What you get
More than a list of links
Username checkers tell you a profile URL exists. IntelBase opens each profile and brings back what's on it.
Every matching account
The handle is checked on 580+ platforms, with false positives filtered out so you only see accounts that really exist.
Profile details
Display names, bios, profile photos, follower counts, and join dates collected from each account found.
Linked sites
Websites, link-in-bio pages, and other handles people list on their profiles, ready to pivot into a new search.
Locations
Cities and countries people put on their profiles, gathered into one place and placed on a map where possible.
Identity grouping
Accounts are grouped by the person behind them, with the reason for every link, so a common handle doesn't blur several people into one.
Activity timeline
Join and update dates across platforms in one timeline, showing where the handle was used first.
Identity grouping
Same username. Same person?
Lots of people register the same handle. A raw hit list mixes them all together and leaves you to sort it out. IntelBase compares every profile it finds and tells you who is who.
Profiles compared side by side
Names, bios, locations, and linked sites are compared across every account. A common name on its own is never enough: it takes something specific, like a shared website or one profile linking to another.
Profile photo matching
Accounts that share the same picture are linked together, and real face photos are preferred when choosing each person's avatar.
A clear verdict
Every lookup ends with a plain answer: one person, mostly one person, or several different people, with each account labeled.
Every link explained
Open any person to see why their accounts were linked: the same name and city, a handle that spells their name, a shared website, or the same photo.

Workflow
How it works
From a single username to a full report, in one search.
Enter a username
Type a handle in the dashboard search box or send it to the API. IntelBase detects that it's a username, not an email.
580+ platforms are checked
Every platform is queried in parallel and matching accounts stream into your report as they're found.
Profiles are compared
Names, bios, links, locations, and profile photos are compared to decide which accounts belong to the same person.
Pivot and share
Follow linked sites and emails into new lookups, map connections in the graph, and publish the result as a shareable report.
Built for
Who uses username search
OSINT & private investigators
Go from a single handle to a person's full online presence, with the noise from unrelated accounts already filtered out.
Threat intelligence
Track threat actor aliases across forums, code hosts, and marketplaces, and see where the same persona shows up.
Trust & safety
Check whether a seller, creator, or reported user runs other accounts under the same handle.
Digital forensics
Expand a handle found on a device or in a chat log into the accounts and profiles tied to it.
API
Build it into your stack
Run username lookups from your own tools. Every account, profile field, and identity group comes back as structured JSON, or streams as it's found.
