GameIndex

What GameIndex is

GameIndex is a game launcher and library manager that brings collections from multiple stores into one native app. It can sync libraries from Steam, GOG, Epic, Rockstar, Ubisoft, and Humble, and it also accepts manual imports. For discovery, it includes an IGDB-powered storefront, deals, and a wishlist; activity and cross-platform achievement tracking help follow game use and progress. The interface can be personalized with six UI styles, theme customization, and a Layout Studio for rearranging elements.

The app supports Windows and Linux, including Steam Deck. Linux support includes configurable Wine and Proton runners, per-game compatibility settings, and AppImage and .deb packages. Listed integrations include Steam Workshop, Nexus Mods, Discord Rich Presence, RetroAchievements, IGDB, and HowLongToBeat. The project describes its social features as local-first, and Settings includes a Privacy & Data tab for viewing or wiping local storage. Secrets use the operating system keychain. GameIndex is free to use, modify, and distribute under the MIT License. Its maker describes it as a personal project that may have rough edges, breaking changes, and rapid iteration; release builds are unsigned and may trigger antivirus heuristics.

Who it suits

GameIndex suits PC players who want to gather libraries from several stores, make manual imports, and browse or track games in one app. It may also suit Linux and Steam Deck users who want configurable Wine or Proton runners and per-game compatibility settings.

Limits

The plan is free to use, modify, and distribute under the MIT License. The maker cautions that the personal project may have rough edges and breaking changes; Flatpak packaging, a community theme browser, and broader plugin hooks are listed as planned or in progress.

Getting started

1. Open the GameIndex project website on GitHub.
2. Choose the Windows or Linux platform.
3. Install through an available Linux AppImage or .deb package, if using Linux.
4. Connect supported game libraries or add manual imports.
5. Use the storefront, wishlist, tracking, and interface customization features.

Verdict

Choose GameIndex if you want a free, customizable launcher that gathers multiple PC game libraries and offers discovery and tracking tools. Linux and Steam Deck users get configurable runners and per-game settings. Look elsewhere if you need a project without the stated rough edges or unsigned release builds.
