由社区维护的包含 700 多个网站的数据集,可根据用户名查找帐户 — 为 OSINT 和数字足迹工具提供支持。
WhatsMyName (WMN) is a community-maintained dataset that lets you find out if a username exists across hundreds of websites. If you're investigating a person of interest, verifying an online identity, or simply curious about your own digital footprint, this project powers the tools that make that possible.
Created in 2015 by Micah "WebBreacher" Hoffman, WhatsMyName started as a personal fix for a real frustration: existing username checkers were full of false positives. Over the years, contributions from people all over the world have grown it into one of the most widely-used username enumeration datasets in the OSINT community.
Head to whatsmyname.app -- a free, browser-based tool built directly on this dataset. No installation required.
Or check out the many tools below that use WMN.
WMN is a single, carefully maintained JSON file (wmn-data.json). Each entry describes how to check one website for a username -- what URL to query, what a successful response looks like, and what a "not found" response looks like.
Tools and scripts read this file and do the actual checking. That separation means anyone can build a checker, and the data stays accurate regardless of which tool you prefer.
For a site to be included, it must:
In May 2023, we removed the bundled checker scripts and shifted focus entirely to maintaining the data file. See the tools section below for checkers that use our data.

This project only stays useful if the detections stay accurate. Websites change their profile URLs, response codes, and page content constantly. We need contributors to help find new sites and fix broken detections.
You don't need to be a developer. Here's how to help at any level:
| Experience level | How to contribute |
|---|---|
| No technical background | Submit a site via this form |
| Comfortable with GitHub | Open an issue with a link to an example profile |
| Comfortable with JSON and HTTP | Fork the repo, fix or add a detection, and submit a pull request |
See CONTRIBUTING.md for detailed instructions on adding or fixing site detections, including format requirements and examples. Please also read our Code of Conduct.
