Our verdict on DeckyVault
DeckyVault is an open-source, community-driven database for Steam Deck OLED, Steam Deck LCD, and Steam Machine compatibility, performance metrics, and game settings. It suits Steam Deck owners who want compatibility labels alongside measured performance, rather than a simple playable-or-not verdict. The web platform combines game search with Proton and native status, anti-cheat information, online-play tracking, Steam reviews, artwork, and statistics.
Performance tracking is the product’s central focus. Historical graphs compare FPS results across game, Proton, and SteamOS versions, while device presets cover Steam Deck OLED, LCD, and Steam Machine configurations. The Decky Loader plugin records MangoHud FPS, TDP, and temperature data, detects Steam Deck LCD or OLED hardware, and supports one-click benchmark uploads with JSON export. Integrations with Steam, MangoHud, and SteamDB connect benchmark records with game and platform information. DeckyVault is open source and has a free plan.
The setup path combines the web service with a Linux-compatible Decky Loader plugin for recording and hardware detection; the hardware scan is provided by that plugin on Steam Deck. Community and documentation channels provide support. Choose DeckyVault if you want version-aware benchmark history, per-device settings, and visibility into Proton, native, anti-cheat, and online-play status in one search experience. It is less suited to readers seeking a broad, platform-agnostic checker or a browser-only hardware scan, since its measurement workflow is centered on Steam Deck hardware and community-submitted sessions.
