Does it run on Linux?

Proton tier, anti-cheat status and Valve’s Steam Deck rating for 2,053 PC games. 921 run natively or perfectly under Proton, 624 are Deck Verified, and 287 are blocked by anti-cheat — which no amount of Proton can fix.

From ProtonDB, AreWeAntiCheatYet, Steam and Valve. Nothing here is Sifter’s own rating. Data baked 2026-10-05. What changed this week.

Native Linux build (363)

The developer ships a Linux build on Steam. No Proton involved.

Runs great under Proton (558)

ProtonDB reports these run perfectly or near-perfectly out of the box.

Playable under Proton (805)

ProtonDB reports these run with minor issues or after tweaks.

Runs badly under Proton (40)

ProtonDB reports frequent crashes or significant problems.

Blocked by anti-cheat (287)

Their anti-cheat does not permit Linux. This overrides everything else — a game can be flawless under Proton and still not run.

Building something? Take the data.

Free, no key, CORS-open. /api/linux/730 for one game, /api/linux?appids=730,1145360 for up to 200. Every response carries the verdict, the four facts behind it, the sources and the bake date. A 404 means Sifter has no data for that appid — never that the game fails on Linux.

Sifter puts every game you own — Steam, Xbox, Epic, GOG, Amazon, itch.io — in one library and launches any of it. Get the app. Switching your whole setup, not just your games? See what still needs a workaround.
