GameIndex

What GameIndex is

GameIndex is a free game launcher and library manager that brings libraries from multiple stores into one native app. It can sync Steam, GOG, Epic, Rockstar, Ubisoft, and Humble libraries, and supports manual imports. For finding and tracking games, it includes an IGDB-powered storefront, deals, a wishlist, activity tracking, and cross-platform achievement tracking. Customization includes six UI styles, theme options, and a Layout Studio for rearranging interface elements. It supports Windows and Linux, including Steam Deck; Linux features 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 layer as local-first and provides a Privacy & Data tab for viewing and wiping local storage. Secrets use the operating system keychain. GameIndex is free to use, modify, and distribute under the MIT License. Its maker characterizes it as a personal project with rough edges, rapid iteration, and possible breaking changes; release builds are unsigned and may be flagged by antivirus tools.
