LETS Code Health

Latest Essential Tatoe Server

This server handles every non real time client feature, so:

  • Ingame scoreboards
  • Score submission
  • Screenshots
  • Replays
  • osu!direct, thanks to cheesegull
  • Tillerino-like API (partially broken)
  • osu!standard and taiko pp calculation with oppai-ng, made by Franc[e]sco
  • osu!mania pp calculation with a slightly edited version of osu-tools, made by the osu! team
  • catch the beat pp calculation with catch-the-pp, made by Sunpy and cythonized by Nyo


  • Python 3.6
  • Cython
  • C compiler

How to set up LETS

First of all, initialize and update the submodules

$ git submodule init && git submodule update

afterwards, install the required dependencies with pip

$ pip install -r requirements.txt

compile all *.pyx files to *.so or *.dll files using (distutils file). This compiles catch-the-pp as well.

$ python3 build_ext --inplace

then, run LETS once to create the default config file and edit it

$ python3
$ nano config.ini

finally, compile oppai-ng (inside pp/oppai-ng) and osu-tools (inside pp/maniapp-osu-tools). is a tool that allows you to calculate pp for specific scores. It's extremely useful to do mass PP recalculations if you mess something up. It uses lets’ config and packages, so make sure lets is installed and configured correctly before using it.
