# WhatsMyName Apps

> Free username search at https://whatsmynameapps.us/. Type one username (or up to five) and the tool checks 3,165+ public websites in 19 categories, live, and labels each one Found, Not found, Blocked or Unknown. Found results can show the public display name, avatar and bio. Results export as JSON or CSV. No sign-up. The site shows ads to stay free; searched usernames are never shared with advertisers. The username is sent to our server only to run the check and is not stored or logged.

WhatsMyName Apps (domain: whatsmynameapps.us) is an independent tool. It is not affiliated with or endorsed by the WhatsMyName project, Sherlock, Maigret or any site it checks, and it is a different site from look-alike domains with similar names. The site list merges the open-source WhatsMyName dataset (CC BY-SA 4.0) with the Sherlock and Maigret lists (MIT). It searches by username only: not by real name, phone number or address. It is not a people-search site or a consumer reporting agency and must not be used for FCRA purposes (employment, housing, credit, insurance).

## Facts
- Sites checked: 3,165+ (merged and de-duplicated; the count updates when the lists change)
- Statuses: Found, Not found, Blocked (the site refused automated checks), Unknown (unclear answer or timeout)
- Extras: up to 5 usernames per search, domain availability via public RDAP (.com, .net, .org, .io, .us, .app, .dev), 10 interface languages
- Price: free. No account, no API, no CLI
- A Found result is a lead to verify, not proof that one person owns an account
