User Scanner
Email and username lookup across thousands of sites for OSINT work
What it is
A command-line OSINT tool that checks whether an email address or username is registered on more than 2,700 websites and pulls public profile details such as avatars, bios, and follower counts. It can pivot from found profiles to linked handles and emails, generate username variations, query infostealer breach logs, rotate proxies, and export results to PDF, JSON, or CSV. Security researchers and investigators use it to map a person's online footprint, and an optional MCP server lets AI agents run the same scans.
