Run a background check on a username to find all accounts and profiles associated with that person across the internet.
Investigate a suspect or person of interest by mapping their online presence and discovering connected usernames and accounts.
Build a people-search or background-check product by embedding Maigret as a Python library in your application.
Use the Telegram bot to quickly search for usernames without installing software on your machine.
Maigret is an open-source OSINT (Open Source Intelligence) tool that searches for a person across the internet using just their username. You give it a single username, and it checks over 3,000 websites, social networks, forums, photo platforms, dating sites, coding communities, to see if that username exists anywhere, then compiles everything it finds into a report. The tool is aimed at investigators, security researchers, journalists, and anyone doing background research on a person. It goes beyond a simple username check by also extracting profile information from found accounts, following links between profiles to find additional usernames, and building a connected map of a person's online presence. Reports can be exported as PDF, HTML, interactive graphs, or spreadsheets. For practical use: type in a username you found on one platform, and Maigret tells you where else that person appears online, often revealing real names, locations, profile photos, and connections between accounts. An optional AI analysis mode can summarize the findings in plain English. There is also a Telegram bot if you do not want to install anything. Built in Python and free to use, it requires no API keys for basic operation. Commercial use requires a separate license. It is used by professional social media intelligence platforms as a core engine. For a founder or vibe coder: this is a ready-to-run investigation tool, not a building block. If you are building a people-search or background-check product, you could embed it as a Python library, but most users just run it directly from the command line.
