概要

WhatsMyName App is a username enumeration tool that searches for the presence of a given username across hundreds of social media platforms, forums, and online services. By querying each site and analyzing the responses, it quickly reveals where a specific handle is in use or still available. Commonly used by OSINT investigators, security researchers, and journalists, the tool helps map an individual's digital footprint across the web. It is also useful for personal branding, allowing creators and businesses to find consistent usernames across platforms before signing up. The project is open source and maintained as part of broader OSINT resources, with a regularly updated list of supported sites and detection rules contributed by the community.

Skeptical, then convinced

I went in skeptical — most tools in this space overpromise. It actually delivers on direct links to detected profile pages, and useful for both OSINT and personal branding caught me off guard. Not designed for bulk or automated enterprise use is why this isn't a perfect score, still, I'd recommend giving it a real trial.

Compared a few options

Evaluated this against two competitors. Where it wins: useful for OSINT investigations and digital footprint mapping and covers hundreds of websites in a single search. Where it lags: web interface offers limited filtering options. On balance the feature set — especially useful for OSINT investigations and digital footprint mapping — justifies the 5 stars for our use case.

Solid for our team

We rolled this out across the team last quarter and free and open source. Useful for OSINT investigations and digital footprint mapping fits neatly into how we already work, and username lookup across hundreds of platforms removed a step we used to do by hand. Not designed for bulk or automated enterprise use, which is the main caveat, but it has held up under daily use.
