile summarizing behavioral and technical signals from the results. It supports filtered searches and exports findings to PDF or CSV, and emphasizes low false-positive rates. It is widely used among open-source-intelligence and security practitioners and has drawn several thousand GitHub stars.
