Find Any osu! Username with WhatsMyName App
osu! has more than 21.8 million registered accounts and around half a million new ones a month. It also does something almost no other platform does: profiles publicly list the account's previous usernames. That makes an osu! handle unusually valuable when you are tracing an identity. WhatsMyName App checks one alongside 731 other platforms in a single search.

Search osu! Username FreeWhat Is osu! and Why Username Searches Matter
osu! is a free rhythm game built around community made beatmaps, running since 2007. The player base is large and young, with over 21.8 million registered accounts, roughly 500,000 created every month, and a ranked library of more than 100,000 difficulties. Profiles live at osu.ppy.sh/users/handle and are fully public, showing rank, playtime, join date and the beatmaps a player has made.
The feature that matters here is the username history. Name changes on osu! are not free: you need to have held a supporter tag at some point, the first change is then free, and each subsequent one doubles in price from eight dollars up to a hundred dollar cap. Every purchased change is listed on the profile afterwards, visible to anyone. The osu! team will remove an old name on request if it exposes a real identity, but the default is that it stays on display.
That default is why this check earns its place. Most platforms let a person shed an old handle quietly. osu! publishes the chain. For anyone connecting a current account to something written years ago, or for a player wondering what their own profile reveals, the username history is the single most informative field on the page.
How osu! Usernames Work
Usernames are unique and form the profile URL at osu.ppy.sh/users/handle. The same path also accepts the numeric account ID, so a username lookup resolves and redirects to the canonical profile, which is why a valid handle behaves slightly differently from a missing one.
Changing a name costs money and leaves a public record. Because the first change requires having held supporter status and later ones escalate to a hundred dollars, casual renaming is rare and the history on a profile is usually short and meaningful rather than noise.
The privacy consequence is the thing to understand. If your first osu! username was a variation of your real name, and you later moved to a pseudonym, the old name is on your profile for anyone to read unless you asked for it to be removed. Given the age of much of the player base at signup, that situation is common.
- Usernames are unique across the platform
- Profile URL format: osu.ppy.sh/users/handle
- The URL also accepts the numeric account ID
- Name changes require supporter status and escalate to a $100 cap
- Every purchased name change is listed publicly on the profile

Enter the osu! username

Find the osu! result
Results stream in as checks complete. Look for the osu! entry showing confirmed or not found.
Read the username history
Open a confirmed result and look for the previous names listed on the profile. Each one is a separate handle worth searching in its own right.
Search the old names too
Run a second scan on any previous username you find. Old handles often resolve on platforms the current one does not.
Export the results
When the scan finishes, export every found account to CSV to keep the chain of names together.
What WhatsMyName App Shows for osu!
A confirmed result links to a public profile carrying join date, country, playtime, rank and any previous usernames. Join date and playtime together tell you whether the account is a long term player or recent, and the username history gives you extra handles to search rather than just confirming the one you had.
A not-found result means no account holds that name right now. Because names change hands only through purchased renames rather than expiry, this is a fairly clean signal, though a handle that was renamed away may have been picked up by someone else since.

Open WhatsMyName AppAfter Finding an osu! Account
The productive move after a confirmed result is to search the previous names as well. A person who moved from a revealing handle to a pseudonym usually left accounts behind under the old one, and those older accounts tend to be the less careful ones. This is the specific reason osu! is worth checking even when the person is not primarily a gamer.
Read playtime and join date rather than rank when you are assessing whether an account is genuinely the person's own. osu! accounts get bought and shared like any other, and a long slow playtime accumulation is much harder to manufacture than a rank number.
If it is your own profile, go and look at what the username history shows. If your first handle was some version of your real name, that is publicly attached to your account right now, and the osu! team will remove it on request if it exposes your identity. That request is the fix, and most people do not know it exists.
- Search every previous username as a separate handle
- Old handles usually lead to less careful accounts
- Playtime and join date beat rank for judging authenticity
- You can ask osu! to remove an old name that exposes your identity

Frequently Asked Questions about osu! Username Search
Do osu! profiles show old usernames?
Yes. Every purchased name change is listed publicly on the profile. It is one of the few platforms that publishes the chain of names rather than letting an old handle disappear quietly.
How much does an osu! name change cost?
You need to have held a supporter tag at some point. The first change is then free, the second costs eight dollars, the third sixteen, doubling each time up to a hundred dollar cap.
Can I remove an old username from my osu! profile?
Yes. If a previous name exposes your real identity, or could be used to link you elsewhere, you can contact the osu! account team and ask for it to be removed. It stays on display otherwise.
How do I find someone's osu! account?
Search the handle in WhatsMyName App and open the osu! result. Then search any previous usernames listed on the profile, since those are separate handles with their own footprints.
Why is osu! useful for tracing a username?
Because the public username history hands you the account's earlier handles directly. On most platforms an old name simply vanishes, so you would have no way to know it existed.
Is looking up an osu! profile legal?
How do I tell whether an osu! account is really the person's own?
Look at playtime and join date rather than rank. Accounts do get bought and shared, but a long gradual accumulation of playtime is far harder to manufacture than a high rank.
