Melee Mod Studio
Melee Mod Studio is a modding workbench that runs entirely in the browser. It reads a copy of Melee that you already own, opens it through the File System Access API, and lets you edit the game in place: character attributes and move scripts, costumes and portraits, stage files, music, and 3D models. The whole editing path is client side, so the game data never leaves your machine, and the app deliberately does not host or distribute game images of its own. On top of the editor there is a marketplace of community cosmetic mods backed by Cloudflare D1 and R2, with thumbnails rendered from a mod's own model file in the visitor's browser when it ships without artwork.
Attention: You need your own legally dumped copy of the game, and a Chromium browser such as Chrome or Edge, because the workflow depends on the File System Access API. The app does not host or distribute game files.
