Username lookup
Find every profile behind a username
People tend to reuse the same handle everywhere: on social networks, forums, gaming platforms, code hosts and dating apps. A username search takes one handle and checks it against about 1,000 websites at once, so you see in about 30 seconds where that name is registered and what each profile reveals.
TraceFind does more than say “exists”: for every match it opens the public profile and extracts what is shown there, such as display name, bio, profile picture, location, linked websites and the platform’s permanent account ID. False positives are filtered out daily, so the list stays usable.

How it works
Three steps, no setup
Enter the handle
Type the username without the @, for example
janedoe_92. Letters, digits, dots, dashes and underscores all work.We check ~1,000 sites
Each site is queried the way a visitor would look the profile up. Matches are verified so pages that merely say “not found” are dropped.
Review and export
Open each profile, export the results as PDF, JSON, CSV or TXT, or place them on the investigation canvas to dig further.

FAQ
Frequently asked questions
How do I find all accounts with the same username?
Enter the username above and start the search. TraceFind checks about 1,000 websites in parallel and lists every site where an account with exactly that name exists, with a link and the profile details. Most searches finish in about 30 seconds.
Does a match mean it is the same person?
Not necessarily. A short or common handle such as alex is likely to belong to different people on different sites. Compare names, pictures, bios, locations and linked accounts across profiles before drawing conclusions. Rare, specific handles are a much stronger signal.
Which sites are checked?
About 1,000 sites: major social networks (Instagram, TikTok, X, Reddit, Facebook, Telegram), developer platforms (GitHub, GitLab), gaming (Steam, Twitch, Chess.com), creative and music sites, forums and many regional networks. The list is maintained continuously and sites that return false positives are removed.
Should I include the @ sign?
No, enter the handle without the @. For @janedoe_92 search janedoe_92.
Can I search an email or phone number instead?
Yes. Use the email search to find accounts registered with an address and the data breaches it appears in, and the phone search for messengers and social networks linked to a number.
Will the person know I searched for them?
No. TraceFind only reads public pages and uses sign-up and password-reset checks that do not send anything to the account owner. Nobody is messaged, called, followed or notified, and your search is not visible to anyone else.
How much does a search cost?
A new account gets 15 free credits, enough for 3 searches; these show a preview with how much was found in each category. Credits cost €0.25 each, including VAT, and a full search costs 5 credits (€1.25). A search that finds nothing is refunded. Buying credits also unlocks every preview you already ran. See pricing.
Is it legal to use TraceFind?
Searching publicly available information is legal in most countries, but what you do with it is regulated. Use TraceFind only for a legitimate purpose, such as checking your own exposure, fraud prevention, due diligence or authorised investigations, and handle results according to the data-protection law that applies to you (for example the GDPR). Stalking, harassment and doxxing are forbidden by our terms.
Is my search stored?
Each search is saved as a report in your private history so you can reopen and export it. You can delete reports at any time. An account needs no email or name: the account ID is enough. If you sign in with GitHub, the email address GitHub shares is stored with the account.
