What is asahi-web?

asahi-web is the front-facing appearance of the osu! server protocol, Asahi!

It's a project by me, that uses guweb's source code, but is made to work with Asahi.

Using native async/await syntax written on top of Quart and cmyui's multipurpose library, asahi-web achieves flexability, cleanliness, and efficiency not seen in other frontend implementations - all while maintaining the simplicity of Python.

A primary goal of asahi-web is to keep our codebase a developer-friendly API, so that programming remains about the logic and ideas, rather than the code itself.

gulag-web is written by Yo-ru and Varkaria, but me and other contributors are mainly writing asahi-web.


  • Some know-how with Linux (tested on Ubuntu 18.04), Python, and general-programming knowledge.
  • MySQL


Setup is relatively simple - these commands should set you right up.


  • Ubuntu 20.04 is known to have issues with NGINX and osu! for unknown reasons?
  • If you have any difficulties setting up asahi-web, feel free to join the Discord server at the top of the README, we now have a bit of a community!
