Lutris is an open source gaming platform for GNU/Linux. It makes gaming on Linux easier by managing, installing and providing optimal settings for games.

Lutris does not sell games; you have to provide your own copy of the games unless they are open source or freeware. Games can be installed anywhere on your system; Lutris does not impose anything.

Lutris relies on various programs referenced as 'runners' to provide a vast library of games. These runners (with the exception of Steam and web browsers) are provided by Lutris, you don't need to install them with your package manager.

We currently support the following runners:

• Linux (Native games)
• Steam
• Web
• Wine
• Wine + Steam
• Libretro
• DOSBox
• MAME
• MESS
• ScummVM
• ResidualVM
• Adventure Game Studio
• Mednafen
• FS-UAE
• Vice
• Stella
• Atari800
• Hatari
• Virtual Jaguar
• Snes9x
• Mupen64Plus
• Dolphin
• PCSX2
• PPSSPP
• Osmose
• Reicast
• Frotz
• jzIntv
• O2EM
• ZDoom
• Citra
• DeSmuME
• DGen

Lutris automates installation of games using configuration scripts written in JSON or YAML, which list the various files needed to install a game and can perform a series of actions on them. The syntax of installers is described in docs/installers.rst, and is also available on lutris.net when writing installers.

A web UI is planned to ease the creation of these scripts.

You can optionally create an account on lutris.net and connect this account to the client. This will allow you to sync your game library from the website to the client (not the other way around). If you wish, you can also sync your Steam library with your Lutris library on the website.

The client does not store your lutris.net credentials on your computer. Instead, when you authenticate, the website will send a token which will be used to sync your library. This token is stored in ~/.cache/lutris/auth-token.

The client, runner, and game configuration files are stored in ~/.config/lutris. There is no need to manually edit these files as everything should be done from the client.

lutris.conf: preferences for the client's UI

system.yml: default configuration for every game

runners/*.yml: runner-specific default configurations

games/*.yml: game-specific configurations

The game configuration can override previously defined runner and system configuration and runner configuration can override system configuration.

Runners and the game database =========================

The data necessary to manage your library and run the game is stored in ~/.local/share/lutris.

pga.db: your game library, game installation status, locations on the filesystem, and some additional metadata, all stored in an SQLite database

runners/*: runners downloaded from lutris.net

icons/*.png and banners/*.jpg: game images

The following command line arguments are available:

--version             show program's version number and exit
-h, --help            show this help message and exit
-v, --verbose         Verbose output
-d, --debug           Show debug messages
-i INSTALLER_FILE, --install=INSTALLER_FILE
                      Install a game from a yml file
-l, --list-games      List all games in database
-o, --installed       Only list installed games
-j, --json            Display the list of games in JSON format
--list-steam-games    List available Steam games
--list-steam-folders  List all known Steam library folders
--reinstall           Reinstall game

Additionally, you can pass a lutris: protocol link followed by a game identifier on the command line such as:

lutris lutris:quake

This will install the game if not already installed or launch the game otherwise (unless the --reinstall flag is passed).

Lutris is far from complete and some of the more interesting features have yet to be implemented.

Here's what to expect from the future versions of Lutris:

• Integration with GOG and Humble Bundle
• Integration with the TOSEC database
• Management of Personal Game Archives (let you store your games files on private storage, allowing you to reinstall them on all your devices)
• Game saves sync
• Community features (friends list, chat, multiplayer game scheduling)
• Controller configuration GUI (with xboxdrv support)
