Find accounts by username, email or phone.
Built for private and fraud investigators. Search across platforms, review matching profiles, and follow new leads as results arrive.
Three steps with zero setup
Pick your lookup
Username, email, or phone. Choose a search type and enter your query.
Watch results stream
Sources are checked in parallel. Hits appear the instant they’re confirmed.
Explore findings
Dig into profiles, cross-reference identities, filter and sort results.
Built for investigation workflows
Profile details, linked accounts, and search history. Filter, sort, and export your results.
Results as they're found
Every platform checked independently. Results stream to your screen as they arrive.
Recursive discovery
New usernames and emails found in results trigger fresh searches.
Broad coverage
Social networks, gaming, dev tools and forums.
Table & card views
Review available profile details, from bios to follower counts and locations. Browse in table or card layout.
Search history
Review past queries, search times, and result counts.
Explore matching profiles. Organized for review.
Review the profile details each source returns, from bios and follower counts to pinned repos and join dates. Available fields vary by platform. Open the banner, expand the bio, dig into raw fields. It's the real component, with sample data.

Your searches stay protected
Results are processed transiently rather than written to our database. The query and result count are saved to your history; the findings are returned to your browser without creating a stored archive.
Credentials protected at rest
When you use a password, it is stored only as a bcrypt hash. Session cookies are stored as one-way digests instead of reusable tokens, and every signed-in device can be revoked from settings.
Where results come from
Fingerprint queries supported platforms and third-party search providers when you run a search. Available information varies by source.

Fetch any platform
with one GET.
Every platform we support sits behind a predictable URL: /v1/{platform}/{handle}. Plain HTTP, JSON out. No SDK, no client library, no abstractions in the way.
- Same enriched profiles the dashboard renders
- Predictable URLs - easy to cache, easy to debug
- Per-key auth with rate limits and audit logs
