maigret

Maigret is an open-source OSINT tool that collects a dossier on a person using only a username. It checks for accounts across a large database of sites and gathers available information from profile pages and site APIs, without requiring API keys. Key capabilities described in the README: - Coverage of 3,000+ sites, with a default run checking the 500 highest-traffic sites; `-a` scans everything and `--tags` narrows by category or country. - Extraction of account-owner information from profile pages and site APIs, including links to other accounts, via the socid_extractor project. - Recursive search using discovered usernames and other identifiers. - Filtering by tags such as site category or country. - Detection and partial bypass of blocks, censorship and CAPTCHA; optional Cloudflare bypass through a local FlareSolverr instance (marked experimental). - Auto-updated site database fetched from GitHub once per 24 hours, with a built-in fallback when offline. - Support for Tor and I2P sites and domain checks, plus generic HTTP/SOCKS proxy routing. - A built-in web interface for browsing results as a graph and downloading reports. - Optional AI analysis mode (`--ai`) that sends findings to an OpenAI-compatible chat completion endpoint to produce a short investigation summary; the endpoint and model are configurable. Installation options include pip, a standalone Windows executable, Snap for Linux, Docker images (CLI and web variants), and cloud shells such as Google Cloud Shell, Replit, Colab and Binder. A community Telegram bot is also mentioned for users who prefer not to install anything. Output formats include HTML, PDF (optional extra), XMind, JSON (simple and ndjson), CSV, TXT, an interactive D3 graph, and a Neo4j Cypher script for graph-database import. The tool can also be embedded in Python projects as a library. Useful CLI flags noted in the README include `--parse` for extracting IDs from a profile URL, `--permute` for generating username variants, `--self-check` for maintainers auditing the site database, and `--ai`/`--ai-model` for the analysis mode. The project is MIT-licensed and free for commercial use, with a separate commercial offering for a daily-updated private site database and a username-check API. The README includes a disclaimer that the tool is intended for educational and lawful purposes, and that users are responsible for complying with applicable laws such as GDPR and CCPA.
