Maigret
Username search across thousands of sites to build a profile dossier
What it is
Maigret takes a single username and checks for matching accounts on roughly 5,900 websites, then pulls whatever profile details it can find, including links to other accounts, and searches again on any new usernames or IDs it discovers. It needs no API keys, can filter sites by category or country, handles Tor and I2P sites, and writes reports as HTML, PDF, XMind and other formats. OSINT investigators and security researchers run it from the command line, through a bundled web interface that shows results as a graph, or as a Python library inside their own tools.
