Web osu!mania Editor by sheepex_

osu!mania 1-18k Web-Editor (WIP)

osu!mania editor is a browser based beatmap editor for osu!mania. You load a

song, set the timing, place notes on a vertical playfield, and export a ready

to play .osu or .osz. Everything runs locally in the browser.

There is no account, no upload, and no backend. Your audio and your map never

leave your machine.

It is built with React, TypeScript, Vite and TailwindCSS, draws the playfield

on an HTML Canvas, and packages exports with JSZip.
