WhatsMyName is a community-maintained JSON dataset of 700+ websites with rules for checking whether a username exists on each site. It powers OSINT username-enumeration tools and the whatsmyname.app web checker.

Use cases

• find accounts by username across social media sites
• osint username lookup for investigations
• check my own digital footprint
• verify if a username is taken on hundreds of websites
• build a username enumeration tool
• reconnaissance for cybersecurity investigations

When to choose

• you need accurate, community-validated username enumeration data with low false positives
• you're building an OSINT tool and want a maintained site-check dataset
• you want to audit your own online presence

When to avoid

• you need to search sites behind logins or paywalls
• you want a ready-made GUI checker rather than data (use whatsmyname.app or downstream tools)
• you need email or name-based person search rather than username lookup
