Username Availability Checker
Ask Instagram, TikTok, and X whether a username looks taken. A miss is not a reservation.
Check a username against Instagram, TikTok, and X from this site’s server, because those sites block a browser directly. A result can be taken, free, or couldn’t check when the platform refuses the lookup. It is a signal, not a reservation.
Worked example
Checking “nicebuild” asks Instagram, TikTok, and X from the server. A profile the platform confirms is marked taken. A clear miss is marked looks free. A block, a login wall, or a timeout is “couldn’t check”, not a crash.
FAQ
- Why not check in the browser?
- Those sites do not allow a page on this domain to ask them directly. The check runs on the server.
- Does “looks free” mean I can register it?
- No. The platform can still reserve the name, or the lookup can be wrong. Confirm on the signup form.
- What if every row says couldn’t check?
- The platforms refused or timed out. Try again later. The page does not guess.
