Allodium is a launcher for your GOG library, made for Linux. It features cloud saves, updates and DLC management, non-GOG game/program import/installs, custom cover art settings, playtime and last-played syncing, and more.

I wrote this because I switched between Heroic and Lutris several times over the years, never quite being satisfied with either, so I wanted to build something that was a mix between the two to fit my needs. It is still in early development, so expect bugs sometimes.

What it does

• Fetches your GOG library, with the cover art.
• Manage patches/updates, and DLC, for your games.
• Download and install from GOG over the Internet, or from offline installer files you've already backed up.
• Runs Windows games with Wine or Proton. It fetches what it needs by itself, so there is nothing to set up first.
• Keeps your GOG cloud saves current, on its own when a game opens and closes, so you can carry on from another machine.
• Import non-GOG games/programs. Give it any picture on the web for the cover art.
• Tracks playtime and last played, and you can sync it to "tHe CLoUd".
• The library grid supports controller navigation. For the Steam Deck, you will need to enable Steam Input.
• Can turn on the MangoHud overlay and GameMode, either for everything or for one game at a time.

Getting it running

Any Linux

1. Download the file with the button above.
2. Right click it, open Properties, and tick the box that lets it run as a program. (In a terminal, that is chmod +x allodium-x86_64.AppImage.)
3. Open it like any other program.

Arch/Artix-based

There is a PKGBUILD script in the repository. In a terminal:

git clone https://codeberg.org/allodium/allodium.git
cd allodium
makepkg -si

Allodium then turns up in your applications menu with everything else.

Playing on more than one computer

Open AllodiumSync

Allodium can sync your playtime and last-played stats to an external server so you can keep your stats in sync across multiple devices.

Make an account on the sync page first. Then open Settings in Allodium, turn on Sync playtime and last played, check that the server box says sync.allodiumlauncher.sh, and sign in with the account you just made.

Already keep your playtime on lutris.net? Put lutris.net in that same box instead and sign in with the account you have there. They function exactly the same.

The top of the window tells you if it successfully synced or not.

If you'd prefer, you can also self-host your own AllodiumSync server very easily: README.
