Somtum Launcher
for Windows (x64)
1.0.2 (0.2 MB)
Recommended. One app for TumThai, TumThai!Next, osu!(stable) and the 2008-2015 clients, and it keeps them up to date. No install wanted? Get the portable version (0.1 MB).
Just TumThai!Next? Download the installer (186.5 MB) or the portable zip (179.2 MB)
Stream: TumThai · TumThai!Next
TumThai!Next is TumThai's performance stream, on tumthai-framework: a 500–8000 Hz input/audio/update rate, display refresh rate control, Vulkan and a latency counter. Same account, beatmaps and scores. Switch streams any time in the game (Settings → General → Updates) or the Somtum Launcher.
Patching osu!(stable) by hand?
The Somtum Launcher already does this for you. Without the launcher, start osu!(stable) through the somtum.fun patcher to play on somtum.fun. Set up by hand, it may not work as expected.
somtum.fun patcher
Windows and Linux (no macOS)
other platforms
Legacy osu! clients (2008-2015)
The Somtum Launcher installs and updates these for you. Download one yourself here.
Show Hide
Old osu!(stable) builds, rebuilt to play on somtum.fun: today's beatmaps load, Relax and Autopilot scores submit, and the updater stays off. Unzip one anywhere and run osu!.exe. They need Windows and .NET Framework 3.5 (a few 2015 builds use .NET Framework 4).
Can't find the build you want? Ask for it in our Discord server or on the forum.

Get beatmaps
Download maps in the game, or browse the beatmap listing here. Stuck? The FAQ and the list of error messages may help.
Antivirus or Windows blocking a download? Our downloads aren't code-signed (that would cost us upwards of 300€ a year), so Windows may say "Windows protected your PC" (click More info, then Run anyway), and antiviruses may block or remove the Launcher, the Patcher, pkms.dll, TumThai or the old clients by mistake. Add an exception (whitelist) for their folders, or turn real-time protection off just while you install. Only for files from this page. How to add an exception
