OpenBox is an open-source game library manager and launcher built for Linux. It brings PC games, storefront libraries, ROM collections, arcade sets, and emulator setups into one searchable catalog complete with artwork, metadata, session tracking, save management, and launch profiles. If you have used LaunchBox on Windows, OpenBox aims to do the same core job on Linux: organize a large library, enrich it with metadata and media, and launch games reliably from a single front end. The key difference is that OpenBox is built specifically for the Linux ecosystem and does not lock advanced library workflows behind a paid subscription. LaunchBox is a capable Windows application, but it has no native Linux build, and several of its advanced features require a Premium subscription. OpenBox addresses both gaps. It runs natively on Linux, is licensed under AGPL-3.0, and includes features like custom fields, ESRB filtering, list view, media packs, and Big Box couch-browsing mode at no cost. No account is required to use it. OpenBox integrates with the launchers and paths Linux users already have. It reads installed Steam libraries, imports games through Heroic for Epic, GOG, and Amazon titles, pulls tagged entries from Lutris for EA, Ubisoft, Xbox, and Game Pass, and supports Gameyfin self-hosted libraries. It also handles local ROM folders, MAME and FinalBurn full-set classification, ScummVM, RPCS3, Vita3K, and Xbox 360 import helpers. Emulator setup detects local binaries and can install emulators from Flathub with an update-all flow. The project offers two interfaces: a Web UI for the full feature set including a local REST API and Big Box mode, and a lighter Native UI for desktop use. Library data is stored locally as a JSON file, and cloud sync works through mounted folders using tools like Syncthing, Dropbox, or Google Drive. Big Box mode supports controller navigation for handheld and couch use, and the app is portable as an AppImage. The full README is longer than what was shown.
