An all-in-one osu!standard cheat, sold behind a login from taikobuddy.com and shipped packed with Themida. What survives is not the vendor's build: Kat reverse engineered and cracked it, and Hazuki-San/Aoba cleaned the decompiled output until it compiled again. Aim Assist, Relax and a replay player, in one external program that never injects a DLL.- Status: Archived · Cracked copy · Vendor site gone · Source published 2021
- History Preview: fishy.moe/osubuddy
- Type: Standalone
- Cost: Paid
- Maintainer:
TaikoBuddy (original developer · sold it from taikobuddy.com), Kat (reverse engineered and cracked it · also behind Auto Assist Megumi), and 
Hazuki-San/Aoba (cleaned the decompiled source until it built again) - Download: none, and deliberately not linked. What survives is cracked source code, and this list does not host or link cheat source code.
- Lifespan: Cracked source published April to July 2021, 33 commits.
- Format: A single external window with a module toggle per cheat, rather than a loader plus a game overlay.
- Cheats:
- Aim Assist, which pulls the cursor toward the next hit object
- Relax, which clicks the notes for you
- A replay player that plays a selected replay back, and can interpolate or flip it
- Other features:
- Replay playback limited to mouse input only, keyboard input only, or both
Warning
Its own headline claim is false, and its own source proves it. The README says OsuBuddy "is fully external. It doesn't read or write memory, giving peppy no way of detecting it this way." The code imports both
Its own headline claim is false, and its own source proves it. The README says OsuBuddy "is fully external. It doesn't read or write memory, giving peppy no way of detecting it this way." The code imports both
ReadProcessMemory and WriteProcessMemory and carries a 23 file memory tree with pattern scanning that reads live gameplay state: the hit object manager, the ruleset, the viewport and the current cursor position. The Aim Assist works by reading the next hit object out of osu!'s memory. It is external in the sense that it injects no DLL. It was never a cheat that does not read memory.Note
Three people, and the README names all three. TaikoBuddy wrote and sold it. Kat reverse engineered it, credited in the file as "thank you, kat. for the reversed files". Hazuki-San/Aoba published the cleaned result, saying plainly that it was an old Themida build he only made compilable and that it was already cracked when he got it. The page opens by asking people not to contact TaikoBuddy for support on it, which is as clear a statement as you get that this is an unauthorised copy of something somebody was still selling.

Note
The crack is visible rather than claimed. In the published source the login method takes a username and a password and has an empty body, so any credentials pass and the account gate is simply gone. Five files still carry the token, RID and RVA comments that dnSpy and ILSpy leave behind, which is independent confirmation that this is decompiler output tidied by hand and not recovered original source.
