Archipelago

What Archipelago is

Archipelago randomizes supported games and connects them in a shared multiplayer session. An item found in one player’s game can be assigned to another player and sent to that player’s game over the internet. Sessions can be synchronous, with participants playing at once, or asynchronous, with players connecting at their own pace. Supported games can also be generated for single-player use through the website or installed generator software. For online generation, users upload a YAML configuration or a ZIP of configuration files; the site uses the current Archipelago release. To host a game, users can upload a locally generated ZIP or multidata file, then provide players with a tracker and patch files. Race games omit spoiler logs and apply protections that vary by game, such as ROM encryption or cheat-mode removal. The project provides guides for supported games, including instructions for macOS clients, and directs players and developers to Discord for questions. Archipelago is free and open source, with support for Linux, macOS, web, and Windows. The supported-games page lists games included with its software and points to guides for custom worlds and other games.
