GameIndex

A unified, cross-store game launcher and library manager.

Unify your Steam, GOG, Epic, Rockstar, Ubisoft, and DRM-free libraries into a single, fast, native experience — with discovery, deals & news, activity tracking, achievements, Linux/Steam Deck Proton support, a social layer, and a controller-first 10-foot UI.

A quick guided tour of GameIndex — the launcher, unified library, game pages, and more:

GameIndex is built for Linux gaming, not ported to it. The compatibility layer is configurable globally and per game, with no external helper scripts required:

• Runners — detect Steam/System Wine, CachyOS, Lutris, Heroic and community builds; download GE-Proton, CachyOS, Proton-EM, Wine-GE, Kron4ek and Soda releases in-app; install local archives; uninstall what GameIndex manages.
• Prefixes — shared default prefix or one per game, compatdata reuse for Steam titles, prefix inspection (arch, validity, version, size, linked games), clone/reset/delete, Wine tools and one-click winetricks packages.
• Launch pipeline — [gamescope] [gamemoderun] [mangohud] [umu-run | runner] game.exe, with DXVK/VKD3D, esync/fsync/ntsync, Wayland, WoW64, large-address-aware, DLL overrides, per-game env vars and exclusion lists.
• Display & performance — Gamescope (FSR/NIS, HDR, VRR, resolution/FPS/refresh controls), MangoHud logging, GameMode, PRIME/GPU pinning and FPS readback into Activity.
• Steam integration — reversible Wine/Proton launch-option merging in localconfig.vdf (skipped while Steam runs, one-time backup), Steam launch routes and the native launch-options picker.
• Logs & diagnostics — per-game Wine/Proton logs with a live viewer, Linux system diagnostics, anti-cheat runtime installs and runner maintenance.
• Packaging — AppImage and .deb builds with matching in-app updates.

GameIndex is built with — not just inspired by — excellent projects in the launcher space:

• Hydra Launcher — the clean, modern approach to game distribution.
• Playnite — the extensible, library-aggregation philosophy and customization depth.
• LaunchBox — rich metadata, media, and emulation-focused cataloging.
• Steam + GOG Galaxy — unified-library UX patterns.

We borrow the best ideas from each and aim to combine them into a single, lightweight native app.

• Node.js (≥ 18) + npm
• Rust (stable toolchain)
• Platform deps: see Tauri prerequisites

npm install
npm run tauri dev      # launches the native window with hot reload

Frontend-only iteration (no native shell):

npm run dev            # Vite at http://localhost:1420

npm run tauri build    # tsc + vite build + native bundles
