What you get
One handle in. A map of where it lives.
Coverage spans social networks, gaming, developer platforms, tech and products, hobbies and interests, finance and crypto and more. For each match you get the profile as the site shows it, not a guess.
The account and its link
Which site, the exact handle as the site displays it, and a link you can open to check the profile yourself.Core profile fields
Display name, avatar, bio, and follower, following and post counts, wherever the site makes them public.Extended fields (Pro and Max)
Location, website, join date, last active date, linked accounts and platform details such as ratings, levels or repository counts.Leads (Pro and Max)
Other usernames and emails that a matched profile lists in public, each one ready to search with a click.Category, sort and filter
Narrow a long result set to developer platforms or gaming, sort by followers, or search inside the results.Export (Pro and Max)
Download the result set as CSV or JSON for case notes, spreadsheets or your own tooling.
Reading the results
A match is where the work starts.
Username results are fast and broad, which makes them easy to over-read. Four habits keep them honest. The full guide goes deeper.
- 01
Ask how common the handle is
A distinctive handle like nightowl_dev that shows up on twenty sites probably points to one person on many of them. A short or common word matches different people on every site. The more generic the handle, the less any single match means. - 02
Look for things that agree
Treat profiles as related only when details line up: the same avatar, a matching display name, a bio that mentions the same city or job, or one profile linking to another. One overlap is a hint; several independent overlaps are evidence. - 03
Check the dates
Join dates and last activity tell you whether accounts could belong to the same period of someone's life. A handle registered in 2012 and abandoned may have nothing to do with an active account of the same name. - 04
Treat no answer as unknown
Some sites block automated checks or change their pages. Those are counted as no answer, not as not found. Absence from the results is not proof that an account does not exist.
Limits
What username search cannot do
- It only finds accounts on supported sources, and only where the site confirms the account in public.
- Private, suspended and deleted accounts usually do not show up, or show up with no details.
- It matches the exact handle. Variations such as nightowl.dev or night_owl_dev need their own searches.
- It cannot tell you who owns an account. That takes corroboration a person has to do.
Responsible use
Leads, not identity.
Use username search for investigations, fraud checks, brand protection, research and checking your own footprint. It is not a background check and must not be used for employment, tenant, credit or insurance decisions, or to stalk or harass anyone.
Anyone can ask us to block searches for a username they use through the opt-out page. The Acceptable Use Policy has the full rules.
FAQ
Common questions.
How many sites does username search check?
Currently 420+ sources for usernames, across 20 categories. The list changes as sites change; sources that stop answering reliably are switched off rather than guessed.
Do I need to type the @?
No. A leading @ is removed automatically. Usernames cannot contain spaces.
Are adult sites included?
Adult sites are excluded from results unless a signed-in user turns them on in settings.
Why did a site I know the person uses not show up?
The account may use a slightly different handle, be private or deleted, or the site may not be one of the supported sources. Some sites also block checks at times; those count as no answer.
Does a search contact the account owner?
No. Username checks read public profile pages and public endpoints, the same ones a browser would load. They do not log in to, follow or message the account.
