Can Bazzite Run Non-Steam Games and Launchers Like Epic, GOG, or Xbox Game Pass?

Yes. Bazzite ships with Lutris pre-installed, and Lutris can run games from most third-party stores. Bazzite also states that these launchers integrate cleanly into Steam Gaming Mode, so non-Steam titles can appear alongside your Steam library in a controller-friendly interface. The officially named examples are Xbox Game Pass (via Battle.net), EA App, Epic Games Store, GOG.com, itch.io, Rockstar Games Launcher, and Ubisoft Connect.

What "non-Steam" support actually covers

Bazzite's own description draws a line between two things:

• Running the game — handled by Lutris and other launchers, which can execute titles from most game stores.
• Presenting the game — handled by integration into Steam Gaming Mode, so the launcher and its games are reachable without dropping to a desktop.

That second point matters most on handhelds and home theater PCs, where you may never want to touch a keyboard. If a launcher only runs games but doesn't surface them in Gaming Mode, the experience degrades quickly on those devices.

Supported launchers and stores

Bazzite's page also mentions "your dad's old CDs" as a half-joking catch-all for physical media and other odd sources — a signal that the intent is broad compatibility rather than a fixed list.

How the integration works in practice

The mechanism Bazzite describes is: a launcher runs the game, and that game is then integrated into Steam Gaming Mode. From the user's side the flow is roughly:

1. Install or launch the third-party store through its launcher (Lutris is already there).
2. Add or let the launcher register the game.
3. The title becomes reachable from Steam Gaming Mode rather than only from a desktop session.

The expected result is a single, controller-navigable library instead of switching between desktop windows. Bazzite does not document the exact menu path for each launcher on its landing page, so treat per-launcher setup as something you confirm in Bazzite's own Gaming Guide.

Before you commit: check compatibility first

Running a launcher is not the same as running a specific game well. Bazzite points to two community-maintained resources for that question:

• ProtonDB — community compatibility reports, primarily for Steam/Proton titles.
• GamingOnLinux — broader Linux gaming coverage.

For a non-Steam title, the practical check is whether the game itself works under Proton or Wine, not merely whether the store launches. A store can open fine while a specific anti-cheat-protected multiplayer game still refuses to run.

Who this fits

• Good fit: you have libraries spread across Epic, GOG, itch.io, or Ubisoft and want them in one Gaming Mode interface on a handheld or TV.
• Check first: your main game uses kernel-level anti-cheat, or you rely on a store not named above.
• New to Linux gaming: Bazzite explicitly targets Linux newcomers and points to its Gaming Guide for current tips, so start there rather than assuming a launcher will behave exactly as it does on Windows.

One more note from the source: Bazzite is image-based, so if a launcher or driver update breaks something, you can boot the previous image or rebase to a last-known-good release and pin it. That rollback path is the main safety net when experimenting with third-party launchers.
