fingerprint.to and Seer
Both tools take a username, email or phone number and check it live across hundreds of platforms, so the account-discovery step overlaps. fingerprint.to is built around that step and goes deep on each profile it finds; Seer puts a smaller social sweep next to breached credentials, compromised device records and US people search. Many investigations are well served by running fingerprint.to for discovery and Seer for what sits behind the identifiers it turns up.
What fingerprint.to is
fingerprint.to is a public data search engine: enter a username, email or phone number and it checks 700+ platforms (its own figure, as of October 2026) in parallel, streaming each confirmed profile back as it is found. Every match opens as a full profile with fields such as bio, followers, location and join date, and Deep Search re-searches the usernames and emails it discovers. A separate People Search handles U.S. name lookups.

Where each is the better pick.
fingerprint.to
- In Revealer's September 2026 benchmark, fingerprint.to returned more profiles than Seer (under its previous name) on all three test handles and posted the highest hit rate of the large paid engines.
- Each hit carries more about the account itself, including account-state signals such as banned, suspended and last active, per the same benchmark.
- Deep Search follows the usernames and emails a search uncovers and maps the linked accounts automatically.
- Results export to CSV, JSON and text on every paid plan, which makes handing findings to a colleague straightforward.
- Search history can be switched off, and search results are processed transiently rather than stored.
Seer
- Seer searches breached credential rows and shows the source each row came from and its date.
- Compromised device records show everything captured from one infostealer-infected device, not a single row.
- US people search returns full public-filing profiles, with relatives and aliases, from Basic at $12.99 a month.
- Monitors watch an email or a whole domain and alert when it next appears, by email on every plan.
- The free check accepts a domain as well as an email, username or phone, with no account.
Start with one identifier.
Free runs 10 searches a day across breach and device records, and 10 each for people search and social. Withheld credentials unlock two a week, or a paid plan reveals them outright.
