The modern compatibility index for Steam games on Linux.
A modern compatibility database for Steam games on Linux. Current answers, editable reports, better filters, and troubleshooting that keeps up with Proton.
One database, five ways in.
Answer “can I play this on my setup?” first, then let technical users drill into the evidence.
Can I play this?
- A clear recommendation: use Proton, use native, or avoid for now.
- Confidence and freshness shown up front, in plain English.
- Big warnings for anti-cheat, launcher, and multiplayer breakage.
Drill into the evidence.
- Filter by GPU, driver, distro, kernel, Wayland/X11, and Proton branch.
- Raw environment tables, exact launch options, and report diffs.
- Separate Native and Proton scores — never collapsed into one.
Good reports beat noise.
- Edit reports without losing history — every change is versioned.
- One-click confirmations keep fresh games fresh.
- Library-aware prompts surface what actually needs a report.
What we’re fixing.
The same crowdsourced idea, rebuilt around freshness, correction, and clarity.
Current answer first
Stale reports lose weight over time and get flagged after major Proton, driver, or anti-cheat changes — so the top of the page reflects what's true now.
Native vs Proton, scored separately
A native build that runs worse than Proton no longer hides behind a single label. Each path gets its own score and a recommended pick.
Structured fixes, not wiki soup
Launch options are categorized (required to launch, performance, hardware-specific, preference) with helpful/not-helpful votes and last-confirmed dates.
Editable, never erased
Reports have a stable identity with append-only history. Fix a mistake without leaving confusing duplicate posts behind.
Contribute without the friction.
Create an account with email or a passkey — no Steam login required to browse, vote, or file a basic report. Link Steam only when you want library sync, ownership-backed reports, and personalized compatibility for your games.
- Optional Steam linking for library and recently-played prompts.
- Ownership-backed reports get a verified badge.
- Desktop and handheld reports stay in their own lanes.
