DeckReady
Point DeckReady at your Steam library and get a per-game confidence score showing which Proton build (vanilla, GE, CachyOS, LinUwUx-style custom patches) and which launch settings will actually get the game running, with notes on anti-cheat caveats and known regressions.
Linux PC gamers and Steam Deck owners who maintain large game libraries and waste evenings figuring out which Proton build to pick
- Steam library scan producing per-game Proton-build recommendations with confidence scores
- Live patch-tracker across GE, CachyOS, LinUwUx, and other community releases, refreshed hourly
- Anti-cheat and DRM risk flags (EAC, BattlEye, Vanguard, Denuvo) with notes on Linux status
- One-click 'report a regression' pipeline that forwards findings to Proton build maintainers
Custom-patched Proton builds like LinUwUx are proliferating as separate GitHub releases; gamers have no neutral place to learn which build their specific library needs, so they spend hours picking the wrong one and churning through ProtonDB threads.
Linux hit 3.05% of Steam users with Steam Deck shipments ~5.6M by mid-2025 and 330M hours played in 2024 (+64% YoY); ProtonDB remains the central community hub and custom Proton builds (GE, CachyOS) are proliferating on GitHub.Linux Gaming Reaches 3.05% on Steam Fueled by Steam Deck and Proton ↗ProtonDB | Gaming know-how from the Linux and Steam Deck community ↗
ProtonDB gives per-game compatibility tiers but not a per-build confidence score; ProtonPlus and ProtonUp-Qt are version managers/installers (not recommenders); ProtonVariants only compares env vars — none combine per-game scoring with build + launch-setting + anti-cheat recommendations.GitHub - Vysp3r/ProtonPlus: A modern compatibility tools manager ↗Proton Variants - dcog989.github.io ↗
Comparable Proton tools (ProtonPlus, ProtonUp-Qt, GE-Proton, Proton-CachyOS) are all free and open-source; the Linux/Steam Deck niche is small (~3% of Steam users) and hobbyist-driven, signaling weak willingness to pay for a recommendation layer on top.GitHub - Vysp3r/ProtonPlus: A modern compatibility tools manager ↗How to Install GE-Proton on Ubuntu, Fedora, and Arch - FOSS Linux ↗
Linux/Steam Deck growth is sustained (5.33% Steam share by March 2026, 5.6M Deck units) and custom-Proton fragmentation keeps the recommendation problem alive, but improving native Linux/anti-cheat support (e.g. Easy Anti-Cheat, BattlEye) could erode Proton's relevance over a multi-year horizon.Steam Deck Linux Statistics 2026 ↗
Core data sources already exist publicly (ProtonDB tiers, Steam store metadata, Are We Anti-Cheat Yet, Proton GitHub release notes), but per-game confidence scoring across multiple Proton builds plus launch-settings tuning requires substantial aggregation/heuristic work and ongoing maintenance as builds churn weekly.GitHub - CachyOS/proton-cachyos: Compatibility tool for Steam Play ↗GitHub - Vysp3r/ProtonPlus: A modern compatibility tools manager ↗
