Contents In one minute Main features Demo Installation Usage Contributing Commercial Use About In one minute Ensure you have Python 3.10 or higher. pip install maigret maigret YOUR_USERNAME No install? Try the community Telegram bot or a Cloud Shell . Want a web UI? See how to launch it . See also: Quick start . Main features Supports 3,000+ sites ( see full list ). A default run checks the 500 highest-ranked sites by traffic; pass -a to scan everything, or --tags to narrow by category/country. Embeddable in Python projects — import maigret and run searches programmatically (see library usage ). Extracts all available information about the account owner from profile pages and site APIs, including links to other accounts. Performs recursive search using discovered usernames and other IDs. Allows filtering by tags (site categories, countries). Detects and partially bypasses blocks, censorship, and CAPTCHA. Fetches an auto-updated site database from GitHub each run (once per 24 hours), and falls back to the built-in database if offline. Works with Tor and I2P websites; able to check domains. Ships with a web interface for browsing results as a graph and downloading reports in every format from a single page. Optional AI analysis mode ( --ai ) that turns raw findings into a short investigation summary using an OpenAI-compatible API. For the complete feature list, see the features documentation .

Cloud Shells Run Maigret in the browser via cloud shells or Jupyter notebooks: Local installation (pip) # install from pypi pip3 install maigret # usage maigret username From source # or clone and install manually git clone https://github.com/soxoj/maigret && cd maigret # build and install pip3 install . # usage maigret username Docker Two image variants are published: soxoj/maigret:latest — CLI mode (default) soxoj/maigret:web — auto-launches the web interface # official image (CLI) docker pull soxoj/maigret # CLI usage docker run -v /mydir:/app/reports soxoj/maigret:latest username --html # Web UI (open http://localhost:5000) docker run -p 5000:5000 soxoj/maigret:web # Web UI on a custom port docker run -e PORT=8080 -p 8080:8080 soxoj/maigret:web # manual build docker build -t maigret . # CLI image (default target) docker build --target web -t maigret-web . # Web UI image Troubleshooting Build errors? See the troubleshooting guide . PDF reports ( --pdf ) are an optional extra — install with pip install 'maigret[pdf]' . They need system-level graphics libraries on Linux/macOS; see the PDF reports section for per-OS install steps. Usage Examples # make HTML, PDF, and XMind reports maigret user --html maigret user --pdf maigret user --xmind # legacy XML with a manifest for XMind 2022+ readers # machine-readable exports maigret user --json ndjson # newline-delimited JSON (also: --json simple) maigret user --csv maigret user --txt maigret user --graph # interactive D3 graph (HTML) maigret user --neo4j # Neo4j Cypher script (graph database) # search on sites marked with tags photo & dating maigret user --tags photo,dating # search on sites marked with tag us maigret user --tags us # highlight sites whose page also mentions specific keywords maigret user --keywords python rust # keyword-matched sites are shown with "[++]" in bright green # search for three usernames on all available sites maigret user1 user2 user3 -a # AI-assisted investigation summary (needs OPENAI_API_KEY) maigret user --ai --neo4j writes a *_neo4j.cypher script of the results graph; import it with cypher-shell -u neo4j -p <password> < report_user_neo4j.cypher or paste it into the Neo4j Browser. Re-imports are idempotent. See the Neo4j export docs . Run maigret --help for all options. Docs: CLI options , more examples . Running into 403s or timeouts? See TROUBLESHOOTING.md . Web interface Maigret has a built-in web UI with a results graph and downloadable reports. Don't want to run it yourself? Deploy the published soxoj/maigret:web Docker image as a hosted app in one click: Runs on Render's free tier (spins down after 15 min idle, spins back up on the next request). No login is set up on the instance, so anyone with the URL can use it. Web Interface Screenshots maigret --web 5000 Open http://127.0.0.1:5000 , enter a username, and view results. Python library Maigret can be embedded in your own Python projects. The CLI is a thin wrapper around an async function you can call directly — build custom pipelines, feed results into your own tooling, or run it inside a larger OSINT workflow. See the full library usage guide for a working example, async patterns, and how to filter sites by tag. Useful CLI flags --parse URL — parse a profile page, extract IDs/usernames, and use them to kick off a recursive search. --permute — generate likely username variants from two or more inputs (e.g. john doe → johndoe , j.doe , …) and search for all of them. --self-check [--auto-disable] — verify usernameClaimed / usernameUnclaimed pairs against live sites for maintainers auditing the database. --ai / --ai-model — run the AI analysis over the search results and stream a short investigation summary to the terminal. AI analysis --ai collects the search results, builds an internal Markdown report, and sends it to an OpenAI-compatible chat completion endpoint to produce a short, neutral investigation summary (likely real name, location, occupation, interests, languages, confidence, follow-up leads). Per-site progress is suppressed and the model's output is streamed to stdout. export OPENAI_API_KEY=sk-... maigret user --ai # pick a different model maigret user --ai --ai-model gpt-4o-mini The key can also be set as openai_api_key in settings.json . The endpoint defaults to https://api.openai.com/v1 , but openai_api_base_url in settings.json can point to any OpenAI-compatible API (Azure OpenAI, OpenRouter, a local server, …). See the settings docs for the full list of options. Tor / I2P / proxies Maigret can route checks through a proxy, Tor, or I2P — useful for .onion / .i2p sites and for bypassing WAFs that block datacenter IPs. # any HTTP/SOCKS proxy maigret user --proxy socks5://127.0.0.1:1080 # Tor (default gateway socks5://127.0.0.1:9050) maigret user --tor-proxy socks5://127.0.0.1:9050 # I2P (default gateway http://127.0.0.1:4444) maigret user --i2p-proxy http://127.0.0.1:4444 Start your Tor / I2P daemon before running the command — Maigret does not manage these gateways. Cloudflare bypass Experimental. The Cloudflare webgate is under active development; the configuration schema, CLI behaviour, and the set of routed sites may change without backwards-compatibility guarantees. A subset of sites in the database require a real browser to solve a JavaScript challenge. Maigret can offload these checks to a local FlareSolverr instance: docker run -d -p 8191:8191 --name flaresolverr ghcr.io/flaresolverr/flaresolverr:latest maigret --cloudflare-bypass < username > The bypass is opt-in ( --cloudflare-bypass or cloudflare_bypass.enabled in settings.json ) and only fires for sites whose protection field matches. See the feature docs for backend options and configuration. Contributing Add or fix new sites surgically in data.json (no json.load / json.dump ), then run ./utils/update_site_data.py to regenerate sites.md and the database metadata, and open a pull request. For more details, see the CONTRIBUTING guide and development docs . Release history: CHANGELOG.md .
