# Melty

> Mashups and mods for the games you own. Press Play and Melty sets everything up, play together from one link, and publish your own with your AI.

Melty is a free Windows desktop app from Stella Montis Inc., backed by Y Combinator. Mashups run on games you already own. If a game is missing, Melty opens its store. Play downloads the mashup, installs what it needs, and starts the game. Uninstalling restores files. Multiplayer mashups include an invite link. You can publish new mashups with Claude Code or Codex.
