What is an OSINT username search?
OSINT stands for open-source intelligence, which means gathering information from public sources. A username search checks whether the same handle is registered on many websites. People use it to trace the public footprint of an account, verify who they are talking to or see which of their own accounts are easy to link together.
How this username search works
Each site has a predictable profile address, such as github.com/username. The tool builds that address for every site on its list and asks the site whether a profile exists there. A normal profile page counts as a hit. An error page or a redirect counts as a miss. The checks run through our worker proxy.
How to read the results
- Found: the site returned a valid profile page for that username.
- False positive: the site answered in a way that looks like a profile but probably is not one. Some sites return a normal page for any name.
- Not found: the site reported no profile.

Limits to keep in mind
A match tells you that a username exists on a site. Whether the same person owns two accounts needs separate evidence. Many people pick a common name. Some sites block automated checks or limit how many requests they accept. Treat every hit as a lead that needs verifying.
Use it responsibly
Run searches only for investigations you are authorized to carry out, such as checking your own handles or researching a case you have permission to work on. Laws and platform rules differ by country, so check the rules that apply to you before you collect information about other people.
